Claims10
A compressor valve assembly device comprising in combination:
- a compressor valve comprising a flat cylindrical valve seat having at least one flat face and a parallel flat cylindrical valve stop plate having a peripheral flat surface to mate with a peripheral portion of the flat face of the valve seat and a recessed flat surface spaced apart from the flat face of the valve seat forming an interior plate receiving area therebetween, the stop plate having an annular ring receiving groove further recessed below the recessed flat surface of the valve stop plate between the recessed flat surface and the peripheral flat surface, the valve seat and the valve stop plate each having a series of flow ports therethrough to admit a flow of gaseous fluid therethrough;
- a flat cylindrical valve plate positioned adjacent to the valve seat within the interior plate receiving area, the valve plate being movable between the valve seat and the valve stop plate;
- an annular dampening ring positioned within the annular ring receiving area in alignment with the valve plate and at least one spring between the dampening ring and the valve stop plate, so that the at least one spring elevates the dampening ring above the recessed flat surface of the valve stop plate and so that the valve plate contacts the dampening ring when the compressor valve is in use and the dampening ring and the at least one spring dampens the force of the movement of valve plate as the valve plate pushes the dampening ring downward until the valve plate contacts the valve stop plate to cause a soft stop of the valve plate.
