Rotary vane pump, has T-shaped slide gate valve to slide into radial or tangential slots of rotary slide piston, and two side cover plates including eccentric recess for supporting valve, where supporting arm of valve slides into recess

摘要

The pump has a rotary slide piston (21) arranged on a drive shaft (14), where the piston has radial or tangential slots. T-shaped slide gate valve (34) slides in the slots and a hollow cylindrical housing whose inner diameter is eccentric to the drive shaft lies in the slots. Two side cover plates (24, 40) include an eccentric recess (29) for supporting the valve. A supporting arm of the valve slides into the recess (29).
