Abstract
PURPOSE:To decelerate or accelerate a piston speed in a fluid hydraulic cylinder to a different arbitrary speed by providing two variable throttle valves, two-port valve and a check valve to be combined. CONSTITUTION:A speed control valve D arranges in series two variable throttle valves R1 and R2 between in-out flow ports A and B of fluid, parallelly providing a normally open or normally close two-port valve E with one variable throttle valve R2 further directly connecting one check valve C to in-out flow ports A, B of the fluid not via the variable throttle valves R1, R2. By the arrangement thus obtained, decelerating or accelerating the speed of a fluid hydraulic cylinder to an arbitrary value, two-stage speed control can be performed. When the two variable throttle valves R1, R2 are arranged in parallel, the two-port valve E may be provided in series to one of the variable throttle valves.
