Connection system for quick safety coupling for hydraulic braking circuits of trailers

摘要

A connection system for a quick safety coupling for hydraulic braking circuits of trailers is constituted by a port for connection to the hydraulic circuits and by a valve body (2) being mounted so as to be rigidly coupled to the body of a conventional unit for distributing pressurized fluid to the braking circuit of trailers, which is mounted on a tractor and is internally provided with ducts for connection to the distribution unit (3) and with a rear opening for the coupling of the port, and with a retention element (6) which can move transversely to the slider (3a), in a suitably provided seat formed in the valve body (2), in contrast with elastic return means and is actuated by way of corresponding means which are rigidly coupled to the port between a position for interfering with the slider (3) and locking its axial sliding and a position in which there is no interference and sliding is freely allowed. <IMAGE>
