Abstract
The present invention relates to a throttle valve for a vehicle, and more particularly, to a throttle valve for a vehicle, which comprises a throttle body having a passage for transferring sucked vehicle outside air to the engine side and having a step portion on its inner surface, And a valve plate that closes the flow path by contacting the step portion, thereby preventing wear and damage of the inner surface of the throttle body due to repeated operation of the valve plate, Thereby reducing the phenomenon of sticking to the surface of the substrate.
Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a throttle valve for a vehicle, and more particularly, to a throttle valve for a vehicle that adjusts a flow rate of a sucked vehicle outside air and feeds the throttle valve to an engine side.
Generally, a throttle valve for a vehicle is connected to an accelerator pedal of a driver's seat and opened / closed to adjust the suction amount of the vehicle's outside air. The outside air of the vehicle is generally introduced into the throttle valve after removing the impurities through the air cleaner. The vehicle outside air whose amount is controlled by the throttle valve is sent to the combustion chamber at the engine side and used for the combustion process.
The conventional throttle valve is connected to the accelerator pedal through a wire, and the opening and closing of the throttle valve is controlled depending on whether the pedal is mechanically depressed. In recent years, the throttle valve senses the state of the accelerator pedal, An electronically controlled throttle valve for controlling the opening and closing of the throttle valve is generally used.
In this regard, Korean Patent Laid-Open Publication No. 2002-0055746 (Patent Document 1) has been disclosed as a prior art related to a conventional vehicle throttle valve.
Patent Document 1 discloses a technique in which the distribution of intake air is improved so that the intake air supplied to each combustion chamber in the throttle body is uniformly distributed to the distribution pipes, thereby reducing the difference in the air-fuel ratio between the combustion chambers. However, the throttle valve disclosed in Patent Document 1 has the same problems as the conventional throttle valve to be described later with reference to Fig. 1 and Fig.
1 is a cross-sectional view showing a conventional throttle valve, and Fig. 2 is a partially enlarged view of a portion A in Fig.

However, since the conventional throttle valve as described above has to be tapered and sharpened at the
In addition, there is a problem that the risk of injury to the user increases when the throttle valve is assembled or installed by the
When foreign substances such as carbon accumulate on the
In order to solve the above problems, it is an object of the present invention to provide a vehicle throttle valve which reduces the possibility of wear and damage of the inner surface of the throttle body due to repeated operation of the valve plate, .
It is also an object of the present invention to provide a throttle valve for a vehicle that reduces the risk of injury to a user when assembling or installing the throttle valve, since the end portion of the valve plate does not need to be tapered and sharpened.
Another object of the present invention is to provide a vehicle throttle valve in which a predetermined clearance space is formed when the valve plate is in the flow path closing position, thereby reducing the phenomenon that the valve plate is stuck on the inner surface of the throttle body.
A throttle valve for a vehicle according to an embodiment of the present invention includes a throttle body having a passage for transferring sucked vehicle outside air to an engine side and having a step portion at an inner side thereof and a throttle body installed axially rotatably on the throttle body, And a valve plate that adjusts the cross-sectional size of the flow path and contacts the step portion to close the flow path.
In this case, it is preferable that the valve plate is in surface contact with the step portion to close the flow path.
In addition, when the valve plate is in contact with the step portion, it is preferable that the end portion of the valve plate and the inner surface of the throttle body are spaced apart from each other to form a clearance space.
As described above, the throttle valve for a vehicle according to the present invention does not need to be tapered and sharpened at the end portion of the valve plate, thereby reducing the possibility of wear and damage to the inner surface of the throttle body due to repeated operation of the valve plate.
In addition, the vehicle throttle valve according to the present invention does not need to have a tapered and sharpened end portion of the valve plate, thereby reducing the risk of injury to the user when assembling or installing the throttle valve.
Further, in the throttle valve for a vehicle according to the present invention, when the valve plate is in the flow path closing position, a predetermined clearance space is formed to reduce the phenomenon that the valve plate is stuck to the inner surface of the throttle body.

As described above, the vehicle throttle valve according to the present invention reduces the possibility of wear and damage of the inner surface of the throttle body due to repeated operation of the valve plate, reduces the risk of injury to the user during assembly or installation of the throttle valve, Thereby reducing the phenomenon that the valve plate is stuck on the inner surface of the throttle body.
As described above, the present invention has been described with reference to the embodiments shown in the drawings. However, it should be understood that the present invention is by way of example only and that various modifications and equivalent embodiments are possible on the basis of common knowledge in the art . Therefore, the true technical protection scope of the present invention should be determined based on the specific contents of the above-mentioned invention in accordance with the claims to be described below.
