| 摘要 |
Device (10) for simultaneous assisted coupling and uncoupling of one or more quick couplings (8, 9) comprising one group of parts with a mobile plate (80) to support one or more female half couplings (20) connected to the user appliance, a second group of parts with a fixed plate (90) to support one or more male half couplings (60) connected by one or more connectors (92) to the power delivery of a servo-control (81) that reduces residual pressure to zero in the delivery chambers (91) of the male half couplings (60) in the stages of coupling and uncoupling with the female half couplings (20), discharging said residual pressure into a discharge port (99) through ducts (118, 119, 120) served by a check valve (121) and by a cut-off valve (110) opened by the servo-control (81) during the coupling and uncoupling stages. |
