摘要:
A fluid coupling device has a male section (20) and a female section (21). Each of the sections has two rotatable ball-valve elements (30,31). A docking member (23,24) is mounted on each section to accommodate a misalignment of the flow passageways when the sections are brought together. When the sections are joined together, the ball valves automatically rotate sequentially from flow-preventing positions to flow-permitting positions.

A fluid coupling (30) has a male half (32) and a female half (31). Each half has a poppet (35,42) arranged to move toward and way from a seat (34,43). The male half (32) has an outer sleeve (38) which is adapted to guide initial joinder of the female half distal end (46). After the two halves have been initially joined, the male half body (39) is extended relative to the sleeve (38) so as to move both poppets (35,42) off their respective seats and to permit flow through the coupling. The coupling has protrusions (76) provided with sharpened edges which are positioned to scrape ice adhering to facing surfaces when the coupling halves are joined and separated.

A device (20) has an electrically-operated brake (37) and a manually-operated auxiliary brake (27). The electrically-operated brake includes a coil (70), a core (68), an armature (69), and an alternating series of friction pads (74) and brake disks (75), that are arranged to be compressed between the housing and the armature. The shaft brake (27) includes a collar (22) mounted on en the housing for combined axial and rotative movement relative thereto, a first interlock portion (106,110) mounted on the shaft (24), an annular member (84) surrounding the shaft and having a second interlock portion (85) and a spring (124) urging the member to move toward the shaft. The collar (22) is adapted to be selectively moved relative to the housing between a first portion at which the first (106,110) and second (85) interlock portions are physically engaged with one another, and a second position at which the first (106,110) and second (85) interlock portions are physically separated from one another. The shaft (24) may include a first and second shaft portions (25, 26), and a cam mechanism (125,126) that automatically releases the braking mechanism when the shaft portions (25,26) are rotated relative to one another, and that automatically re-engages the braking mechanism when the two shaft portions (25,26) are moved back to their initial null position.
