Abstract

Ce distributeur est du type de celui décrit dans le brevet principal 75 20856, dans lequel la conduite de communication 47 entre la chambre de l'obturateur principal et celle de l'obturateur pilote est constituée par un alésage axial traversant l'obturateur principal. Dans le distributeur selon l'invention, dans l'alésage axial précité 46 est disposé un tube 61 déplaçable relativement à l'obturateur principal 21, qui présente à une de ses extrémités un siège 59 pour l'obturateur pilote 23 et le tube prend en direction de l'obturateur pilote 23 une position définie, alors que dans le sens inverse il est maintenu avec une certaine élasticité (ressort 68). De ce fait, une course de l'obturateur pilote éventuellement supérieure à sa course utile n'a pas d'effet gênant sur le fonctionnement et la conduite de communication est fermée dès que la chambre de pilotage commence à se décharger.This distributor is of the type of that described in main patent 75 20856, in which the communication line 47 between the chamber of the main shutter and that of the pilot shutter is formed by an axial bore passing through the main shutter. In the distributor according to the invention, in the aforementioned axial bore 46 is disposed a tube 61 movable relative to the main shutter 21, which has at one of its ends a seat 59 for the pilot shutter 23 and the tube takes in direction of the pilot shutter 23 a defined position, while in the opposite direction it is maintained with a certain elasticity (spring 68). As a result, a travel of the pilot shutter possibly greater than its useful travel has no annoying effect on the operation and the communication line is closed as soon as the control chamber begins to discharge.
