Abstract (en)

The regulator (17) has a component for filtering and cooling of hydraulic fluid, where the component is loaded with discharge pressure of a regulated oil pump. An adjusting device adjusts flow rate of the regulated oil pump. The adjusting device is loaded with an oil pressure, and a regulated pressure of the regulator regulates the oil pressure by a spring. The regulator produces an increased regulated pressure either from the oil pressure or from the discharge pressure fed over a connection (21), or from the discharge pressure of the regulated oil pump.

Abstract (de)

Eine Außenzahnrad-Regelölpumpe für die Schmierölversorgung eines einen Ölfilter aufweisenden Verbrennungsmotors weist einen Regler (17,36) auf, der den hohen Förderdruck vor dem Ölfilter (14) für die Regelung des nach dem Ölfilter um dessen Druckverlust geringeren Öldruckes nutzt.
