Filling tap for pressurized gas bottle comprises body having valve controlled by handle for releasing gas passage and gas outlet drilling downstream of valve, chamber in outlet drilling forming valve seat

摘要

The filling tap comprises a body (1) having a valve (5) controlled by a handle (9) for releasing or closing the gas passage (3). It has a gas outlet drilling (13) emerging downstream of the valve. The tap comprises a chamber (14) formed by the widening (19) of the outlet drilling. The chamber upstream end forms a valve seat (15) and a stop (18) integrated in its wall is retractable under a force greater than a threshold value. A hollow cylindrical valve (30) closed by a bottom at its upstream end is edged by a valve seat surface and housed in the chamber. A guide boss is continued upstream and downstream by a ramp. Independent claims are included for a tap tool and equipment for the filling of a gas bottle.
