ABSTRACT:
A tolerance compensated quick coupling comprises a projecting or bulging portion of a male coupling, which can be axially driven in a valve body, the coupling projecting or bulging portion ending with a flange inside the valve body, said flange in said valve body being followed by an axially movable annular body which, through a spring bearing on the bottom of the valve body, is pressed against the flange, the movable annular body having, on a side thereof facing the flange, a circumferential slot housing a sealing ring element contacting an inner surface of the flange, the movable annular body being moreover provided, on an outer circumferential side thereof, with a slot in which is engaged a circumferential sealing ring contacting an inner wall of the valve body.
