ABSTRACT:
Snubbers and methods and apparatus for the in-place testing thereof are disclosed. The snubbers include a manifold between the hydraulic cylinder and each of the two control valves fastened thereto whereby for test purposes the control valves and hydraulic cylinder may be isolated from each other and coupled to a test machine for the independent testing thereof. Isolation of the control valves from the hydraulic cylinder allows separate testing of the control valves for lockup and bleed, and isolation of the hydraulic cylinder allows the testing of the cylinder for leakage and breakaway. Various embodiments are disclosed.
