Abstract
The present invention relates to a high pressure fuel pump comprising an inlet channel in connection with a first chamber, through which inlet channel fuel is led to the first chamber, a second chamber arranged in connection with the first chamber, an outlet valve arranged in connection with the second chamber and an inlet valve comprising a piston, with a first end section and a second end section. The piston is moveably arranged with the first end section in a third chamber, and the second end section is moveably arranged between the first chamber and the second chamber. A press element is arranged to act on the piston with a mechanic force, so that the piston strives to be positioned with the second end section closing the connection between the first chamber and the second chamber. The inlet valve is in a closed state and may be controlled via an electromagnetic unit.
