Abstract

A valve assembly for influencing operating fluid flows in a motorized vehicle, where the valve assembly includes:A valve housing with a main housing body and a housing lid,A fluid line arrangement with at least two fluid lines,A valve body configured as tapering along an actuating axis which is accommodated rotatably about the actuating axis between at least two fluid lines of the fluid line arrangement in such a way that through rotation of the valve body about the actuating axis, a flow-connection state of the at least two fluid lines proceeding in different spatial regions with each other is modifiable, andA pre-tensioning means arranged between the housing lid and the valve body which loads the valve body along the actuating axis,wherein it is provided that between the valve body and the main housing body there is arranged a guide shell surrounding the valve body, where the valve body is loaded through the pre-tensioning means towards the guide shell along a first pre-tensioning force path, where the guide shell is loaded through the housing lid towards the main housing body along a second pre-tensioning force path.

16 . A valve assembly for influencing operating fluid flows, in particular cooling fluid flows, especially preferably cooling liquid flows, in a motorized vehicle, where the valve assembly comprises:
a valve housing with a main housing body and a housing lid connected with the main housing body, where in the valve housing there is configured a valve body accommodating space which is enclosed by the main housing body and the housing lid, a fluid line arrangement with at least two fluid lines, which starting from the valve body accommodating space proceed in different spatial regions, a valve body configured as tapering along an actuating axis, which is accommodated rotatably about the actuating axis in the valve body accommodating space between at least two fluid lines of the fluid line arrangement proceeding in different spatial regions in such a way that through rotation of the valve body about the actuating axis a flow-connection state of the at least two fluid lines of the fluid line arrangement proceeding in different spatial regions with each other is modifiable, and a pre-tensioning means which loads the valve body along the actuating axis in the tapering direction, where the pre-tensioning means is arranged between the housing lid and the valve body arranged is,
wherein between the valve body and the main housing body there is arranged a guide shell which surrounds the valve body, where the valve body is loaded through the pre-tensioning means along a first pre-tensioning force path towards the guide shell, where the guide shell is loaded through the housing lid towards the main housing body along a second pre-tensioning force path different from the first pre-tensioning force path.

17 . The valve assembly according to claim 16 , wherein the guide shell is supported physically at the housing lid directly or indirectly under interposition of an intermediate component.

18 . The valve assembly according to claim 17 , wherein the guide shell is directly or indirectly in abutting engagement with the housing lid.

19 . The valve assembly according to claim 17 , wherein the guide shell is directly or indirectly in positive-locking engagement with the housing lid.

20 . The valve assembly according to claim 16 , wherein on the side of the guide shell facing away from the valve body there is arranged additionally a shell gasket in order to seal the regions formed by the guide shell of the at least two fluid lines of the fluid line arrangement proceeding in different spatial regions against the main housing body, where the shell gasket is pressure-loaded under force mediation of the guide shell.

21 . The valve assembly according to claim 16 , wherein the position of the housing lid relative to the main housing body determines the pressure loading of the shell gasket through the guide shell.

22 . The valve assembly according to claim 16 , wherein the axial position of the housing lid relative to the main housing body determines the pressure loading of the shell gasket through the guide shell.

23 . The valve assembly according to claim 16 , wherein the position of the housing lid relative to the main housing body determines the loading of the valve body through the pre-tensioning means towards the guide shell.

24 . The valve assembly according to claim 16 , wherein the axial position of the housing lid relative to the main housing body determines the loading of the valve body through the pre-tensioning means towards the guide shell.

25 . The valve assembly according to claim 16 , wherein the housing lid is firmly bonded relative to the main housing body.

26 . The valve assembly according to claim 16 , wherein the housing lid is at least one of fused or welded to the main housing body.

27 . The valve assembly according to claim 16 , wherein the housing lid is joined with the main housing body by positive locking.

28 . The valve assembly according to claim 16 , wherein the housing lid is joined with the main housing body with a catch or snap-fit.

29 . The valve assembly according to claim 16 , wherein in the first pre-tensioning force path between the housing lid and the pre-tensioning means and/or between the pre-tensioning means and the valve body there is arranged a bearing component.

30 . The valve assembly according to claim 29 , wherein the bearing component is formed at least section-wise or completely from an elastomer.

31 . The valve assembly according to claim 16 , wherein between the valve body and the guide shell there is arranged an abutment component immovably relative to the guide shell.

32 . The valve assembly according to claim 16 , wherein at least one section of the main housing body which encloses the valve body accommodating space is configured in one piece.

33 . The valve assembly according to claim 16 , wherein a section of the main housing body which encloses the valve body accommodating space is configured in at least two parts.

34 . The valve assembly according to claim 16 , wherein the main housing body is formed from a section of a duct component in which fluid lines of the fluid line arrangement are configured.

35 . The valve assembly according to claim 33 , wherein the section of the main housing body which encloses the valve body accommodating space exhibits an upper shell and a lower shell connected with the upper shell, where the housing lid is connected with the upper shell and/or with the lower shell.
