Abstract

PURPOSE: To improve quickness of response in disengaging the holding arm from the slide valve at the time of acceleration by interlocking the holding arm which controls opening of the slide valve of a constant negative pressure type carburetor with the actuating layer of throttle valve.
CONSTITUTION: A negative pressure operating slide valve 11 moves automatically up and down by means of Venturi negative pressure determined by the degree of opening of a fuel mixture throttle valve 1, and maintains the Venturi negative pressure at a constant. The throttle valve 1 is connect through a rod 5 to an actuating lever 4 and is opened or closed by means of an accelerator pedal which is not shown in the sketch. A holding arm operating link work consisting of a holding arm operating lever 15, rod 16, lever 14 and a slide valve holding arm 12 operates in link motion with this actuating lever 4. The arm 12 is in contact with the head of the slide valve 11. This contact is maintained until the slide valve 11 is half open. At the time of acceleration, the arm 12 is suddenly lifted up so that the slide valve 11 further opens by means of the Venturi negative pressure only.
