Gear pump, particularly oil pump for internal combustion engine, has control valve, which is additionally connected with outlet over throttle in position of piston for connecting control fluid in fluid conducting manner

摘要

The gear pump has an output changing displacement unit (20), which is arranged displaceable between a control chamber (22) and another control chamber (24). A control valve is connected with the gear pump, such that the control valve is connected with a control fluid in a pressurized and fluid conducting manner in a position of a piston. The control valve is additionally connected with an outlet over a throttle in the position of the piston for connecting the control fluid in a fluid conducting manner.
