Abstract

The device has a valve piston end (41) including a blind hole (54) extending in an axial direction, where the piston end is opened to a valve control chamber (48). The blind hole extends in an area of a guiding section (39), where the blind hole is formed by a central blind hole. The chamber and the guiding section are provided in a common recess (38) of a housing body. Fuel inlet and outlet channels (50, 49) are started from the recess that has a shape of a straight circular cylinder. The piston end is guided in an axial direction in the guiding section.
