Abstract
A pressure booster having arranged therein drive cylinders on both sides of a boosting cylinder is provided with a pair of pilot valves that are actuated when pistons of the drive cylinders abut against the moving ends thereof. A pair of actuation valves switch the supply state of a pressure fluid to pressure chambers of the drive cylinders. When the pilot valves are actuated, the pressure fluid passes through the pilot valves and is supplied to the pair of actuation valves, and the supply state of the pressure fluid is switched.
Claims14
A pressure booster including a booster cylinder and drive cylinders disposed respectively on both sides of the booster cylinder, comprising:
- a pair of pilot valves, each pilot valve configured to be actuated when a piston of the corresponding drive cylinder is in abutment with the pilot valve at a moving end of the piston;
- and
- a pair of operating valves, each operating valve configured to switch a state of supply of pressurized fluid from a pressurized fluid supply source between pressure chambers of the drive cylinders, wherein:
- when each of the pilot valves is actuated, the pressurized fluid from the pressurized fluid supply source is supplied through the corresponding pilot valve, and from the corresponding pilot valve to the pair of operating valves, to thereby switch the state of supply of the pressurized fluid in the drive cylinders.
