FIELD: machine building.
SUBSTANCE: invention relates to hydraulic coupling assembly (10) comprising fluid nozzle subunit (12) configured to be detachably connected to fluid receiver assembly (14). Subunit (12) of fluid nozzle comprises housing (16) nozzle assembly, forming pressurized and upstream channel (18) of fluid medium, having fluid medium outlet hole (20), and sleeve (22) installed with possibility of sliding on nozzle body (16) and made with possibility of sliding for opening of fluid outlet hole (20). Fluid receiver subassembly (14) comprises receiver body (26) forming downstream fluid channel (28), disc-shaped valve (30) with hydraulic drive, installed in body (26) of receiver, and dish-shaped valve (48) of receiver, which contains tray (54) of receiver and installed in housing (26) of receiver. At connection of nozzle subunit (12) with subunit (14) of receiver the following stages are performed: 1) housing (26) of receiver rests against sleeve (22), displacing it in axial direction relative to nozzle body (16), thereby releasing and thereby opening fluid outlet opening (20), providing passage of fluid medium through located upstream channel (18) of fluid medium; 2) a fluid passing through the upstream fluid passage (18), is supplied to downstream channel (28) of fluid medium, hydraulically actuating disc valve (30) with hydraulic drive, for its opening, wherein the fluid passes through the downstream fluid passage (28) when exiting receiver subunit (14).
EFFECT: invention provides connection of hydraulic coupling without excessive force with simultaneous prevention of fluid extrusion.
