ABSTRACT:
A manually operated, power-assisted, self-sealing fluid coupling which utilizes pressurized fluid to interconnect the coupling parts. A sleeve within one part selectively locks to the other part and utilizes an expansible chamber motor to draw the other part into the one coupling part, and a second expansible chamber motor associated with the sleeve neutralizes the coupling force of the first motor during disconnection and manual operation of the sleeve through a valve component disconnects the coupling parts.
