Claims

[Claims for Utility Model Registration] 1. A carburetor that is equipped with a bench lily portion, a throttle valve, and a float chamber and does not have a chiyoke valve, wherein the chiyoke valve is inserted from the upstream side of the bench lily portion of the carburetor. a bypass air passage is provided on the downstream side of the throttle valve; a control valve device that operates in response to engine temperature is provided in the bypass air passage; and a control valve device that operates in response to engine temperature; A starting fuel passage is provided, an ON-OFF solenoid valve device is provided in the starting fuel passage, and an air bleed passage is provided branching off from the starting fuel passage, and the air bleed passage is connected to the atmosphere. a first, a second and a third opening, the second opening being provided with a valve device actuated by manifold negative pressure, and the third opening being provided with a second valve device actuated in response to the temperature of the engine. 1. A chokeless vaporizer characterized by being provided with a valve device. 2. The chokeless carburetor according to claim 1, wherein the control valve device provided in the bypass air passage is opened when the engine temperature is low and closed as the temperature rises. 3. The chokeless carburetor according to claim 1, wherein the ON-OFF solenoid valve device is opened when the engine temperature is below a predetermined temperature, and is closed when the temperature increases. 4. The chokeless carburetor according to claim 1, wherein the second valve device is closed when the engine temperature is below a predetermined temperature and opened when the temperature increases.
