Controller for hydraulic pump i.e. external tooth gear-control oil pump, for lubricating oil supply of internal combustion engine, has regulator producing control pressure from delivery pressure of hydraulic pump

摘要

The controller has an adjustment device changing delivery rate of a hydraulic pump, and a regulator (17) producing control pressure from a delivery pressure of the hydraulic pump, where the delivery pressure is fed over a cable (21). The cable comprises a filter (22), where the regulator is arranged on a crank pin. The regulator is impinged on pressure pistons effecting oil pressure of a pressure chamber of a pump housing.
