Abstract

A plug-in coupling for pressure application systems, including a receiving component, a connector component with a connecting shaft, an expanding cylinder supported on the connecting shaft between a radial step and a limit stop, and a spring unit initially supported on the expanding cylinder. The receiving component defines an opening and has a holding element, which is biased in a closed position and movable to an opened position. The connecting shaft of the connector component can be inserted into the opening of the receiving component along an insertion direction thereby engaging the radial step with the holding element to prevent loosening of the connector component from the receiving component. In this position, the expanding cylinder is located between the spring unit and the limit stop. The spring unit can be guided over the expanding cylinder in a direction opposite the insertion direction and the expanding cylinder can be moved along the insertion direction thereby disengaging the radial step from the holding element to allow release of the connector component from the receiving component.

Dependent claims

A plug-in coupling for pressure application systems, comprising:

a receiving component defining an opening and a recess, and having a holding element secured within said recess, said holding element biased in a closed position, and movable to an opened position;
a connector component having a connecting shaft, said connecting shaft having a radial step engageable with said holding element and a limit stop;
an expanding cylinder supported on said connecting shaft between said radial step and said limit stop, said expanding cylinder including a flange having a recess;
and
a spring unit initially supported on said expanding cylinder;
and wherein
said connecting shaft of said connector component is adapted to be inserted into said opening of said receiving component along an insertion direction thereby engaging said radial step with said holding element to prevent loosening of said connector component from said receiving component, and thereby securing said expanding cylinder between said spring unit and said limit stop;
said spring unit is adapted to be widened and guided over said flange in a direction opposite said insertion direction and said expanding cylinder is adapted to be subsequently moved along said insertion direction thereby disengaging said radial step from said holding element to allow release of said connector component from said receiving component.
