Abstract: The invention specifies a hydraulic vane-type machine (1) having a stator (2) and having a rotor (3) which has multiple vanes (4), each of which vanes is radially displaceable in a guide (5) in the rotor (3), bears against an inner circumference (6) of the stator (2), and, together with the rotor (3), the stator (2) and in each case one side wall (7) at each axial end of the rotor (3), delimits working chambers whose volumes vary in the event of a rotation of the rotor (3) relative to the stator (2). It is sought to obtain a certain degree of freedom for the design of the inner circumference. For this purpose, it is provided that each vane (4) has, on its radially inner side, an abutment surface (17) which bears radially at the outside against a cam disk (15).

Abstract: A vane pump (1) is disclosed comprising a housing (2) having a stator bore, a rotor (4) being rotatably mounted within said stator bore, and having a number of vanes (5) slidably mounted in said rotor (4) in radial direction of said rotor (4), an inlet (11) and an outlet (12). Such a vane pump should have a good efficiency. To this end said inlet (11) opens in an axial end wall of said stator bore (3) and said outlet (12) is connected to an outflow area formed in a circumferential wall (3) of said stator bore.

Abstract: The invention concerns a valve arrangement (7) comprising a flow path (11) connecting an inlet (9) and an outlet (10), a closing means (12) arranged in said flow path (11), a resetting means and a first pressure in a first pressure chamber (14) acting in a closing direction on said closing means (12), a pressure of said outlet (10) and a second pressure in a second pressure chamber (18) corresponding to a pressure of said inlet (9) when said closing means (12) is closed acting in opening direction on said closing means (12), said first pressure chamber (14) being connectable to the outlet (10) via an auxiliary valve (13). It is intended to keep small a pressure pulse when opening the valve arrangement (7). This is achieved in that the closing means (12) having a first opening state (A) and a second opening state (B), a flow resistance of said closing means (12) in said first opening state (A) being larger than a flow resistance of said closing means in said second opening state (B).

Abstract: The invention concerns a vane cell machine with a stator and a rotor having radially displaceable vanes arranged in guides, said vanes bearing on an inside of the stator and bordering, together with the rotor, the stator and a side wall, work chambers at each axial end of the rotor. It is endeavoured to provide a vane cell machine that has a good internal tightness, in which the wear is still kept small. For this purpose, in a radially internal area the side wall comprises an insert that is axially movable in the side wall and has a pressure application surface axially inside and axially outside.
