ABSTRACT:
A distributor injection pump for internal combustion engines includes a high pressure pump for generating fuel injection pressure, a slide valve for defining fuel amounts to be injected and a piezoelectric adjustment member which actuates via a control chamber filled with fuel the slide of the slide valve. To prevent fomation of bubbles in the control chamber a rinsing conduit is provided, connected to the control chamber to rinse the latter. The rinsing conduit includes one portion connected to a fuel supply line and the other portion connected to a fuel return line leading to a fuel container.
