Description: |
| Abstract:
This invention relates to valve mechanism. The invention is particularly applicable to air valves or the like, and has been found to be specifically advantageous in its adaptation to compressor valve structures.
An object of the invention is to provide a valve in which plates are utilized to close the valve openings and in which the plates are provided with uniform spring pressure having the advantage of distributing the spring pressure to the valve plates substantially uniformly per unit of valve plate area of pressure distribution.
Another object of the invention is to provide a structure in which the valve plates are free from undue and localized wearing.
Claim:
A compressor plate valve having frame means providing a plurality of valve openings and adjacent seats lying substantially in the same plane, a plurality of relatively thin valve plates engageable with said seats to close said openings, a common valve-holding member overlying and bearing against said plates, said member being in the form of an elongated rod extending transversely of the path of movement of the plates and restricted to a path of movement substantially parallel to the movement of said plates, and means urging said member to yieldably hold said plates in closed position. |
