Abstract

PURPOSE:To make an additional fuel supplying mechanism unnecessary and uniform the atomization of the fuel and the mixture thereof by a method wherein the annular Venturi is formed between an axially reciprocating movable body and a throat section opening the orifice thereof at the inner peripheral surface of a housing. CONSTITUTION:The movable body 3, reciprocable into up-and-down directions along the axial direction of an air path and movable in accordance with the movement of an accelerating pedal, is arranged in the air path coaxially therewith while the throat section 2, protruded inwardly with a reduced diameter so as to form the annular Venturi between the upper outer surface of said movable body 3, is provided at the inner surface of a housing 1. The annular orifice 4, communicating with a supply path 23, is opened at the throat section 2 along the whole periphery of the minimum inner-diametral section and the fuel is supplied through a float chamber and the supply path 23 by a vacuum generated by an airflow being flowed through the Venturi formed by the throat section 2 and the movable body 3.
