Abstract
Die parasitäre hydraulische Last an einem Verbrennungsmotor wird während Kaltstarts wesentlich reduziert, indem ein Entlastungsventil verwendet wird, um die Strömung von Hydraulikfluid von einer Hydraulikpumpe zu einer hydraulischen Betätigungseinrichtung, d.h. einer Lastquelle, abzulenken, wobei das Hydraulikfluid zwischen der Hydraulikpumpe und dem Entlastungsventil rezirkuliert wird.
