Abstract
A high pressure coupling includes a tubular piston having a longitudinal axis and first and second opposite ends, with the tubular piston being moveable between a disengaged position and a pressurized position. A coupling mechanism surrounds the first end of the tubular piston, with the coupling mechanism including an un-coupled configuration and a coupled configuration. A sleeve is engaged with the coupling mechanism for controlling operation of the coupling mechanism. The sleeve is moveable between a first position at which the coupling mechanism is in the un-coupled configuration and a second position at which the coupling mechanism is in the coupled configuration. A detent mechanism is provided which is actuatable by the tubular piston. The detent mechanism is engageable with the sleeve at the disengaged position of the tubular piston to hold the sleeve at the first position and the detent mechanism is engageable with the sleeve at the pressurized position of the tubular piston to hold the sleeve at the second position.
