Valve seat
A valve with a valve seat includes an inner path providing a first flow channel adapted to be in contact with a first chamber of the valve, the valve seat including at least one outer path also adapted to be in contact with the first chamber, the valve seat further including an area facing a sealing area of the valve, the area being adapted to be in connection with a second chamber, the area having an inner sealing edge and an outer sealing edge, and wherein the valve seat is adapted to allow for a flow between the first chamber and the second chamber when the valve is in an open position, where the flow in the inner path and the at least one outer path flow through the area in contact with the second chamber via the inner sealing edge and the outer sealing edge, respectively.
1. A valve seat for use in a valve, the valve seat comprising
an inner path through a single body and adapted to be in fluid communication with a first chamber of the valve,
at least one outer path also through the single body and adapted to be in fluid communication with the first chamber, and
an intermediate path through the single body and that bounds an area configured to face a sealing area of the valve, said intermediate path being adapted to be in fluid communication with a second chamber, said area being bounded by an inner sealing edge and an outer sealing edge,
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 flows through said area via the inner sealing edge and the outer sealing edge, respectively.
2. The valve seat according to claim 1 , wherein the intermediate path comprises a recess in the single body, and a top section of the recess forms the area facing the sealing area 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 coplanar.
6. The valve seat according to claim 1 , wherein the at least one outer path comprises at least two outer paths.
7. The valve seat according to claim 1 , wherein the inner path is in fluid communication with the first chamber by way of at least two supply channels.
8. A valve comprising the 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 , wherein the intermediate path comprises a recess in the single body, and a top section of the recess forms the area facing the sealing area of the valve, and
the valve comprises the sealing area, which is 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.
