Abstract
194,611. Rayner, C. H. T., and Rayner, P. June 24, 1922. Fluid-actuated gears.-The cylinder is provided with separate admission and exhaust ports c, e, f, d at each end which are controlled by separate valves p, q having extensions r, s which abut and enter a chamber o open to the atmosphere, so that the fluid-pressure locks the valves in their operative positions. Each valve is thrown by fluidpressure passing to exhaust through the port e or f and is controlled thereby, and by the compression acting on the large end of the other valve. In a modification, the valves seat in end plugs, and supplementary fluid-pressure leakage ports are provided to facilitate the throw of the valve.
