Claims

[Scope of utility model registration request]

(1) A recess 5 communicating with the main ventilation passage 2 through the fuel passage 13 is formed on the outer side of the carburetor housing 1, and a fuel pressure control membrane 7 is provided between the periphery of the recess 5 and the lid 6 of the recess 5. The fuel pressure control membrane 7 and the recess 5 define a fuel chamber 5, and the fuel pressure control membrane 5 and the lid 6 define a fuel pressure control chamber 15. The fuel pressure control chamber 15 has a fuel inlet 9 that communicates with a discharge port of a fuel pump 16 formed integrally with or separately from the carburetor housing 1 via a throttle 17 . a fuel inlet 19 that is controlled and communicates with the outlet of the fuel pump 16;
It has a return fuel outlet 20 that communicates with the fuel supply side of the fuel pump 16 via a fuel throttle 18, and is disposed in the fuel pressure control chamber 15 and engages with the needle valve 8. A fuel pressure control lever 10 is disposed that is biased by a spring 12 in the direction of closing the fuel inlet 19, and the fuel pressure control lever 10 is activated by the deflection of the fuel pressure control membrane 7 as the fuel pressure in the fuel chamber 5 increases. A floatless carburetor characterized in that the needle valve 8 rotates in a direction to open the fuel inlet 19.

(2) Utility model registration claim No. 1, wherein the fuel pump 16 formed integrally with or separately from the carburetor housing 1 is a fuel pump that performs a pumping action using pulsating negative pressure generated in the engine. Floatless vaporizer as described in section.

(3) The floatless carburetor according to claim 1, wherein the fuel supply side of the fuel pump 16 is a fuel tank 22 connected to an inlet of the fuel pump 16.

(4) The floatless carburetor according to claim (1), wherein the fuel supply side of the fuel pump 16 is an inlet of the fuel pump 16.
