Abstract (en)
The push-button includes a tube (3) welded into a calibre (4). A cylindrical element (6), comprising a head (7), a collar (8) and a stem (13) which are made in one piece which therefore cannot be dismantled, slides in the tube. At rest, the collar bears, through the restoring force of a spring (10), on an annulus (5) closing the outer portion (2) of the tube so that the packing (12) presented by the collar is not soiled by dirt from outside. The tube is blocked by a hollow stopper (16) furnished with a thread (18) screwed into a tapping (17) formed inside the portion (1) of the tube penetrating into the calibre. <IMAGE>
