Abstract

Described is, among other things, a valve with a valve seat comprising an inner path (5) providing a first flow channel adapted to be in contact with a first chamber (11) of the valve, the valve seat (1) comprising at least one outer path (6) also adapted to be in contact with the first chamber (11), the valve seat further comprising an area facing a sealing of the valve, said area adapted to be in connection with a second chamber (12), said area having an inner sealing edge (3) and an outer sealing edge (2), and wherein said valve seat (1) is adapted to allow for a flow between said first chamber (11) and said second chamber (12) when the valve is in an open position, where said flow in said inner path (5) and said at least one outer path (6) flow through said area being in contact with the second chamber via the inner sealing edge (3) and the outer sealing edge (2), respectively.

Claims

1. A valve seat for use in a valve, the valve seat comprising an inner path providing a first flow channel adapted to be in contact with a first chamber of the valve, the valve seat comprising at least one outer path also adapted to be in contact with the first chamber, the valve seat further comprising an area facing a sealing of the valve, said area adapted to be in connection with a second chamber, said area having an inner sealing edge and an outer sealing edge, and wherein said valve seat is adapted to allow for a flow between said first chamber and said second chamber when the valve is in an open position, where said flow in said inner path and said at least one outer path flow through said area being in contact with the second chamber via the inner sealing edge and the outer sealing edge, respectively.

2. The valve seat according to claim 1, comprising a recess, the top section of the recess forming the area facing the sealing of the valve.

3. The valve seat according to claim 1, wherein the inner sealing edge is round.

4. The valve seat according to claim 1, wherein the outer sealing edge is round.

5. The valve seat according to claim 1, wherein the inner sealing edge and the outer sealing edge are located in the same plane.

6. The valve seat according to claim 1, wherein at least two outer paths are provided.

7. The valve seat according to claim 1, wherein the inner path is fed via at least two supply channels.

8. A valve comprising a valve seat according to claim 1.

9. The valve according to claim 8 wherein the valve is an electromagnetic valve.

10. The valve according to claim 8, the valve comprising a sealing adapted to seal the recess when the valve is in a closed position.

11. The valve according to claim 8, wherein the valve is pneumatic.
