Abstract

The invention discloses a rotary valve carburetor capable of quick start, which 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 includes a Axis rotation to open or close the rotary valve of the mixing channel, the rotary valve is provided with a cylindrical cavity, and a ventilation hole is also provided on the outer wall of the rotary valve perpendicular to the cylindrical cavity, and the rotary valve is provided with a The oil needle of the rotary valve is concentric. The upper part of the rotary valve is connected with a rocker arm that can drive it to lift. The rotary valve is connected with the rocker arm through the through hole in the middle of the fixed frame. A return spring is arranged between the rotary valve and the fixed frame. The invention can drive the rotary valve to lift by the rocker arm, move the oil needle to change the size of the fuel nozzle of the main nozzle, increase the fuel intake, and increase the intake volume through the vent hole. The process is simple and easy to use.

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...
