Abstract
The invention discloses a throttle valve body. The throttle valve body is connected with an air inlet branch pipe and comprises a valve body outer shell, a valve piece and a silencer inner core. The valve piece is installed at one end inside the valve body outer shell, the silencer inner core is embedded at the other end inside the valve body outer shell, a plurality of penetrating holes are formed in the wall of the silencer inner core, and air flow sequentially passes through the valve piece and the silencer inner core and enters the air inlet branch pipe. Due to the fact that the structure that the penetrating holes are formed in the wall of the silencer inner core is adopted, when the air flow conducts entering and penetrating through the valve piece, noise of the air flow passes through the penetrating holes. Due to the fact that acoustic impedance is changed, partial sound waves are reflected back, the other part of acoustic energy enters a cavity between the silencer inner core and the valve body outer shell, the Helmholtz resonance principle is utilized for enabling the acoustic energy to achieve the largest consumption, the throttle valve body plays resonance and attenuation roles in the noise of the air flow flowing into the throttle valve body, and therefore the noise of air flow radiation is reduced. Air inlet efficiency of the throttle valve body is basically not affected, and the forecabin arrangement and engine performance of a whole vehicle are not affected.
