Patent ID: 8087436

Claim:
A modular connector system for connecting a first fluid system to a second fluid system, comprising: a connector body having a generally hollow sleeve with a connector end and an actuator end, the connector end and the actuator end have threaded surfaces, and a piston slidably disposed within the sleeve so that the piston and the sleeve can move relative to one another, the piston having a first axial end and a second axial end; the piston includes an axial fluid passageway and a radial fluid passageway, the axial fluid passageway extending from the radial fluid passageway to the first axial end of the piston, and a fitting is fixed to the radial fluid passageway and projects from the piston beyond an exterior surface of the sleeve for connection to the first fluid system, and the piston is not sealed with the sleeve by a sealing member between the radial fluid passageway and the actuator end; the second axial end of the piston includes an internally threaded hollow portion located on a central axis of the piston that does not extend into the axial fluid passageway and the radial fluid passageway; a plurality of actuator units, each actuator unit including a portion that is threadably connectable to the internally threaded hollow portion; a plurality of connector units each of which includes a threaded connection mechanism that detachably connects the respective connector unit to the connector end of the sleeve; and the threaded surface at the connector end of the connector body hollow sleeve enables connection to the threaded connection mechanism of one of the connector units and the threaded surface at the actuator end of the connector body hollow sleeve enables connection to a respective one of the actuator units.
