Title:
ROTARY VALVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/057674
Kind Code:
A1
Abstract:
The present disclosure describes a rotary valve device that makes it possible to suppress exhaust gas leakage with a simple configuration, and to significantly reduce the effort of maintenance. This rotary valve device comprises: a casing; a rotor provided in the casing so as to be rotatable around a rotational shaft that is disposed inside the casing and extends in the horizontal direction; and a sealing part. The sealing part includes a first sealing member that is annular in shape and provided on the casing, and a second sealing member that is cylindrical in shape and provided on a side plate of the rotor. The first sealing member is fixed to the casing on the outer peripheral edge side thereof, and is opposed to an outer peripheral portion of the side plate of the rotor. The second sealing member extends along an extending direction of the rotational shaft between the side plate of the rotor and the first sealing member, and has one end side fixed to the side plate of the rotor and the other end side having a predetermined space from the first sealing member.
