Abstract

The invention discloses a carburetor provided with a rotary valve and capable of being started rapidly. The carburetor comprises a carburetor body, a fixing frame and a starting device, the fixing frame is detachably arranged on the carburetor body, and the starting device comprises the rotary valve capable of rotating around the longitudinal axis so as to open or close a mixing channel. A cylindrical cavity is formed in the rotary valve, a ventilating hole is further formed in the outer wall, perpendicular to the cylindrical cavity, on the rotary valve, and an oil needle concentric with the rotary valve is arranged in the rotary valve. A rocker arm capable of driving the rotary valve to rise is connected to the upper portion of the rotary valve, the rotary valve and the rocker arm are connected through a through hole penetrating through the middle of the fixing frame, and a reset spring is arranged between the rotary valve and the fixing frame. According to the carburetor, the rockerarm can drive the rotary valve to rise, the size of a fuel spray nozzle of a main jet is changed by moving the oil needle, the air inlet quantity is also increased through the ventilating hole while the oil inlet quantity is increased, the process is simple, and using is convenient.

Description

technical field [0001] The invention relates to a carburetor, in particular to a quick start rotary valve carburetor. Background technique [0002] The carburetor is a mechanical device that mixes a certain proportion of gasoline with air under the vacuum generated by the engine. Generally, a rotary valve carburetor has a fuel and air mixing channel, and a cylindrical cavity that is transverse to the mixing channel moves axially inside the carburetor body, and the flow rate of the mixed gas passing through the cavity can be adjusted by the rotation of the rotary valve , the cylindrical cavity is also installed with an oil needle fixed on the rotary valve concentric with the rotary valve. The oil needle extends into the main fuel nozzle installed on the main body concentric with the rotary valve. The through hole of the cavity, thus allowing the fuel to flow from the metering chamber communicating with the main nozzle into the mixing channel. The axial movement of the rotar...
