Abstract

1,085,419. Circumferential-flow pumps. FORD MOTOR CO. Ltd. Aug. 18, 1966, [Oct. 22, 1965], No.37017/66. Heading F1C. In a circumferential-flow pump of the type comprising a rotor 12, Fig. 1, formed with a bladed semi-toroidal chamber 34 co-operating with a semi-toroidal chamber 36 formed in a stator 14 to form jointly a toroidal chamber 38 through which air or other fluid is pumped from an inlet to an outlet separated from the inlet by a seal member 44 extending across the stator semitoroidal chamber, the inlet comprises a single port 46, Fig. 4, while the outlet has a number of circumferentially spaced ports 48 disposed either in a single row or in two radially spaced rows. Each outlet port 48, which may be of increasing cross-sectional area to act as a diffuser, has its axis arranged substantially tangential to the direction of flow. The outlet ports 48 may be circular, elliptical or rectangular in crosssection. The rotor 12 is journalled on the enlarged end 22 of a stationary spindle 24 which supports the stator 14. Excessive pressure developed by the pump is relieved by axial movement of the stator relative to the rotor against the action of a spring 30 having an adjustable abutment 32.
