- Heat exchanger defined at the intermediate piece. Regardless of the variant chosen in each case, however, no complicated fastening technology, such as, for example, a bayonet closure, is required for fixing the valve in the receiving channel in the liquid filter module according to the invention. Rather, this can, in particular in the case of the aforementioned sleeve, already occupied existing components of the liquid filter module with an additional function and used to secure the valve in the receiving channel. This reduces particularly a constructive effort and also the
- the valve has a housing with a wax expansion element arranged therein, a spring and a working piston.
- the spring serves to return the working piston, while the wax expansion element causes temperature-dependent adjustment of the working piston against the spring force.
- a bimetal or a shape memory alloy can be used instead of the Wachsdehnelements.
- the housing has a peripheral annular groove in which an O-ring seal is arranged, via which the valve is liquid-tight in the
- Recording channel is recorded.
- a reliable sealing of the valve can be achieved, so that can be dispensed with in this case on separate cover for tight closure of the receiving channel. This allows the variety of parts and the
- the housing expediently has on one end side a guide contour, in particular a transverse groove, into which the securing element at least partially engages.
- a guide contour in particular a transverse groove, into which the securing element at least partially engages.
- this guide contour which may be formed, for example, as the end face of the housing transverse groove, an angular position installation of the valve, in particular the bypass valve, can be forced in the receiving channel, as well as a reliable fixation of the valve in the
- the sleeve is at most as long as the height of the intermediate piece.
- the aforementioned sleeves are provided, the length of which corresponds substantially to the height of the intermediate piece and thereby enables a fixation of the liquid filter module to the internal combustion engine without defective pinching of the intermediate piece.
- the length of the sleeve is slightly smaller than the height of the intermediate piece in order to apply a predefined tension on the intermediate piece can.
- the sleeve is the same length or longer as the height of the intermediate piece.
- the sleeve can additionally as a positioning aid for an additional unit, preferably a heat exchanger, a
- the heat exchanger has a base plate with a arranged at an edge of the base plate passage opening, with the mounted liquid filter module with the channel in the intermediate piece is aligned.
- the sleeve and the guided therein fixing screw for fixing the liquid filter module to the
- a positioning pin securing element which serves exclusively to determine a defined relative position of the heat exchanger with respect to the intermediate piece.
- a positioning element may additionally be provided, which on the one hand engages in a recess on the heat exchanger and on the other hand in a recess on the intermediate piece and defines a relative position of the heat exchanger on the intermediate piece. Together with the positioning pin or the sleeve can be forced with the positioning an unambiguous relative position.
- Adapter made of plastic, in particular as a plastic injection molded part formed.
- a design of the intermediate piece as a plastic injection molded part allows on the one hand a cost-effective and on the other hand a high-quality production of the intermediate piece.
- FIG. 1 shows a liquid filter module according to the invention with an intermediate piece and a sleeve provided for fixing a valve
- an inventive liquid filter module in particular an oil filter module, has an intermediate piece 2 on which a
- Heat exchanger 3 and a filter device 4 are arranged.
- Adapter 2 is made of plastic, especially as
- plastic injection molded part formed in the intermediate piece 2 there are at least one liquid channel 5 (see also FIGS. 2 and 4) and a transversal one
- Receiving channel 6 for receiving a valve 7 is provided.
- a receiving channel 6 crossing channel 8 is provided, in which a securing element 9 is arranged.
- the valve 7 has a housing 14 with a arranged therein
- the housing 14 has a peripheral annular groove 15 in which an O-ring seal 16 is arranged, via which the valve 7 is received in the receiving channel 6 in a liquid-tight manner.
- a guide contour 17 is Provided as extending in the transverse direction groove into which the securing element 9 in the assembled state at least partially engages, as can be seen well, for example, in FIG.
- the securing element 9 may, for example, be designed as a sleeve 18, through which a screw 19 for fastening the liquid filter module 1 to the internal combustion engine 13 is guided.
- a screw 19 for fastening the liquid filter module 1 to the internal combustion engine 13 is guided.
- the sleeve 18 is at most as long as the height of the intermediate piece 2, usually slightly shorter, whereby a predefined Anschraubkraft and a predefined compressive force can be ensured on the spacer 2.
- the sleeve 18 may be the same length or longer as the height of the intermediate piece 2. In a supernatant of the sleeve 18 over the height of the
