The oil pump is a lightweight and compact pump, and there are three major categories: in-line, dispensing, and monolithic. The oil pump needs a power source to operate, and the camshaft at the lower part of it is driven by the engine crankshaft gear.
The oil pump proposes an oil pump with an aluminum-containing casing and a movable moulding part arranged in the casing, wherein the movable moulding part is at least partially made of a material that can be sintered and contains at least one austenitic iron-based alloy, and the moulding part made of a sinterable material has a coefficient of thermal expansion of at least 60% of the thermal expansion coefficient of the casing.
