Claims

[Claims for Utility Model Registration] (1) The two carburetor casings 101 are integrally molded and intersect with each of the two main intake passages 102 bored in the casings 101 and move forward and backward. Two sliding valves 103 form throttle valves of each carburetor, and in a sliding valve dual carburetor in which each sliding valve 103 is always controlled to open and close to the same opening degree, the two main valves are Intake passage 1
A sliding on-off valve 113 that conducts and cuts off the 02 is placed between the two sliding valves 103.
A sliding valve type double carburetor that is disposed in contact with and controls opening and closing of the sliding opening/closing valve 113 in relation to the operating state of the engine. (2) The sliding opening/closing valve 113 is controlled to open and close by a negative pressure device 115 operated by the engine's intake negative pressure (Claim 1)
Sliding valve type double carburetor as described in . (3) The sliding on-off valve 113 sends an electric signal 123 representing the rotational speed of the engine and an electric signal 124 representing the opening degree of the sliding valve 103 to the control circuit 122.
Control motor 1 that operates based on the output signal input and calculated by
21. The sliding valve type dual carburetor according to claim (1) of the utility model registration.
