Abstract
This invention relates to a hydraulic-oil feeding device for a hydraulically operated injection timing mechanism disposed on the injection pump shaft of an injection pump for air-compressing injection-type internal-combustion engines. A pump shaft is partially disposed in an injection pump housing. A feeding member leads from the pump housing to the pump shaft. An arrangement of bores forms a passage or transition between the feeding member and the injection timing mechanism. The passage is interrupted during each injection process, and the passage is open in between injection processes.
