摘要

The engine (10) has an exhaust chamber (44) arranged opposite to a control chamber (42), which is defined by a cam ring (32) and a housing outer wall (24). An exhaust opening (56) passes through the housing wall and connects the exhaust chamber to the fluid flow along a rotating surface. A fin (60) blocks fluid flowing through the exhaust chamber. The fin converts the movement of the fluid flow into a static fluid pressure within the exhaust chamber, which pushes the cam ring into a direction increasing oil flow so that the pump outlet oil flow is increased when increasing the engine speed.
