Abstract

A seal assembly for use in a fluid valve includes: an actuatable valve body configured to open and close at least one connection of the fluid valve; at least one seal configured to sealingly abut against the valve body at one side of the valve body and to sealingly abut against a valve housing of the fluid valve at another side of the valve body; and at least one elevation from a lateral surface of the valve body integrally formed on the valve body sectionally, the at least one elevation being configured to activate the seal in a closed position of the fluid valve.

First claim

The invention claimed is:

1. A seal assembly ( 2 ) for use in a fluid valve ( 14 ) having a valve housing and at least one connection, the seal assembly ( 2 ) comprising:
an actuatable valve body ( 4 , 5 ) configured to, when installed in the fluid valve, open and close the at least one connection;
at least one seal ( 6 ) configured to:
sealingly abut against the valve body ( 5 ) and, when the at least one seal ( 6 ) and the valve body ( 5 ) are installed in the housing of the fluid valve, to also sealingly abut against the valve housing of the fluid valve; and

at least one elevation ( 8 ) from a lateral surface of the valve body integrally formed on the valve body ( 5 ) sectionally, the at least one elevation ( 8 ) being configured to, when the valve body ( 5 ) is arranged in the housing of the fluid valve, activate the seal ( 6 ) in a closed position of the fluid valve ( 14 ),
wherein the seal ( 6 ) comprises an elastically deformable plastic base part, composed of an elastomer, and further comprises a vulcanized rigid plastic layer, which forms a circular annular closed encircling bead configured to interact with the elevation ( 8 ) with a static and linear and/or areal sealing action.

2. The seal assembly as claimed in claim 1 , wherein the elevation ( 8 ) is integrally formed in a closed encircling manner on the valve body lateral surface.

3. The seal assembly as claimed in claim 2 , wherein the portion ( 5 ) of the valve body ( 4 ) having the elevation ( 8 ) is of cylindrical or spherical form.

4. The seal assembly as claimed in claim 1 , wherein a face side, facing the valve body ( 5 ), of the seal ( 6 ) is set at an angle with respect to a longitudinal direction (X X) of the seal ( 6 ) in a manner corresponding to the shaping of the valve body ( 5 ).

5. The seal assembly as claimed in claim 4 , wherein the face side includes an angle of 45° to 75° with the longitudinal direction (X-X).

6. A fluid valve having the seal assembly ( 2 ) as claimed in claim 1 , the seal assembly ( 2 ) being configured to seal off at least one connection region of the fluid valve.

7. The fluid valve as claimed in claim 6 , wherein the fluid valve comprises a multi-way fluid valve.

8. The fluid valve as claimed in claim 6 , wherein the fluid valve comprises a cooling-water valve.

9. The fluid valve as claimed in claim 6 , wherein the fluid valve comprises a cooling-water valve of a vehicle.
