Abstract

A valve comprises a valve housing with at least one fluid port. In the valve housing a valve chamber is formed, in which a closing element axially shiftable by a valve drive is provided, which cooperates with at least one valve seat provided in the valve housing. The valve housing has a first end face to which the valve drive can be coupled, and at least one actuation opening in a second end face of the valve housing opposite to the first end face. The actuation opening extends through the valve housing up to the closing element and is arranged eccentrically in the second end face.

First claim

What is claimed:

1. A valve comprising a valve housing with at least one fluid port, wherein the valve is a cartridge valve, wherein the valve housing is formed rotationally symmetrical, and in the valve housing a valve chamber is formed in which a closing element axially shiftable by a valve drive is provided, wherein the closing element cooperates with at least one valve seat provided in the valve housing, and wherein the valve housing includes a first end face to which the valve drive can be coupled, and at least one actuation opening in a second end face of the valve housing, wherein the second end face is an outer face and is opposite to the first end face, which extends through the valve housing up to the closing element and is arranged eccentrically in the second end face wherein one of the at least one fluid port is centrically arranged on the second end face, which in the closed condition is closed by the closing element, wherein the fluid port centrically arranged on the second end face and the at least one actuation opening run parallel to each other.

2. The valve according to claim 1 , wherein the valve housing includes at least one first flow channel which extends parallel to the shifting direction of the closing element.

3. The valve according to claim 1 , wherein the valve housing includes at least one second flow channel which extends vertically to the shifting direction of the closing element.

4. The valve according to claim 1 , wherein the valve housing comprises an insert element and a valve body which has a receptacle in which the insert element is inserted.

5. The valve according to claim 2 , wherein the valve housing comprises an insert element and a valve body which has a receptacle in which the insert element is inserted, and wherein the at least one first flow channel is formed in the insert element.

6. The valve according to claim 3 , wherein the valve housing comprises an insert element and a valve body which has a receptacle in which the insert element is inserted, and wherein the at least one second flow channel is formed in the valve body.

7. The valve according to claim 4 , wherein the at least one actuation opening is provided in the insert element and extends up to the valve chamber.

8. The valve according to claim 1 , wherein the closing element includes a first portion and a second portion, wherein the first portion is formed centrally and symmetrically and can contact the valve seat.

9. The valve according to claim 8 , wherein the first portion of the closing element is formed of a first material and the second portion of the closing element is formed of a second material.

10. The valve according to claim 1 , wherein the closing element includes at least one coupling element via which the valve drive can drive the closing element, in order to shift the closing element.

11. The valve according to claim 10 , wherein a plurality of coupling elements are provided which are arranged symmetrically distributed on a surface of the closing element facing the valve drive and vertically protrude from this surface.

12. The valve according to claim 1 , wherein two valve seats are provided, between which the closing element is axially shiftably arranged.

13. The valve according to claim 12 , wherein the valve seats are arranged opposite each other in the valve chamber.

14. The valve according to claim 1 , wherein the closing element is pretensioned into a starting position via a spring element.

15. The valve according to claim 14 , wherein the closing element is urged against the valve drive.

16. The valve according to claim 1 , wherein the valve drive is coupled with the closing element.

17. The valve according to claim 16 , wherein the valve drive is an electromagnetic drive which comprises a coil and a movable armature which cooperates with the closing element.

18. The valve according to claim 1 , wherein the valve has a diameter between 2 mm and 15 mm.

19. A valve assembly, comprising a valve and a receiving body, which valve is a cartridge valve, wherein the valve comprises a valve housing with at least one fluid port, wherein the valve housing is formed rotationally symmetrical, and in the valve housing a valve chamber is formed in which a closing element axially shiftable by a valve drive is provided, wherein the closing element cooperates with at least one valve seat provided in the valve housing, and wherein the valve housing includes a first end face to which the valve drive can be coupled, and at least one actuation opening in a second end face of the valve housing, wherein the second end face is an outer face and is opposite to the first end face, which extends through the valve housing up to the closing element and is arranged eccentrically in the second end face, wherein one of the at least one fluid port is centrically arranged on the second end face, which in the closed condition is closed by the closing element, and wherein the receiving body accommodates a valve, includes a receiving opening for the valve as well as the fluid port centrically arranged on the second end face, wherein the receiving body has a combined alignment and actuation opening which in the aligned condition of the valve within the receiving opening is aligned with the actuation opening of the valve.

20. A valve comprising a valve housing with at least one fluid port, wherein the valve is a cartridge valve, wherein the valve housing is formed rotationally symmetrical, and in the valve housing a valve chamber is formed in which a closing element axially shiftable by a valve drive is provided, wherein the closing element cooperates with at least one valve seat provided in the valve housing, and wherein the valve housing includes a first end face to which the valve drive can be coupled, and at least one actuation opening in a second end face of the valve housing, wherein the second end face is an outer face and is opposite to the first end face, which extends through the valve housing up to the closing element and is arranged eccentrically in the second end face wherein at least one of the at least one actuation opening is an alignment opening via which the valve is rotatory aligned by introducing an alignment pin from below through the alignment opening when the valve is inserted in a receiving opening of a receiving body.
