<p>The present invention relates to a multi-port valve capable of being used under high pressure circumstances. According to the present invention, as an elastic force of a spring is applied to a state wherein pistons are evenly in contact along a circumference of a rotor, the rotor is not left from a fixated body. Moreover, as sealing is performed only in a state wherein a connection hole faces a certain piston as the rotor is rotated, a sufficient sealing effect can be obtained even if an elastic force of the spring is relatively weak. Furthermore, friction load is reduced using the spring which has a low elastic force, thereby significantly reducing wear of the rotor or the pistons.</p> |
