摘要： A lubricant vane pump for providing a pressurized lubricant for an internal combustion engine includes a pump housing, a pump chamber, a shiftable control ring comprising a pressure-relief-valve, a pump rotor, a pretensioning element which pushes the control ring into a high pumping volume position, a control chamber, and a pump outlet cavity fluidically connected to the control chamber. The pump chamber comprises pump compartments which rotate from a charge to discharge zone. The control ring envelops the pump chamber. The pump rotor comprises radially slidable vanes which rotate in the control ring to provide the pump chamber with the pump compartments. A high lubricant pressure in the control chamber moves the control ring into a low pumping volume direction against the pretensioning element. The pressure-relief-valve of the control ring connects or disconnects the control chamber with one of the pump compartments between the charge zone and the discharge zone.

摘要： A lubricant pump comprises a shiftable control ring, a pump rotor rotating in the control ring, a pump outlet, and a pressure control system. The pressure control system comprises a pressure control chamber which pushes the control ring into a high pumping volume direction, an engine pressure input port connected to an engine pressure output port of an engine, a pilot chamber connected to the engine pressure input port which pushes the control ring into a low pumping volume direction, and a pressure control valve which controls a pressure in the pressure control chamber. The pressure control valve comprises a control valve plunger which opens/closes a control port to connect/disconnect the pressure control chamber to the atmospheric. The control valve plunger is fluidically connected to the engine pressure input port so that the control valve plunger is pushed by a lubricant pressure of the engine into an open position.

A high lubricant pressure in the control chamber moves the control ring into a low pumping volume direction against the pretensioning element. The pressure-relief-valve of the control ring connects or disconnects the control chamber with one of the pump compartments between the charge zone and the discharge zone.
