Abstract

Die Erfindung betrifft ein Schmiermittelsystem (1) mit
- einer hinsichtlich ihrer Förderleistung regelbaren Pumpe (2) zum Fördern eines Schmiermittelstroms,
- einem Schmiermittelreservoir (3),
- einem zu schmierenden Bauteil (4), insbesondere einem Verbrennungsmotor oder einem Getriebe,
- einer zwischen der Pumpe (2) und dem zu schmierenden Bauteil (4) und stromab der Pumpe (2) gelegenen Blende (5) zur Mengenbegrenzung des Schmiermittelstroms, wobei die Blende (5) hinsichtlich ihrer Durchlassmenge und damit einer dort auftretenden Druckdifferenz einstellbar ist,
- einer Regeleinrichtung (6), die zur Regelung der Förderleistung der Pumpe (2) in Abhängigkeit der Druckdifferenz an der Blende (5) ausgebildet ist.

The invention relates to a lubricant system (1) with
a pump (2) controllable with regard to its delivery capacity for conveying a lubricant flow,
a lubricant reservoir (3),
a component (4) to be lubricated, in particular an internal combustion engine or a transmission,
- One between the pump (2) and the component to be lubricated (4) and downstream of the pump (2) located aperture (5) for limiting the amount of lubricant flow, the aperture (5) is adjustable in terms of their passage rate and thus a pressure difference occurring there .
- A control device (6), which is designed to control the delivery rate of the pump (2) in dependence on the pressure difference at the diaphragm (5).
