16、onsisted of suction filter, gear pump, relief valve, hand operated directional valve, one-way throttle valve, hose assembly, quick-release couplings pressure meters and switches, oil pipes, oil tank air filters, etc.When the gear pump is rotated by a AC electric motor through a claw coupling, the pr

17、essure oil is brought into a relief valve where the no rmal pressure is in dicated by a pressure meter. A type M directi onal valve is used for cha nging the direct ions of actuators (hydraulic cyli nders) for their adva ncing and returni ng strokes. The on e-way throttle valve can cha nge the worki
