Carbureter throttle valve controller of engine

Abstract

Abstract PURPOSE: To keep the number of idling revolution constant even in the case when using either of a car heater or a car cooler, by holding a throttle valve of a carbureter in the first set opening larger than idle opening when employing the car heater, and by maintaining the throttel valve of the carbureter in the second set opening larger than the first set opening when making use of the car cooler. CONSTITUTION: A wax pellet 9 pulls up a holding rod 16 held to a diaphragm 7a only by the first set quantity n when a detecting the temperature of the open air not more than a set point, when using a car heater, and a valve spindle rod 15 of a throttle valve 3 of a carbureter is contact stopped in the closing direction of the throttle valve 3 of the carbureter by means of a holding nose 16a, thus maintaining the throttel valve 3 so that the throttle valve 3 of the carbureter not be closed not more than the first set opening Q 1 larger than idle opening Q 0 . When employing a car cooler, the second detector 13 detects the temperature of the open air not more than the set point, and the diaphragm 7a is held under a condition that deflects the diaphragm 7a only by second set quantity m larger than the first set quantity n.
