Abstract
A sliding throttle valve type carburetor comprising a sliding throttle valve, an air intake passage and a fuel float chamber, the sliding throttle valve extending along a line of intersection with the intake passage and being disposed at an acute angle relative to the portion of the intake passage upstream from the sliding throttle valve. The sliding throttle valve forms an angle of intersection with the portion of the fuel surface in the float chamber upstream from the sliding throttle valve which is greater than the aforementioned acute angle.
Claims23
A sliding throttle valve type carburetor comprising a sliding throttle valve, an air intake passage and a fuel float chamber, said sliding throttle valve extending along a line of intersection with said intake passage and being disposed at an acute angle relative to the portion of said intake passage upstream from said sliding throttle valve, said sliding throttle valve forming an angle of intersection with the portion of the fuel surface in said float chamber upstream from said sliding throttle valve which is greater than said acute angle.
A sliding throttle valve type carburetor comprising a body defining an air intake passage, a fuel float chamber on said body, means for supplying fuel into said float chamber to a given level to establish a fuel surface, and sliding throttle valve means slidably mounted in said body to extend across said air passage and being movable along a line of operation for controlling air flow through said passage and delivery of fuel thereto, said body including main fuel passage means extending rectilinearly from the float chamber to said air passage for delivering fuel to the air in said passage, said sliding throttle valve means including a fuel metering needle valve slidably received in said main fuel passage means in linear alignment therewith, said line of operation of said sliding throttle valve means forming an acute angle with the portion of the intake passage upstream of the sliding throttle valve means, and forming a greater angle with the portion of the fuel surface in the float chamber upstream of the intersection of said line of operation with said fuel surface.
