Patent attributes
Disclosed herein is a valve apparatus for vehicles that is configured such that the sealability of a valve body can be markedly enhanced. The valve apparatus includes a valve body, a valve member and a sealing unit. The valve body is provided with at least two ports and has an internal space communicating with the ports. The valve member is rotatably installed in the internal space so as to open or close the ports. The sealing unit is provided to seal at least one of the ports. The sealing unit includes a sealing body airtightly installed on an inner surface of the corresponding port, and at least one elastic element integrally provided on a first end of the sealing body. The elastic element axially applies elastic force to the sealing body so that a second end of the sealing body comes into airtight contact with the valve member.
