  • Means For Warming Up And Starting Carburetors (AREA)

Abstract

PURPOSE: To purify exhaust in such a way of making choke valve opening as fast as possible after starting by setting the choke valve opening at the first stage of warming up by thermowax.
CONSTITUTION: Moving amount of a diaphragm 34 and a salient rod 32 which are displaced by air intake negative pressure at the time of perfect explosion of the engine is regulated by the position of thermowax 50. On the other hand, a bimetal 16 responds to engine temperature and opens a choke valve. When the engine has started up resulting in being brought to make perfect combustion, the diaphragm 34 moves until the thermowax 50 is brought into contact at its end in such a way that air intake negative pressure works through a throttle 36a upon a diaphragm device 24, to gradually open the choke valve.
