Abstract

Carburateur comportant un dispositif de départ à volet excentré commandé par un premier organe thermostatique et une came de ralenti accéléré 8 qui entrouvre le papillon 6 quand le volet de départ 3 est fermé. Une capsule pneumatique ouvre partiellement le volet lorsque la pression dans le conduit d'admission diminue. Le déplacement des moyens pneumatiques est limité par des gradins supplémentaires prévus sur la came de ralenti accéléré. La capsule est associée à deux ressorts de rappel dont le premier, 35, agit en permanence et le second, 40, n'intervient que lorsque la course de la capsule dépasse une amplitude éterminée. Application aux moteurs à combustion interne.Carburetor comprising an eccentric flap starting device controlled by a first thermostatic member and an accelerated idle cam 8 which opens the throttle 6 a little when the starting flap 3 is closed. A pneumatic capsule partially opens the shutter when the pressure in the intake duct decreases. The movement of the pneumatic means is limited by additional steps provided on the accelerated idle cam. The capsule is associated with two return springs of which the first, 35, acts permanently and the second, 40, intervenes only when the course of the capsule exceeds a set amplitude. Application to internal combustion engines.
