Description

[Detailed description of the invention] conduit connector Technical field The present invention relates generally to connectors, and more particularly to directing pressurized fluid through a bulkhead or partition. Is it possible to seal the fluid pipeline? , relates to a connector for connecting to.

background masquerade Externally through the wall of the cover of the engine cylinder head or valve rocker arm and a long bulkhead adapter between the fuel lines to connect the internal fuel supply lines. Connect at least two fuel supply lines at that location by connecting a connector or union. It is common practice to provide joints.

U.S. Patent No. 3,402,703 and 6Y dated September 24, 1968, 1970 No. 3,489,435, dated Jan. 13, the adapter has a cone on each end. having a shaped counterbore and an externally or internally threaded end. Each fuel line Has a mounting member or nut that can be screwed onto the corresponding end of the adapter and slidable. Connect the end of each fuel passageway to the corresponding end of the adapter through a 7-erule or collar between them. Press into the conical counterbore.

How many of these typical bulkhead fuel line connections have multiple joints in the fuel supply line? The fire was caused by the fact that the assembly of two fuel lines passing through the bulkhead was relatively complex and time-consuming. , as well as improper assembly and the consequent high pressure of fuel due to various joints in the fuel supply line. This may also provide further opportunities for leaks.

Additionally, internal and external fuel lines can be routed to low-vibration engine cylinder heads or Minimize vibrations in the conduit by solidly bonding to the cover of the rocker arm is desirable. U.S. Pat. No. 3,404,703 discloses that the adapter has screws in It has external threads that fit into the opening.

However, such fastening means are limited in that the adapter is typically made of steel and the bulkhead is made of aluminum. This is not satisfactory for parts made of lightweight and soft materials such as aluminum. Kayo In such cases, the adapter may be over-pitted or over-torqued. Doing so may overstress the septum or wear out internal threads in the septum. It's possible.

The present invention aims to overcome one or more of the problems as described above.

Disclosure of invention In one aspect of the invention, a conduit connector is disclosed, the connector being on a first conduit. and the other end formed on the second pipe, and these ends are tightly sealed. Complementarity for sealable mating and direct sealable contact between fluid conduits and means for removably coupling it in the same manner.

Conventional bulkhead fuel line adapters connect multiple fuel lines between external and internal fuel supply lines. Patent-like orientations featuring path joints are relatively complex and time-consuming to assemble. , many fuel passages in the adapter, giving even more opportunities for improper assembly In each case, high-pressure fuel leaks can inevitably occur.

The present invention generally has a single fuel line junction where the fluid line assembly meets the bulkhead. It is intended to provide a conduit connector to pass through. Assemble the single connection correctly is relatively easy to install and eliminates many potential sources of high-pressure fuel leaks due to improper assembly. It should be minimized.

Alternatively, the sleeve 102 may have a transverse hole I drilled through its central portion, for example. O! Alternatively, notches (not shown) may be provided at either end of the sleeve 102. can.

Industrial applicability The assembly and operation of the present invention will be apparent from the foregoing, and further includes: Provide a simple explanation of assembly and operation.

To assemble the fluid conduit assembly/6 through the housing wall/6, do not bend and A non-swaging internal conduit is passed through the second collar of the mounting member and the perforation 77. vinegar. Temporarily shift the mounting member U and attach the second collar to the end S of the internal conduit n. , and then the end points are enlarged so that the internal truncated male surface is ≦, and the external shoulder is A snug fit is formed between the collar and the second collar and the internal conduit. Internal conduit The opposite end of can be provided with a third holding part qo at the same time, which is the opposite end of The third collar U is pressed onto it by temporarily shifting it while the parts are cold-formed. be taught. The second conduit fits within the housing d and is connected to the connecting means S6 and the fluid jet. It can be bent into a predetermined shape for connection with the nozzle p.

The annular seam A/qr is placed in the groove 100 of the second collar, with the second collar being , against the internal shoulder 71 of the mounting member 5t, the mounting is placed snugly in the hole 77.

When the housing cover q is removed from the housing U, the internal conduits and assembly The component parts sr, Ω, tr, qo.

qr is placed in the housing d, and the mounting member 5g is attached to one side of the hexagonal head end d. is in contact with the flat surface 7B of the housing wall rib 7S in the radial direction, and the outer shoulder 70 is in contact with the inner surface of the housing wall lB, and the external threaded part of the mounting member st is housing wall 16 until portion 72 projects outwardly from the outer surface of housing wall 16. is slidably placed through the hole/4' in the section. Annular sea A/79 is threaded It is placed on the exterior of the mounting member sr between the shoulder 72 and the guide 7da. First holding part 6 II is loosely screwed into the mounting threaded end 72. Burn the third holding part 90. Screw the material injection nozzle unevenly. At this point, tighten the first holding part so that it can be screwed in. , thereby attaching the mounting member St to the outer and inner housing walls. and tighten the housing wall part 16 to tighten the first holding part 64' and the mounting member 5g. Subject to harmless compressive stress between part d. This causes unfavorable stress on the housing. rocker arm housing without breaking the housing or breaking the housing. To ensure that the fluid conduit assembly 12 can be supported and fixed in a low vibration structure such as It is something that The external conduit 20 has an end surface 12, I&, in direct sealable contact. The second holding part 66 can be screwed onto the threaded end n of the mounting member S. so that the end surfaces rx and tt are sealed together. I'm going to growl. Bulkhead fluid conduit connector IO with a single fluid conduit junction Relatively easy to assemble and maintain compared to adapters with fluid path junctions. is less time-consuming and eliminates many high-pressure fuel leaks due to improper assembly. It minimizes potential causes.

In operation, a fluid, such as fuel, is transferred from the fluid supply tank 36 to the fluid transfer line 3t. and then through the pump section, where the fluid is periodically metered and pumped out under high pressure. Part pipe 20, internal pipe n1 is sent through the fluid injection nozzle, and is sent to the combustion chamber of the engine. sprayed into μ.

If the second holding part 6B is not tightened correctly, the end face l of the single fluid path connection ko2. A high-pressure fluid leak between R and B usually occurs when the lubricating fluid circulating inside the housing It is prevented by seals qq, qt from entering and contaminating or diluting it.

In FIG. 2, the fluid leaks into the cavity 9 of the second retainer and into the first collar 60. or along the threaded end 72 of the mounting member sr. Therefore, the liquid can flow out of the second holding part 66. In Figure 3, the fluid leak is from one of the collar passages 96 and the second annular clearance 10B, or from the first annular clearance 10A. Arance IO’t, installation parts! r' through the threaded end 72 of the second retaining section. leaks out of the product.

While the present invention has been illustrated and described with reference to preferred embodiments, it is limited by the scope of the claims. Variations that fall within the scope of the invention are possible.
