Embodiment 1

[0031] see figure 1 with figure 2 , the present invention provides a throttle body for a small gasoline engine electric injection system through improvement, including a gear housing 1 and a transmission shaft 2, the gear housing 1 is installed in the middle of the left end face of the throttle body 3, and the right end face of the gear housing 1 The end is connected with the motor box 5, the transmission shaft 2 vertically runs through the middle part of the right end surface of the throttle body 3 and the rear end of the right end surface of the gear housing 1, the outer middle part of the transmission shaft 2 is fastened to the inner middle part of the throttle plate 4, and the right end surface of the throttle body 3 A position sensor 13 is installed, and a motor 8 is arranged at the right end of the inner bottom end surface of the motor box 5. The output shaft on the left side of the motor 8 passes through the front end of the right end surface of the gear housing 1 and ...

Embodiment 2

[0038] The present invention provides a throttle body for a small gasoline engine electric injection system through improvement. The front end of the right end face of the gear housing 1 is hollowed out, so that the output shaft on the left side of the motor 8 enters the gear housing 1 to connect with the driving gear 9 , the size of the outer side of the throttle plate 4 corresponds to the inner side of the throttle body 3, which is convenient for the throttle body 4 to completely seal the inside of the throttle body 3 after rotation.

[0039] The present invention provides a throttle body for a small gasoline engine electric injection system through improvement, and its working principle is as follows;

[0040] First, at first this device is fixedly installed on the designated position on the gasoline engine as a whole, and the two ends of the throttle body 3 are respectively connected to the proper position of the designated parts on the gasoline engine, and the motor 8 and ...

Abstract

The invention discloses a throttle body for a small gasoline engine electromechanical injection system. The throttle body comprises a gear shell, a transmission shaft, a throttle valve body, a throttle valve sheet, a motor box, a position sensor, a sealing and positioning mechanism and a ventilation mechanism. According to the throttle body for the small gasoline engine electromechanical injectionsystem, a sealing and positioning mechanism is located in the inner side of the gear shell, a rotating rod rotates and drives a worm and a worm wheel to rotate, in a rotating process of the worm wheel, a round block matches with a through hole to drive a transmission plate and a rotating frame to rotate leftwards, the rotating frame drives a U-shaped plate and a round rod to rotate leftwards to be separated from the inner side of a groove in the right end of the inner side of a barb plate, and then a sealing plate can be pulled to drive a fixing plate and a sealing strip to move outwards to be separated from the left end of the gear shell, and then maintenance or dust removal can be conducted on parts on the inner side of the gear shell, and the beneficial effects that the throttle valvebody is disassembled more quickly, the maintenance or the dust removal is conducted on the internal parts, and the working efficiency is improved are achieved.

Description

technical field [0001] The invention relates to the related field of a throttle body, in particular to a throttle body used in a small gasoline engine electronic injection system. Background technique [0002] The throttle body is a valve that controls the intake of the engine. It is a circular steel sheet with a shaft in the middle, which is connected to the throttle cable and controlled by the throttle cable. The throttle body is a device on the engine intake system. The throttle body is generally divided into three parts: the actuator, the throttle plate and the throttle position sensor, which are generally packaged as one. [0003] When the throttle body is used in a gasoline engine, the throttle body is usually connected and fixed by bolts, and for the sake of firmness, usually a large number of bolts are used, which brings inconvenience to later disassembly and maintenance and internal dust cleaning, and saves energy. The interior of the valve body is relatively seale...
