Abstract
A valve with elastic deformation and having a tubular core adapted to form an internal air passage from an external longitudinal end of the valve to an internal longitudinal end, the tubular core being at least partially surrounded by a sleeve of elastically deformable material and having a bulb shape widening in proximity to the internal longitudinal end of the valve and ending in an internal longitudinal bulb end. A cup made of rigid material includes a first portion facing an internal longitudinal bulb end face and at least one second portion curved away from the internal longitudinal end of the valve, the cup serving as a way of limiting deformation of the bulb.
