| 摘要 |
<p>The present invention relates to a multi-coupling device (1) of the plate type for simultaneously connecting a plurality of hydraulic, electrical and pneumatic lines by means of quick couplings. The device (1) according to the present invention is characterized in that it comprises, in the main body (1a) of the multi-coupling plate (2), a drainage line (10) which hydraulically connects the seats of all the female couplings (3), and in that it comprises at least one female coupling (3) provided with automatic means (10a, 33, 34) for draining the pressurized fluid, adapted to automatically deviate the fluid flow towards the drainage line (10) when the female couplings (3) are not connected to a male coupling (4), thus avoiding the dangerous accumulation of pressurized fluid in the female couplings (3).</p> |
