Patent ID: 11043367

Abstract:
Provided is a valve 130 which requires only a small space for the open/close operation of an opening 113 in a partition wall. A sealing part 140 includes a sealing member 141 for sealing the opening by being pressed onto the partition wall around the opening. An urging means 144 urges the sealing member 141 against the opening when the sealing member 141 is in contact with the opening. A driving means 160 generates a driving force orthogonal to an opening central axis A which is an axis perpendicular to a partition plate 111 and passing through the center of the opening. A linkage 150, which is a Scott Russell linkage connecting the sealing part 140 and the driving means 160, converts the driving force of the driving means 160 into a driving force which is parallel to the opening central axis A and makes the sealing part 140 move along the same axis.
