Oscillator pump, as a hydrostatic oil pump, has at least two pump zones with individual pump functions formed by the housing and disk and at least one divider, which can serve a number of oil circuits

摘要

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 housing, disk and at least one divider form at least two pump zones, with individual pump functions. The disk is a ring disk, oscillating against the housing. An outer ring (14) is around the disk holding it, with a cover.
