Abstract
Applicant provides a novel liquified booster pump. The pump takes high pressure boosted gas to a higher pressure. The pump is a pneumatically driven liquified gas booster pump with a shuttle valve enclosed within a body of the pump. Furthermore, the gas which is use to be boosted is carried from an inlet on the body of the pump to an outlet on the body of the pump, the boosted gas being carried entirely within the body of the pump with no external tubing. The pneumatically driven booster pump has a double ended piston within the central body and at least one shuttle valve incorporated in the piston for transferring gas from one side of the piston to the other.
