Description

Technical Field

[0001] This utility model relates to the field of fuel dispenser technology, specifically a pneumatic fuel dispenser. Background Technology

[0002] The throttle cable controls speed. When the rider twists the throttle lever, the throttle cable pulls on related devices (such as controlling fuel supply), causing a change in power supply and thus altering the bicycle's speed.

[0003] Pneumatic fuel injectors require the user to pull the throttle cable to change the power supply and thus the vehicle speed. Pulling the throttle cable to change speed requires a certain amount of force, which varies depending on the vehicle speed, making it difficult and unsmooth to pull the throttle cable. Furthermore, existing fuel injectors often have poor internal sealing, making them prone to water and sediment ingress, which can further complicate the operation of the throttle cable.

[0024] Specifically, the throttle cable is connected to the connecting pipe 19 and wound around the connecting plate 16. The limiting bolt 20 on the outer shell 1 can be rotated according to the actual situation to limit the distance the connecting plate 16 can move within the outer shell 1. When adjusting the vehicle speed, the rotary handle 12 can be rotated, and the rotary handle 12 rotates the connecting rod 11 with the cooperation of the snap block 13 and the connecting bolt 14. The connecting rod 11 drives the connecting plate 16 to move within the outer shell 1 with the cooperation of the sealing ring 10, the polyoxymethylene spacer 15 and the outer shell 1, thereby using the connecting plate 16 to pull the throttle cable.

[0025] Understandably, the position of the limiting bolt 20 inside the housing 1 is used to limit the movement of the connecting plate 16 inside the housing 1;

[0026] In this embodiment, preferably, there are three mounting holes, and the mounting holes are arranged in a triangular pattern on the side of the outer shell 1 near the sealing groove;

[0027] Specifically, the waterproof cover 4 can be connected to the outer shell 1 with the sealing gasket 2 by fixing bolt 6, which facilitates the installation of the throttle cable and the connecting plate 16;
