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.
Claims14
A pneumatically driven booster pump comprising:
- a double ended piston having a central body, the central body having a pair of drive faces, the double ended piston having a pair of removed ends, each of the removed ends with a driven face thereon;
- at least one shuttle valve for transferring a drive gas from one of the pair of drive faces to the other of the pair of drive faces;
- and
- a body housing including a piston chamber for enclosing the double ended piston, walls defining a chamber for enclosing within the body housing the shuttle valve, an inlet port for receiving a fluid to be boosted and an outlet port for providing the boosted fluid at a pressure greater than the pressure that it was received at the inlet port;
- wherein the piston is adapted to slidably receive the shuttle valve through the central body of the piston.
