Abstract
A high pressure pump is provided to be used in a fuel feeding system for a vehicle engine and receive a fuel primarily pressurized by a low pressure pump, and secondarily compresses the fuel to increase the pressure of the fuel for supplying the fuel to a fuel injector. The high pressure pump includes a pump body and a camshaft that is rotatably installed in the pump body to be rotated using torque transmitted from an exterior of the pump body. Additionally, a roller bearing rotatably supports the camshaft in the pump body and an inlet port is disposed on the pump body to introduce a primarily pressurized fluid into the pump body. An orifice is configured to supply the fluid to the roller bearing while reducing a pressure of the fluid introduced via the inlet port.
