Abstract
An oil filter module (10) has a connection for a filter element (14) and an oil-coolant heat exchanger (12). Arranged in a housing (26, 42) is a bypass line (20) for bypassing the oil-coolant heat exchanger (12). The bypass line (20) has a valve chamber (22) with a thermostat unit (24). The thermostat unit (24) controls an oil flow through the bypass line (20) according to a temperature of the oil. The housing is made up at least of a valve housing part (26) and a heat exchanger housing part (42). The valve chamber (22) is arranged in the valve housing part (26). A base plate (40) of the heat exchanger housing part (42) closes the valve chamber (22) lengthwise.
Claims10
An oil filter module (10) of a filter for oil, comprising:
- a connector for a filter element (14);
- an oil-coolant heat exchanger (12) controlling temperature of supplied oil;
- a housing (26, 42) in which a bypass line (20) for bypassing the oil-coolant heat exchanger (12) is arranged, the housing including a valve chamber (22) with a thermostat unit (24);
- wherein the thermostat unit (24) controls oil flow through the bypass line (20) depending on the temperature of the oil;
- wherein the housing is comprises
- at least a valve housing part (26);
- and
- a heat exchanger housing part (42);
- wherein the valve chamber (22) is arranged in the valve housing part (26);
- wherein the valve housing part (26) includes a control chamber (36);
- wherein a control unit (62) arranged within the control chamber (36), the control unit (62) including a guide pin (64) extending outwardly away from the control unit (62);
- wherein the guide pin (64) is inserted into a guide pin receptacle in the valve housing (26) and abuting against a stop;
- wherein a base plate (40) of the heat exchanger housing part (42) closes off the valve chamber (22) along a longitudinal side.
