摘要

A pump 5 working chamber 9 is filled with fuel via a fuel line 23, 11. To initiate high-pressure delivery from working chamber 9 by a pump piston 5, the fuel line 23, 11 is closed by a hydraulically operated valve member 33 whose closing movement is caused by the pressure rise brought about by closing a solenoid valve 55 in a relief line 53 connected to a pressure medium line 49 having a non-return valve 51. <IMAGE>
