Abstract (en)
A rotary pump (1) of fixed cubic capacity and variable flow, particularly for oil, has a support body (2) bounding a seat (3) comprising an intake chamber (31) adapted to be connected to an oil tank via a relative intake opening (34) and a delivery chamber (32) adapted to be connected to a circuit using the oil via a relative delivery opening (35), the delivery chamber (32) and the intake chamber (31) being separated from one another by a member (40) which can be moved in order to vary, in operation, the flow of compressed oil entering the delivery chamber (32) and is actuated by an actuator unit (50) as a function of the delivery pressure. <IMAGE>
