ABSTRACT OF THE DISCLOSURE An automatic coupling device to connect a tractor hydrau- lic system and a tractor-drawn device hydraulic system com- prising a panel secured on the tractor-drawn device and a body mounted on the tractor. The panel accommodates receiving unions with shut-off valves. The body has blind bores accom- modating hollow plungers each fitted with a shut-off valve at the end face operatively engaging the union. In each of the bores, the corresponding plunger defines a bottom chamber, the bottom chambers being intercommunicated. The hollow of one of the plungers communicates via an aperture in the side wall thereof with a pressure port, and the hollow of the other plunger, via a similar aperture in the side wall, with a drain port. In the device the pressure port and the drain port are provided in the body, the pressure port has a branch to the bottom chambers, and the aperture in the side wall of each of the plungers is disposed at the end face opposite to that operatively engaging the union. Such a structure of the device simplifies its construction and upgrades its dependability.
