Abstract

898,565. Engine distributing valves. MIDLAND PNEUMATIC Ltd., and COOPER, R. Oct. 23, 1959 [Aug. 19, 1958], No. 26572/58. Class 122 (2). [Also in Group XXIX] In a longitudinal slide valve of the type adapted to control the delivery and exhaust of pressure fluid to and from apparatus such as air-operated piston machines, and with the objects of avoiding corrosion and the need for lubrication and of reducing wear at least one of the faces which are in sliding contact is made of polytetrafluorethylene. Valve body 6 houses a longitudinally slidable operating piston 14 which is responsive in both directions to air control pressure supplied to its opposite ends at 28. A " D " slide valve member or disc 17 made of polytetrafluorethylene is positioned between shoulders 16 on the piston and is spring-urged into contact with a valve face provided on a cover 9 of the body so as to control the delivery ports 12, 13 and exhaust port 11 in this cover. Pressure fluid is supplied to a chamber 7 of the valve at 8. Also the cylindrical parts of the body 6 in which the piston 14 slides are coated with polytetrafluorethylene to avoid sticking in the event of non- lubrication.
