気化器
Document Type and Number:
Japanese Patent JP5539702
Kind Code:
B2
Abstract:
A carburetor having a choke valve has an open-close valve sliding reciprocatingly inside a valve hole partway along a bypass air passage. The open-close valve, pressed by urging member, slides according to a rotation angle of a choke valve shaft while a distal end side continuously contacts a side face of the shaft. A projecting part, urged by a coil spring, projects from a distal end of a body. The urging member includes a temperature-sensitive material that expands at or above a prescribed temperature. When the choke valve is closed and the ambient temperature is less than the prescribed temperature, the bypass air passage enters a closed state while the body remains in a closed-valve position; and when the ambient temperature is at or above the prescribed temperature, the urging member elongates and the body enters an open-valve position, and the bypass air passage enters an open state.
