Abstract
Offenbart ist eine hydrostatische Pumpe, insbesondere eine Flügelzellenpumpe, bei der der Verdrängerraum stirnseitig durch einen Gehäusedeckel (14) und eine Seitenscheibe (16) begrenzt ist. Letztere wird über ein Federelement (30) in ihre Anlageposition vorgespannt und bildet den stirnseitigen Abschnitt des Pumpengehäuses für die Flügelzellenpumpe. Disclosed is a hydrostatic pump, in particular a vane pump, in which the displacement space is delimited on the end face by a housing cover (14) and a side window (16). The latter is prestressed into its contact position by a spring element (30) and forms the end section of the pump housing for the vane pump.
