Abstract

The present invention relates to a valve device for a vehicle, the valve device having the sealability for ports of a valve body greatly enhanced. A valve device for a vehicle, according to the present invention, comprises: a valve body having on the outer side thereof two or more ports and having an inner space for communicating with the ports; a valve member, rotatably provided in the inner space of the valve body, for opening and closing the ports; and a sealing means for sealing one or more of the ports, wherein the sealing means has sealing members, which are hermetically provided on the inner sides of the ports, and one or more elastic elements which are integrally provided on one end of the sealing member and, by applying to the sealing member elasticity in the direction of the axial line, bringing the other end of the sealing member into hermetic contact with the outer side of the valve member.

Description

technical field [0001] The present invention relates to a valve device for a vehicle used for fluid circulation in a vehicle, fluid flow restriction, and the like, and more particularly to a valve device for a vehicle capable of greatly improving the sealing performance of a valve body orifice. Background technique [0002] Vehicles have different types of valve devices inside, and these valve devices can distribute and control the flow of various fluids according to purposes such as engine cooling, interior space cooling and heating, and exhaust gas recirculation (EGR system). and even restrictions. [0003] On the other hand, among such different types of valve devices, a rotary valve (rotary valve) includes: a valve body having more than two orifices; Close 2 or more orifices. This type of rotary valve is mainly used in cooling water circulation circuits of internal combustion engines. [0004] As an example of such a rotary valve, US6315267B1 (hereinafter referred to ...
