Abstract
Abstract The diaphragm chamber-damping device has a dished shell below the diaphragm which cooperates with a separating wall to form a pair of chambers within the liquid compartment while providing for a flow of fluid between the two chambers. One chamber communicates with an inlet pipe while the other chamber communicates with an outlet pipe so that fluid can be passed through the device.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
144 words
A diaphragm chamber damping device comprising a housing; a diaphragm mounted within said housing to divide the interior of said housing into a gas compartment and a liquid compartment; a shell-like wall mounted in said liquid compartment, said wall having a rim adjacent said housing defining a passage between said rim and said housing and at least one passageway communicating the opposite sides of said wall with each other; first means communicating with said passageway to conduct a flow of fluid from one side of said wall to the opposite side; and second means separated from said first means and communicating with said passage to conduct a flow of fluid from said opposite side of said wall to said one side whereby a flow of fluid can be passed through said fluid compartment from one of said means to the other of said means.
Claim 2
Dependent Claim
144 words
A diaphragm chamber damping device comprising a housing; a diaphragm mounted within said housing to divide the interior of said housing into a gas compartment and a liquid compartment; a shell-like wall mounted in said liquid compartment, said wall having a rim adjacent said housing defining a passage between said rim and said housing and at least one passageway communicating the opposite sides of said wall with each other; first means communicating with said passageway to conduct a flow of fluid from one side of said wall to the opposite side; and second means separated from said first means and communicating with said passage to conduct a flow of fluid from said opposite side of said wall to said one side whereby a flow of fluid can be passed through said fluid compartment from one of said means to the other of said means.
Claim 3
Dependent Claim
28 words
A diaphragm chamber damping device as set forth in claim 1 wherein said housing is formed of two halves releasably secured together with said diaphragm being secured therebetween.
Claim 4
Dependent Claim
36 words
A diaphragm chamber damping device as set forth in claim 1 wherein at least one of said means includes a tubular connecting element secured to said housing in tangential relation to the interior of said housing.
Claim 5
Dependent Claim
39 words
A diaphragm chamber damping device as set forth in claim 1 which further comprises a tubular wall between said housing and said shell-like wall separating first means from said second means and supporting said shell-like wall in said housing.
Claim 6
Dependent Claim
49 words
A diaphragm chamber damping device as set forth in claim 4 wherein said first means includes a central chamber within said tubular wall and communicating with said passageway in said shell-like wall and said second means includes a chamber concentrically surrounding said central chamber and communicating with said passage.
Claim 7
Dependent Claim
22 words
A diaphragm chamber damping device as set forth in claim 1 which further comprises means for monitoring the condition of said diaphragm.
Claim 8
Dependent Claim
27 words
A diaphragm chamber damping device as set forth in claim 6 wherein said monitoring means is a window in said housing for viewing of said diaphragm therethrough.
Claim 9
Dependent Claim
35 words
A diaphragm chamber damping device as set forth in claim 7 wherein said wall is formed as a support wall for said diaphragm in the event of a discharge of liquid from said liquid compartment.
