Adjusting device for use in e.g. lubricating oil pump in motor vehicle, has control pressure chambers separately controlled and subjected with pump- or main channel pressure and arranged at circumference of control slide valve

摘要

The device has an inner rotor (2) arranged in a drive shaft (1), and pump chambers arranged between the inner rotor and a control slide valve (4). Control pressure chambers (11) are separately controlled and subjected with pump- or main channel pressure. The control pressure chambers are arranged at circumference of the control slide valve. A suction chamber (12) stays in connection with a suction nodule (14), and is subjected to suction channel pressure. An inset (21) is arranged between the control slide valve or a control sliding arm (6) and a pump housing (3).
