Abstract: An apparatus for increasing the longevity of reed valves. Machines such as automotive air conditioning compressors operate with a centrally-located rotating shaft that requires lubricant seals. Assembly of such machines with access for installation of one or more shaft seals commonly dictates an annular cavity between the shaft outer diameter and the housing inner diameter. For reed valves radially deployed around the shaft, the result is an anchor point that, coupled with the commercial need for minimum overall machine diameter, restricts the allowable length of the valve reeds. A cylindrical insert that fits in the annular cavity provides for an anchor point close to the shaft, and a clamping device that anchors the reed to a retainer and its valve plate permits the use of longer reeds that offer enhanced life.
