Problems solved by technology

[0004] According to the above requirements, people have produced an automatic choke door. Although the automatic choke door can automatically open and close the choke door, it cannot adjust its opening speed according to changes in internal and external temperatures. Realistically, because the choke valve is set near the carburetor, oil pollution and vehicle vibration are relatively large, and precision instruments cannot be used; during cold starting, if the choke valve is opened too quickly, because the fuel and air mixture is not rich enough to maintain the reaction degree, thus causing the gasoline engine to shut down

Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0025] see Figure 1-6 , a self-resetting choke shaft, including a door body 1, the interior of the door body 1 is movably connected with a rotating shaft 2, and the surface of the rotating shaft 2 is provided with a vent hole 15, the opening degree of the vent hole 15 can control the amount of air intake, and the rotating shaft 2 Both sides are movably connected with a spring 3, the end of the spring 3 away from the rotating shaft 2 is movably connected with ...

Abstract

The invention relates to the technical field of choke valves, and discloses a self-resetting choke valve shaft. The self-resetting choke valve shaft comprises a door body. A rotating shaft is movablyconnected to the interior of the door body. Springs are movably connected to two sides of the rotating shaft. A push-pull rod is movably connected to the end, far away from the rotating shaft, of eachspring. An air inlet mechanism is movably connected to the end, far away from the corresponding spring, of each push-pull rod. A resetting mechanism is movably connected to the surface of the rotating shaft. The air inlet mechanism comprises an air bellow. The air bellow is internally and movably connected with a ratchet wheel. The ratchet wheel is internally and movably connected with a gear. Amaterial continuously contracts and drives a threaded rod to move in the direction away from the rotating shaft, the threaded rod moves and drives the rotating shaft to rotate, and because the resetting mechanism is not symmetrically placed, the rotating shaft rotates towards one side while rotating, so that the springs pull the push-pull rods to move, the ratchet wheel connected with the push-pull rods is driven to rotate clockwise while the push-pull rods continuously move, and a fan impeller is slowly opened, so that the effect of adjusting the opening speed of a choke valve is achieved.

Description

technical field [0001] The invention relates to the technical field of choke valves, in particular to a self-resetting choke valve shaft. Background technique [0002] The choke valve is a part of the carburetor of a gasoline engine. It is generally located at the air inlet of the carburetor and operated through the control knob installed on the instrument panel. [0003] Its function is to properly close part of the intake port when the engine starts cold, increase the gasoline concentration of the mixture entering the cylinder, and improve the starting performance of the engine. Thickness will cause the engine to not run normally and cause excessive fuel consumption; when the engine is cold started, a part of the choke valve should be closed to help the carburetor work. [0004] According to the above requirements, people have produced an automatic choke door. Although the automatic choke door can automatically open and close the choke door, it cannot adjust its opening s...
