Pump i.e. axial-piston pump, for integration into e.g. pane washing device of motor vehicle, has valve units provided at respective end sides of housing, so that conveying partial volumes are generated with movement of piston

摘要

The pump (10) has a piston (12) axially and movably accommodated between end sides (11A, 11B) in a tubular housing (11). The piston exhibits a magnet (13) e.g. rare earth magnet such as neodymium magnet, which cooperates with a field coil (14A) arranged in and/or at the housing. Valve units (15A, 15B) are provided at the respective end sides of the housing, so that conveying partial volumes are generated with axial movement of the piston towards the respective end sides. The piston is formed as an injection molding component. The magnet is formed as a plastic-bound magnet.
