The speed regulator is basically a closed hydraulic circuit without its own power source. It consists of a cylinder filled with oil, a piston rod and piston, a control valve and a compensation tank. When the regulator rod couples with an external moving organ, the piston rod moves to close the one-way valve inside, which forces the oil through the transfer pipe towards the control valve, where it encounters a restriction that can be adjusted externally to determine the speed. The oil flows through the control valve into the other chamber which is separated by the piston. During return movement, the one-way valve opens and the oil flows freely to enable a rapid return movement. The in-line or in-parallel tank compensates the rod movement and minimum blow-by. The dip-stick in the tank can be used to determine the oil level. These speed regulators can be fitted with control valves as follows acceleration valves (SKIP), stop valves (STOP), acceleration + stop valve combinations (SKIP + STOP). These valves are normally opened and controlled by air. Modified in this way, speed regulators can stop and/or accelerate the speed set by an externally adjustable hand-wheel.
