Abstract

1336868 Hydraulic piston-cylinder pipe supports CARPENTER & PATERSON Ltd 16 Dec 1971 [16 Dec 1970] 59655/70 Heading F2S An hydraulic piston-cylinder unit for supporting a pipe has a piston-rod 9 which extends throughout the cylinder and the space in the cylinder on each side of the piston 7 is connected through respective normally open spring loaded shut-off valves 21 to a reservoir 18, one or other of the valves (depending on the direction of piston movement) closing if the piston reaches a certain speed. The valve element 21 is held off its seat by a spring 22 and is formed with flats 23 which allow liquid to flow past in this open position. A pressure relief valve (Fig. 3, not shown) and an adjustable needle valve (Fig. 4, not shown) in parallel with the valve 21 are provided at both ends of the cylinder. The liquid in the reservoir may be acted on by gravity alone, or air under pressure, instead of by spring 35.
