Реферат: The oscillator pump (1) has a housing (2) with a disk (4), forming at least one ring zone (6) in the radial direction between the disk and the housing. It is separated into chambers (8) in the peripheral direction by a divider (7) mounted to the housing and/or disk. The housing or the disk is oscillated by the drive, keyed against rotation around it axis, to alter the chamber volumes at a suction or pressure side of the pump. The pump outflow control is set according to the interior pressures in the chambers, and the position of the outlet flow control body. The pump outflow control is a valve strip, to control the flows from the chamber outlets and block the link between the chambers and the pressure side of the pump. The valve strip covers the outflows at the outer side of the housing.
