Abstract
The cryogenic fluid generator includes at least one pump assembly having an actuator mounted to a container assembly. A pump assembly housing includes a longitudinal positioning opening and a pressurization cavity at a distal end terminating with a pump assembly outlet. An internal check valve assembly includes a shaft positioned within an opening of the pump assembly housing that extends into the pressurization cavity. The shaft is attached to the actuator and includes a longitudinal guidance slot; a fluid passageway; and, an internal sealing surface. A positioning bar assembly is positioned within the guidance slot. A connecting rod is securely connected at a first end to the positioning bar assembly, the connecting rod being positioned within the fluid passageway and terminating with a flow inhibiting element. A seal is positioned between the pump assembly housing and the check valve to provide a closure for the pressurization cavity.
