構成したことを特徴とする油圧ジヤツキ。 In a single-acting hydraulic jack in which the piston is actuated via a hydraulic valve by the operation of an air-driven pressure booster pump driven by compressed air, an upper limit stop bushing with the same diameter as the piston ring of the hydraulic jack is connected to the piston ring. After installation, drill a pair of piping holes at substantially opposite positions at the base end of the cylinder, connect one piping hole to the compressed air source, and connect the other piping hole to the air-driven pressure booster pump and piping. A hydraulic jack characterized in that it is configured so that pressure oil is supplied to a piston head side from a hydraulic valve that is connected to the hydraulic valve and functions by the operation of the pressure booster pump.
