Regulatable vane-cell pump with a sealing web curving in an arc

The invention relates to a vane pump (1), in particular a regulatable oil pump for a lubricating system, with a pump housing (2) with at least one housing tank (6) and with a vane rotor (11) disposed in the housing tank (6) mounted so that it can be rotated by means of a drive shaft (10) in the pump...

Beschreibung
Zusammenfassung:	The invention relates to a vane pump (1), in particular a regulatable oil pump for a lubricating system, with a pump housing (2) with at least one housing tank (6) and with a vane rotor (11) disposed in the housing tank (6) mounted so that it can be rotated by means of a drive shaft (10) in the pump housing (2) constituting an axis of rotation (23) which provides a mount for vanes (15) in approximately radially extending fitting slots (14). An adjusting ring (27) is provided enclosing the vane rotor (11) and circumferentially bounding pump cells (26) which, by means of a cylindrical internal wall surface (31), can be displaced between a concentric position with respect to the vane rotor (11) and an eccentric position relative thereto, to which pressured is applied by positioning torques caused by the medium pressure and a positioning mechanism (47) in order to regulate a pressure level.
