Abstract

A sealing gasket (100) formed as a single piece of resilient material and comprising: a first toric part (10) having a first torus diameter; a second toric part (20) having a second torus diameter greater than the first torus diameter; and at least two arms (31, 32), comprising a first end and a second end, each first end being linked to the first toric part and each second end being linked to the second toric part; characterized in that, in a folded state, said sealing gasket is substantially planar, and in that, for each arm, said first end is a first bend (311, 321) oriented in a first direction and said second end is a second bend (312, 322) oriented in a second direction, opposed to said first direction, in such a way that each arm extends substantially circumferentially between its first bend and its second bend, the first bends of the different arms being further all oriented in the same first direction, and accordingly the second bends of the different arms being all oriented in the same second direction, so that the gasket can be deployed by a helical unwinding in a three dimensional unfolded state.

Abstract

The aim of the invention is to propose a joint for a quick connector that can be produced economically, and provides a seal in a wide range of fluid pressures while having reduced fitting forces. - More specifically, the present invention concerns an annular seal (10) made from an elastically deformable material, having an axis of revolution (AR) and a transverse axis (AT): and being generally T-shaped in the longitudinal axial section, having in the rest position: ~ a peripheral strut extending parallel to the axis of revolution (AR) and having an inner face, turned towards the axis of revolution (AR), an opposing peripheral outer face, and two lateral faces linking the inner and outer faces, ~ a bar substantially perpendicular to the strut extending parallel to the transverse axis (AT), from the inner face of the strut to the axis of revolution (AR), in which the outer face of the strut is concave.

• F16L 21/03 - Joints with sleeve or socket with elastic sealing rings between pipe and sleeve or between pipe and socket, e.g. with rolling or other prefabricated profiled rings placed in the socket before connection
• F16L 37/02 - Couplings of the quick-acting type in which the connection is maintained only by friction of the parts being joined
