Abstract
The hydraulic drive for the cyclic operation of machinery at frequencies up to 500 Hz consists of a body (1) with a central double ended piston (2) working in cylinders (9, 9a). Each cylinder is connected to a double beat slide valve (3, 4). The slide valves are continuously oscillated by rotating cams (5, 6) and compression springs. The operation of the slide valves is so phased that when the piston (10) is exposed to one of the pressure sources, which is up to 10,000 psi the piston is exposed to low pressure so that the double piston oscillates simultaneously with the slide valves.
