Title: A power assisted hydraulic actuator particularly for vehicle braking systems
IPC: B60T13/24
Filed: 1958-07-22
Abstract: 835,983. Fluid-pressure brakes. BENDIX-WESTINGHOUSE AUTOMOTIVE AIRBRAKE CO. July 22, 1958 [Sept. 13, 1957], No. 23530/58. Class 103 (1). A power-assisted hydraulic brake actuator comprises a cylinder 26 containing a movable element 24 having a hollow sleeve extension 30 projecting into master cylinder 12 and containing a reaction plunger 32 and a control valve plunger 50 controlling the air pressure differential across element 24 and being moved by a manually movable plunger 38 normally spaced from the valve plunger 50 normally separated. from the reaction plunger 32 by a spring 78 yieldable in response to a predetermined pressure in the master cylinder to allow them to abut. The head 54 of valve plunger 50 contains a valve element 80 comprising a pair of annular sealing ridges 82, 84 (Fig. 2) forming the exhaust and inlet valves respectively of chamber 28. As plunger 38 is moved to the right (Fig. 1) its end 88 engages ridge 82 to seal off chamber 28 from the atmospheric chamber 29 by way of passage 89 surrounding plunger 38, bore 64 and passage 66. Continued movement moves valve plunger 50 to open the inlet valve, i.e. raise ridge 84 from its seat 86 (Fig. 4), to pressurize chamber 28 from connection 60 through passages 58 and 89, the compressed air metering past shoulder 92 on plunger 38, the piston 24 being moved against spring 46, and the sleeve 30 and plunger 32 displacing fluid in master cylinder 12 to take up slack and lightly apply the brakes. When movement of plunger 38 ceases the inlet valve seat 86, carried by element 24, closes inlet valve 84 and the valve plunger will be in a lap position. On further movement of plunger 38, the inlet valve 84 opens to further pressurize chamber 28, pressure in master cylinder 12 is increased, as is the reaction force on plunger 32 which finally overcomes spring 70 to move plunger 32 to the left to contact valve plunger 50, so transferring the reaction to the manual plunger 38 and the foot pedal. Should the air pressure fail then as the plunger 38 is moved a collar 44 on the plunger engages the valve seat 86 to move the element 24 manually to apply the brakes.

Title: Improvements in or relating to boiler cleaners or soot blowers
IPC: F28G3/16
Filed: 1937-08-27
Abstract: 504,917. Soot blowers. BABCOCK & WILCOX, Ltd., GLINN, R. J., and HANDOLL, P. G. Aug. 27, 1937, No. 23544. [Class 99 (ii)] A control valve for a soot-blower is particularly applicable to boiler cleaning systems comprising a number of fluid-operated sootblowers adapted to be started in sequence wherein connection of the fluid supply to each succeeding blower is controlled by means operated in dependence on actuation of the preceding. blower. Actuation of control means for fluid which operates the valve is initiated by a member driven by the blower engine, actuation being completed independently of the member. The valve comprises a casing having a fluid inlet 2, an outlet 3 to the blower engine, and an outlet 4 to the corresponding valve of another blower. The valve member has differential pistons 8, 10 controlling the ports 3, 4, and a part 15 which is held on the seat 11 in the normal position shown. The spring and fluid-pressure loading is such that when the valve is lifted slightly off the seat 11 by a pawl 20, the valve is moved to open port 4 and close port 3. The pawl 20 is mounted on a rotary part of the blower between stops 21, 22, and is biassed by a light spring so that it is moved out of the return path of the valve stem after the valve has been raised. When it is desired that a blower shall rotate more than once before resting, the valve is moved only by the longer teeth 34.of a pinion 32, Fig. 3, actuated by a tooth 31. A spring- biassed plunger 36 acts on a cam 35 to move the tooth 34 from the return path of the valve spindle. Operation of the last blower of a series shuts off the fluid supply, each valve being reset by the spring 13 or by pressure fluid supplied and exhausted through ports 25, 26. If a blower fails the valve is actuated by fluid supplied through the port 24. For blowers of the kind comprising a blower tube which is advanced by fluid pressure to an operative position and then withdrawn, two control valves are provided, one of which is a reversing valve. Specification 437,801 is referred to.
