Title: Fluid operable actuator
IPC: F15B15/26
Filed: 1971-12-23
Abstract: 1345009 Fluid operated actuators TOYOOKI KOGYO K K 23 Dec 1971 [28 Dec 1970 30 Jan 1971] 60096/71 Heading F1D When a fluid operated actuator comprising a piston 4 slidable in a cylinder 1 is unpressurised, brake bands 15 mounted in a groove 16 in the piston frictionally engages the cylinder 1 to lock the piston against movement. If pressure is applied to one or other of the cylinder chambers 23a, 23b, plungers 12 are displaced from their neutral positions (shown) against the action of centralling springs Fig.3, (not shown), to release the brake bands. Movement of the plungers 12 is effected by the pressure acting on one or other side of a pressure plate 11, the pressure being admitted through a passageway 24 to a chamber 25 for movement of the plate to the left. In an embodiment (not shown), a rack (26) on one of the plungers 12 rotates a pinion on a shaft having an elliptical cam for expanding a single brake band. As shown a 14a, 14b, 14c on each cam profile plunger causes radial displacement of a ball 17 to expand a respective band 15.
