摘要： A diaphragm for a flush valve is made of molded rubber with a plastic insert for strengthening the diaphragm. The insert includes reinforcing means located at the points where the diaphragm is attached to the valve parts. There is also a plurality of spaced, rigid sections placed between the points of attachment. Connecting means are provided for connecting the reinforcing means and the rigid sections together. The connecting means is arranged to permit flexibility of the diaphragm in two planes. Thus, the diaphragm is permitted to flex both in the plane of the diaphragm and perpendicular to the diaphragm.

摘要： A discharge valve retainer for a compressor with at least two arcuately-shaped, annular segments which segments are joined together. By joining the annular segments together, a retainer structure having a very rigid central portion results, thereby reducing stress and fatigue of the retainer. The discharge ports are arranged in an annular fashion and the suction ports are disposed radially inside the annularly arranged discharge ports.
