Abstract: Male fluid couplers (14) are attached to a control valve (94) mounted in a holder (96). Female fluid couplers (16) have their sleeve members (72) held in an aperture (108) in a sleeve member retainer (110) by snap rings (112). Lever arms (122 and 124) are attached to the sleeve member retainer (110) by pins (126 and 128). Pins (134 and 135) on the lever arms enter slots (136) in the male holder (96). Movement of the lever arms (122 and 124) moves the female couplers (16) into engagement with the male fluid couplers and allows locking balls (40) to move into locking ball grooves (38). Upon release of the handle (130), the spring (80) moves the sleeve member (72) in a position locking balls (40) in the grooves (38). Movement of the handle (130) in the opposite direction moves the sleeve members (72) into position to release the balls (40) from the grooves (38). Continued movement of the handle (130) moves the female couplers (16) from engagement with the male couplers (14).

Abstract: A novel quick disconnect ball joint coupling which utilizes as a misalignment ball locking mechanism, a combination of a plurality of locking balls and a locking sleeve. The locking sleeve provides an annular race or groove for receiving the locking balls, thereby obviating the high stress point-to-point contact problem associated with prior art locking ball techniques, but still provides the advantage of high speed, low torque rotation available with the use of such locking balls.

The locking sleeve is preferably spring loaded so that upon rotation, the locking sleeve remains stable with respect to the misalignment ball, thereby gaining the benefits of the low friction of a ball and race configuration during rotation.

Abstract: A quick disconnect coupling for connecting together two conduits in a high pressure fluid-carrying system. The coupling includes a female part (coupler) and a male part (nipple) each provided with a flow through channel, and each provided with a cut-off valve.
