External toothing pinion-type control oil pump for lubrication of combustion engines, has intermeshing feed pinions with axially displaceable unit

摘要

A control oil pump with adjustable feed quality has a suction duct (20) for in-feed of oil and a pressure duct (22) for take-off of oil, and has at least two intermeshing feed pinions (4,5) with an axially displaceable unit. The bypass connection for oil feed is designed as at least one bypass boring (15) running through the pressure piston, the boring (15) connecting the pressure channel (22) to the suction channel (20) for minimal feed quantity.
