Abstract
PURPOSE: To improve the responsiveness of a variable venturi type carburetor by constituting same such that a cylinder chamber formed above a piston of the carburetor is acted upon by fuel pressure by way of a pressure responsive member.
CONSTITUTION: A piston 5 is didposed perpendicularly to a suction passage 3 for sliding movement in the vertical direction in an outer cylinder 9. The piston 5 has therein a cylinder chamber 10 whichis defined by a cylindrical rod 17 fixed to the piston 5 and a guide 9a fixed to the outer cylinder 9. Negative pressure in the upstream of a throttle valve 1 is introduced into a chamber 41 defined by a diaphragm 39 of a pressure responsive member 37. A plunger 45 fixed to the diaphragm 39 has a piolt valve 47 formed thereon. Movement of the valve 47 allows fuel to be introduced into the cylinder chamber 10 from a fuel tank 30 by way of a pump 29 and passages 48, 49. The position of the metalling rod 18 is corrected by the fuel pressure acting upon to this chamber 10 to regulate fuel from a jet 20a.
