Abstract

Improvements in carburettors, for internal combustion engines, of the type comprising an acceleration pump whose variable volume chamber is connected, on the one hand, to a constant-level tank by means of a suction channel provided with a suction valve and, on the other hand, to the part of the carburettor intake duct located upstream of its main throttle member by means of a discharge channel provided with a discharge valve and a calibrated injection port, which pump comprises a mobile pumping member, which partially limits said chamber and is coupled to the main throttle member to carry out an impulse stroke when opening movements of said main throttle member take place, characterized by the provision of a deformable member (23) due to temperature variations, arranged in the variable volume chamber (9) so that is immersed in the fuel contained in this chamber, an organ (23) that decreases the amplitude of said stroke when the fuel temperature increases.
