Abstract

1,247,160. Centrifugal pumps. DOWTY FUEL SYSTEMS Ltd. Nov.27, 1969 [Dec.4, 1968], No.57461/68. Addition to 974, 958. Heading F1C. [Also in Division F2] The centrifugal pump inlet valve of the parent Specification has a modified closure member comprising a movable cylinder 28 co-operating with a stationary member 23 shaped as shown to provide an approximately exponential relationship between the flow cross-sectional area and the position of the actuator piston (35). In a modification (not shown) conical surfaces 26 and 43 can be replaced by a continuously curved surface.
