Abstract
Abstract A closing plate for a ring valve, in particular a suction or pressure valve of a piston compressor, which is intended to be arranged on a valve seat with arcuate-shaped through-flow passages and comprises at least one concentric ring and at least one concentric sectioned ring which control the through-flow passages, and at least one concentric ring and at least one concentric sectioned ring are connected with each other through radial arms. One of the rings is continuous and adapted to be clamped on the valve seat at at least two points, while at least one other ring is split by radial slits between the radial arms to form the at least one concentric sectioned ring.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
144 words
A closing plate for a ring valve mountable on a valve seat with through-flow passages, comprising: at least one concentric plate ring and at least one radially spaced concentric sectioned plate ring for controlling the through-flow passages; radially extending arms interconnecting said at least one concentric ring and said at least one radially spaced concentric sectioned plate ring; one of said at least one concentric plate ring being continuous and said at least one sectioned ring being separated by radial slits; said at least one continuous ring including spaced points for mounting on said valve seat with the ring portions between said spaced points being flexible; said radial arms extending from a flexible portion of said at least one continuous ring and passing between said spaced points, said radial arms supporting the ring sections of said at least one sectioned ring separated by slits.
Claim 2
Dependent Claim
144 words
A closing plate for a ring valve mountable on a valve seat with through-flow passages, comprising: at least one concentric plate ring and at least one radially spaced concentric sectioned plate ring for controlling the through-flow passages; radially extending arms interconnecting said at least one concentric ring and said at least one radially spaced concentric sectioned plate ring; one of said at least one concentric plate ring being continuous and said at least one sectioned ring being separated by radial slits; said at least one continuous ring including spaced points for mounting on said valve seat with the ring portions between said spaced points being flexible; said radial arms extending from a flexible portion of said at least one continuous ring and passing between said spaced points, said radial arms supporting the ring sections of said at least one sectioned ring separated by slits.
Claim 3
Dependent Claim
40 words
A closing plate as in claim 1 wherein there are two diametrically opposed spaced points and there are two radial arms extending inwardly from respective points on said at least one continuous ring substantially midway between said two spaced points.
Claim 4
Dependent Claim
56 words
A closing plate as in claim 2 wherein the slits separating at least one of said sectioned ring sections are aligned on the same diameter as said spaced points, said radial arms interconnecting said ring sections extending on a diameter disposed at right angles to the diameter common to the said spaced points and said slits.
Claim 5
Dependent Claim
19 words
A closing plate as in claim 3 further comprising an additional arm extending diametrically between said spaced mounting points.
Claim 6
Dependent Claim
25 words
A closing plate as in claim 4 wherein there are two continuous plate rings and a number of sectioned plate rings separated by radial slits.
Claim 7
Dependent Claim
78 words
A ring valve comprising the closing plate of claim 4 and two valve members arranged one above the other and divided diametrically into two halves to form valve seats and valve cages in a suction valve and a pressure valve, respectively, said closing plate being mounted between said two valve members, said continuous ring and said additional arm being clamped between said two valve members and said additional arm forming a seal between said suction and pressure valves.
Claim 8
Dependent Claim
28 words
A closing plate as in claim 1 wherein said continuous ring is the outermost ring, and there are a number of sectioned plate rings separated by radial slits.
Claim 9
Dependent Claim
27 words
A closing plate as in claim 7 wherein said continuous ring includes bores defining said spaced points for location of the closing plate on the valve seat.
Claim 10
Dependent Claim
21 words
A ring valve comprising a valve seat with a plurality of through-flow passages and a closing plate according to claim 1.
