Patent attributes
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.
