Abstract
1305347 Shock absorbers; pipe supports; valves GRINNELL CORP 19 April 1971 [25 March 1970 16 Oct 1970] 25225/71 Heading F2P F2S and F2V In an hydraulic piston-and-cylinder shockabsorber for supporting a pipe (22, Fig. 1, not shown), a valve 110, Fig. 7, held open by a spring 120, closes on to a conical seat when the rate of flow from the cylinder 4, Fig. 2, reaches a certain value, there being a second such valve 110a for flow in the opposite direction. When the valve 110 closes due to increased flow from the line 8, the compressible fluid passes via a valve 204 adjusted by a graduated knob. The valve has a V-notch 250 which may be closed off completely or locked by a screw (255) in its adjusted position. The spring pressure 120 is adjusted by a screw 126. The normal flow path is 8, 31, 110, 85, 87, 33 and either 50 to a reservoir 12 or 81a, 87a, 110a, 35, 10. When the valve 110 is closed the path is 8, 31, 208, 229, 250, 206, 210, 35, 10. Similar paths occur in the opposite direction of movement. In a modification, two needle valves replace the valve 204 for separate adjustment of the reverse flows. The valve element 110 has a frusto-conical seating surface and a hexagonal radially outer surface (Fig. 5, not shown).
