Abstract:
A closure head for a fuel tank filler pipe allowing automatic opening of a shutter under action of thrust of a nozzle on a device integrated into the top of the filler pipe and closing of the shutter when the nozzle is withdrawn. The locking of the shutter is achieved by a mechanism connected to a bodywork flap such that locking and squashing of a seal are achieved upon the closing of the bodywork flap and the opening of the bodywork flap cannot unlock the shutter without the nozzle additionally being introduced into the system. A method for opening a filler head employs the device.
Abstract:
The present invention provides an accessory for a flap for use with an inner tube and wheel, comprising a base of oblong shape whose upper face is provided with a rigid insert in the form of a hollow cylinder, said accessory being made by molding a single material that resists creep up to a temperature of 180° C., to prevent the flap creeping through an orifice in the wheel.
Abstract:
In order to be able easily to inflate a tire mounted on a rim with a seal ring (6) arranged between the two beads, without presenting the ordinary inconveniences in mounting, the inflation device is formed of a valve (V, V') provided with a locking element (2, 2') intended to be associated with a locking member (83, 51) separate from the valve. The method of inflation consists then in introducing the valve (V, V') provided with its stem (1, 1') and its locking element (2, 2') into the orifice (64) provided in the ring 6 and into the locking member (83, 51), and then turning the valve.

Abstract:
An annular element (3) placed between the two beads (12) of a tire (P) moed on a flat-base rim (J). In order to be able to use the tire on said rim without an inner tube, the annular element, in order to assure the tightness of the assembly, has in meridian section a contour and, in particular, two lateral sides (30) such that the clamping s between the ring and the beads, which is zero or even negative at the base of the ring, increases then slightly over a certain radial distance h.sub.1 and then more greatly over a distance h.sub.2 radially adjacent the first distance.
