Abstract

Druckregeleinheit (1), insbesondere für eine Brennkraftmaschine mit einer Pumpe (2) mit einer Förderdruck- (2a) und einer Saugseite (2b) für eine Schmiermittelumlaufschmierung (3) mit zumindest einem Schmiermittelverbraucher (4), wobei die Druckregeleinheit (1) im wesentlichen aus einem in einem Gehäuse (5) schiebebeweglich angeordneten Steuerkolben (6) besteht, wobei der Steuerkolben (6) und das Gehäuse (5) eine Bypasskammer (7) und eine verschließbare Bypassöffnung (7a) bilden, die schmiermittelführend mit der Förderdruckseite (2a) verbunden und mit der Saugseite (2b) verbindbar ist, wobei der Steuerkolben (6) von dem Förderdruck über eine zweite Steuerfläche (6b) gegen eine Federkraft eines Federelementes (8) verschiebbar ist, wobei der Steuerkolben (6) auf der dem Federelement (8) abgewandten Seite eine dritte Steuerfläche (6c) aufweist, die mit dem Gehäuse (5) eine dritte Steuerkammer (10) bildet, wobei die zweite Steuerkammer (9) mit der Förderdruckseite (2a) und die dritte Steuerkammer (10) mit der Schmiermittelumlaufschmierung (3) in Förderrichtung nach dem Schmiermittelverbraucher (4) schmiermittelführend verbunden ist.Pressure control unit (1), in particular for an internal combustion engine having a pump (2) with a delivery pressure (2a) and a suction side (2b) for a lubricant circulation lubrication (3) with at least one lubricant consumer (4), wherein the pressure control unit (1) substantially a control piston (6) arranged so as to move in a housing (5) so that the control piston (6) and the housing (5) form a bypass chamber (7) and a closable bypass opening (7a), which carries the lubricant with the delivery pressure side (2a) connected and with the suction side (2b) is connectable, wherein the control piston (6) of the delivery pressure via a second control surface (6b) against a spring force of a spring element (8) is displaceable, wherein the control piston (6) on the said spring element (8 ) side facing away from a third control surface (6c) which forms a third control chamber (10) with the housing (5), wherein the second control chamber (9) with the delivery pressure side (2a) and d The third control chamber (10) with the lubricant circulation lubrication (3) in the conveying direction after the lubricant consumer (4) is lubricant-leading connected.

Durch die erfindungsgemäße Ausgestaltung der Druckregeleinheit können zusätzliche Stellelemente zur schmiermitteltemperaturabhängigen Druckregelung eingespart werden.
