ABSTRACT:
A pressure valve is proposed herein which is built into the injection pump, its valve closing body being guided in a valve carrier, and arranged to open in the supply direction of the fuel, counter to the force of a restoring spring. A check valve is built into the pressure valve, its valve seat carrier being secured to the valve closing body and its movable valve closing member is arranged to open counter to the supply direction of the fuel via a spring supported on the base of the valve closing body. For axially securing the valve seat carrier on the valve closing body, the restoring spring simultaneously engages the valve seat carrier. As a result, the satisfactory functioning of the check valve is assured.
