<p>The subject of the patent being applied for is an accessory for tyre inflation pumps (both manual and with compressor). The fitting, the distributor body 2 of which is connected to the end of the pump piping, makes it possible to switch from one valve fitting (for example of the small "Regina" type) to another (for example of the large "Shrader" type) by means of the fast displacement of the pin 1. Pneumatic tightness is guaranteed by O-rings 3. Connection of the large valve type is guaranteed by screwing the ring 4 on the same valve and from the thrust of the pin 6 on the valve "needle". The solution proposed is applicable both as a standard fitting and as an accessory for later fitting. The sectors of use are those of the bicycle, motorbike, motorcar and all vehicles fitted with inflatable tyres. <IMAGE></p> |
