Abstract

A valve plate includes a cooling medium duct for a compressor used for generating compressed air. From the perspective of a piston chamber of the compressor, at least part of the cooling medium duct extends between the piston chamber and an air discharge valve that is arranged in the valve plate. A method for cooling compressed air in a valve plate of a compressor is also provided.

Claims (23)

1. A valve plate for a compressor having a piston chamber, the valve plate comprising:

an air outlet valve arranged in the valve plate; a coolant duct extending, at least partially between the piston chamber and the air outlet valve when viewed from the piston chamber of the compressor; and

an air guide having a meandering course in a body of the valve plate, wherein

the air guide is arranged in a plane of the valve plate, and

the coolant duct operates to cool compressed air generated by the

compressor as compressed air from the piston chamber passes through the air guide.

2. The valve plate according to claim 1 , wherein the coolant duct has an at least partially meandering course in a base of the valve plate.

3. The valve plate according to claim 1 , wherein more than one air outlet valve is arranged in a body of the valve plate.

4. A compressor, comprising: a piston chamber; a valve plate having a coolant duct, the coolant duct running at least partially between the piston chamber and an air outlet valve arranged in the valve plate viewed from the piston chamber of the compressor, and

an air guide having a meandering course in a body of the valve plate, wherein

the air guide is arranged in a plane of the valve plate, and

the coolant duct operates to cool compressed air generated by the

compressor as compressed air from the piston chamber passes through the air guide.

5. The compressor according to claim 4 , wherein the coolant duct is arranged at least partially with a meandering course in a base of the valve plate.

6. The compressor according to claim 5 , wherein more than one outlet valve is arranged in the body of the valve plate.

7. A method for cooling compressed air in a valve plate of a compressor, the method comprising the acts of:

producing compressed air via a piston chamber of the compressor; and

cooling said compressed air via a coolant conducted through a coolant duct at least partially between the piston chamber and an air outlet valve arranged in the valve plate when viewed from the piston chamber of the compressor,

wherein the act of producing compressed air further comprises the act of conducting the compressed air along a meandering course in a body of the valve plate, and

wherein an air guide is arranged in a plane of the valve plate.

8. The method according to claim 7 , wherein the cooling act further comprises the act of conducting the coolant along a meandering course in a base of the valve plate.

9. The method according to claim 7 , wherein the compressed air flows into the body of the valve plate through a plurality of air outlet valves.

10. The method according to claim 8 , wherein the compressed air flows into the body of the valve plate through a plurality of air outlet valves.
