Features oil pump gear is reliable, simple structure, easy to manufacture and high pressure oil pump, so widely adopted. When the engine is working, gear driven oil pump drive gear on the camshaft, secured to the pinion shaft pinion gear to rotate, thereby driving the driven gear rotates in the opposite direction of the oil from the inlet chamber along backlash and pump the oil to the chamber wall. Thus, the inlet chamber is formed at low pressure and create a suction to the oil sump of the oil sucked into the chamber. Since the main, driven gear constantly rotating, oil will continue to be pumped to the required site.
