Description

Technical Field

[0001] The utility model relates to the technical field of valve body assemblies, in particular to a compact throttle valve. Background Art

[0002] The motorcycle throttle valve is a device used to control the amount of air intake in the engine. It is usually located in the intake pipe of the engine. Its main function is to adjust the air flow entering the engine to meet the needs of different working conditions, thereby controlling the engine's output power and fuel economy. The motorcycle throttle valve consists of an adjustable valve. The opening of the valve is changed by rotating or moving the valve stem to adjust the air flow. When the motorcycle needs greater power output, the driver can increase the intake volume by adjusting the throttle valve, so that the engine can obtain more oxygen supply and increase power output; when the motorcycle needs to save fuel, the driver can reduce the opening of the throttle valve, limit the intake volume, and reduce the engine's load and power output.

[0003] The publication number is: CN102322357A. A motorcycle throttle assembly is disclosed, which solves the problems of large size, poor heat dissipation, short service life and poor detection accuracy of the existing motorcycle throttle assembly. The motorcycle throttle assembly includes a throttle body, a sensor, a bronchial pipe and an idle electronic valve. The sensor and the idle electronic valve are both fixedly connected to the throttle body. A rubber tube is connected between the throttle body and the intake manifold. The sensor includes a shell, a cavity is provided in the shell and an intake pressure sensor is placed in the cavity. The other end surface of the shell has a first through hole communicating with the cavity. A circular groove is provided in the middle of the shell and a fixed turntable and a magnet installed in the fixed turntable are installed in the groove. A temperature probe is plugged into the shell and a thermistor is plugged into the temperature probe.
