<p>A movable valve element (20) in which a communication path (21) is formed is provided so as to rotate about a predetermined shaft center (M). A first valve seat (10) opposing the movable valve element (20) on one side of the movable valve element (20) in a direction along the shaft center (M) is provided. In the first valve seat (10), a plurality of connection ports (C, D, E, S) are formed. A second valve seat (30) opposing the movable valve element (20) on a side opposite to the first valve seat (10) is provided. Each of the first and second valve seats (10, 30) is arranged apart from the movable valve element (20) with a predetermined clearance. The communication path (21) penetrates the movable valve element (20) in the direction along the shaft center (M). A first sealing member (40) is arranged around the communication path (21) so as to seal a space inside the communication path (21) from a space defined by the clearance on a side close to the first valve seat (10), and a second sealing member (41) is arranged around the communication path (21) so as to seal the space inside the communication path (21) from the space defined by the clearance on a side close to the second valve seat (30).</p> |
