| description | The valve assembly for a rotary compressor includes an elongated valve member which rests on pads on each side of the valve seat and includes an intermediate sealing section normally sealing against the valve seat. An elongated valve spring biases the sealing section toward engagement with the valve seat. An elongated spring backer sits on one end of the valve spring and the other end of the valve member. One end of each of the valve member, valve spring and spring backer are bolted to the compressor end plate. The other end of the spring backer permits the corresponding end of the valve member to slide along the end plate as the valve member moves between its open and closed positions, while restraining the end of the valve member from moving away from the end plate. A backer support, positioned between the spring backer and the head of the bolt, spreads the clamping force and defines a line about which the valve member and valve spring flex. |
