Closing member for a ring valve

A closing reed for mounting on a valve seat having a plurality of concentrically arranged portways, comprising:

• a plurality of flexible ring members extending in radial spaced concentric relationship over an angle less than 360.degree. for controlling the flow of fluid through the valve portways and being separated by concentrically extending slits between adjoining ring members;
• the outermost one of said flexible ring members including two substantially diametrically positioned mounting holes and being continuous therebetween;
• at least one radially extending web member interconnecting said plurality of concentric ring members and said outermost flexible ring member;
• and
• additional web members interconnecting said plurality of flexible ring members at the respective end portions thereof remote from said at least one radially extending web member.

A combined valve assembly for compressors including suction and delivery valve sections having two disc-shaped valve members provided with concentrically arranged portways for the flow of fluid therethrough and located in spaced relation one above the other, a spacer disc consisting of resilient material such as sealing material and provided with two recesses;

• a valve reed being arranged within each of the recesses and comprising:
• a first flexible ring portion extending over an angle less than 360.degree. and being fastened by end portions thereof between the spacer disc and one of the two disc-shaped valve members;
• a plurality of flexible ring portions extending in radial spaced concentric relationship to the first flexible ring portion and being interconnected by at least one radially extending web member starting from the flexible part of the first flexible ring portion extending between the two fastened end portions thereof;
• additional radially extending web members interconnecting at least some of said plurality of concentric ring members and said outermost ring member, said additional web members being respectively located at intermediate positions on the circumference of said outermost ring member between said mounting holes;
• and
• the valve reed positioned in the first recess controlling the flow of fluid through the portways of the suction valve, and the valve reed positioned in the second recess controlling the flow of fluid through the portways of the delivery valve.
