Abstract: This invention is a portable pneumatically driven pressure intensifying positive displacement hydraulic power unit that can be transported in a bag or backpack and carried or worn by the user. The device can be powered by any suitable high pressure gas that is preferably contained in a small pressure vessel for portability. The device can be used to supply high pressure hydraulic fluid to tools with a wide range of uses in many fields including construction, industrial, breaching, and emergency service situations. This novel device does not require an electric or fuel powered hydraulic fluid pumping system, which allows it to be very portable and used in almost any environment (e.g., hazardous atmosphere or under water) without being tethered to an electric or fuel powered power source.

Abstract: An oil-gas separated pressure cylinder, which combines a hydraulic cylinder, a pneumatic cylinder and a pres-pressure cylinder, and keeps the applied compressed gas and the storage hydraulic fluid apart, maintaining the quality of the hydraulic fluid and saving the hydraulic fluid replacement cost. When the applied compressed gas enters the pre-pressure cylinder to move a pre-pressure cylinder piston in forcing the storage hydraulic fluid out of an oil storage space of the pre-pressure cylinder into an oil storage space in the hydraulic cylinder, a hydraulic cylinder piston of the hydraulic cylinder is then forced by the hydraulic fluid to move a hydraulic cylinder piston rod against the workpiece, and then a pneumatic cylinder piston rod of the pneumatic cylinder is forced into the oil storage space of the hydraulic cylinder to enhance the pressure at the hydraulic cylinder piston rod against the workpiece.

Abstract: A power device having a power reservoir in which a compressible fluid is maintained under pressure, an accumulator piston and a drive piston which are simultaneously movable to retracted or cocked positions by the introduction of a non-compressible power fluid into a cylinder in which the pistons are reciprocably movable, the power fluid acting on exposed areas of the drive piston to move it with the accumulator piston until it reaches its fully cocked position whereupon further movement of the accumulator piston exposes additional areas of the drive piston to the pressure of the power fluid whereby the compressible fluid, acting through the power fluid, imparts drive movement to the drive piston and multiple seal means on said accumulator piston, reservoir means in said accumulator piston to trap any power fluid which has by-passed one of said seals to thereby avoid intermixing of said compressible and non-compressible fluids.
