Abstract (en)
[origin: WO2012095272A1] The invention relates to a high-pressure pump in particular for fuel injection in a self-igniting pump cylinder (4), which is covered by a pump cylinder head (3), forming a working chamber (2), wherein a pump piston (5) can be moved in a translational manner in the pump cylinder (4) and the working chamber (2) is connected to a low-pressure fuel system via an intake valve (1), which is arranged in the pump cylinder head (3) and has a spring-loaded valve element, and is connected to a high-pressure fuel system by means of a check valve, which is arranged in the pump cylinder head (3). According to the invention, a high-pressure pump is provided, which is improved in particular with regard to the necessary installation space and also the installation complexity of the intake valve (1). This is achieved in that the return spring (16) which loads the valve element of the intake valve (1) is arranged in the working chamber (2) and surrounding the pump piston (5).
