摘要
A torque control crescent oil pump, having low parasitic loss and rapid pressure transient response, and a method for controlling oil flow within the pump, are provided. In one embodiment, the crescent oil pump comprises a housing, toothed annular gears cooperatively rotating about preferably offset first and second axes, and a crescent body. The crescent body is adapted to move from a first position to a second position. In the first position, the crescent body is adapted to form a seal between the annular gears. In the second position, the crescent body is positioned so that it does not form a seal between the annular gears. In another embodiment, an actuating device moves the crescent body from the first position to the second position.
