Abstract

1291334 Rotary pumps and motors STAL REFRIGERATION AB 26 Nov 1970 [27 Nov 1969] 56208/70 Heading F1F Capacity of an eccentric vane rotary pump or motor 3 is steplessly regulated by a valvedisc 4, mounted in at least one of the end-walls, and having a peripheral channel 5, which is in permanent communication with a pump suction channel 8, and by turning the disc 4, through a spring-retracted rack 18 engaging teeth 19 on the disc, can be registered with the pump pressure chamber 6 to connect it to suction 8. A spring 9 holds the valve-disc 4 against a face of the pump housing, and yields under delivery pressure to relieve to suction. The rack 18 may be actuated manually or by fluid-pressure supplied by an auxiliary pump (14), Fig. 4 (not shown), through a solenoid-valve energized in response to temperature or pressure in a vaporizer of a cooling system.
