Abstract

An Regelölpumpen für die Schmierölversorgung von Verbrennungsmotoren wird der Öldruck von einem Regelkolben geregelt. Durch eine von einem Magnetventil in ihrer Wirkung schaltbare Drossel in der Steuerdruckleitung zum Regelkolben kann der Öldruck bei Bedarf auf ein geregelt höheres Öldruckniveau umgeschaltet werden.
