A high pressure pump is disclosed. The high pressure pump comprises a compression chamber having an inlet for connecting to a fluid supply to intake a fluid, and an outlet, an inlet check valve between the compression chamber and the inlet, a digital inlet valve between the compression chamber and the inlet check valve, a variable volume chamber connected to the compression chamber through a manifold and the digital inlet valve, and a plunger or piston configured to compress the fluid in the compression chamber and the variable volume chamber.

High pressure pump and method for compressing a fluid

A fuel injection system for an engine of a vehicle may include an injector nozzle mounted in an injector bore formed in a cylinder head of the engine, wherein a tip portion of the injector nozzle is protrudingly formed into a combustion chamber, and having a positioning system configured to adjust an axial position of the injector nozzle in the injector bore. The invention further provides a method of operating the fuel injection system.

A high-pressure pump arrangement for a combustion engine comprises a high-pressure pump with the first flange, a pump guidance with a second flange. The high-pressure pump is at least partially arranged in the pump guidance and the pump guidance is arranged in the combustion chamber. A first thermally insulating layer is at least partially arranged between the first flange and the second flange.

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.
