Abstract
The present air intake control valve includes a valve body and a seal portion being elastically deformable to seal between an inner wall surface of an air intake port and the valve body. The seal portion is formed in a bending configuration including a first hinge portion and a second hinge portion each serving as a supporting point upon elastic deformation of the seal portion. One of the first hinge portion and the second hinge portion is arranged at an upstream side of the air intake port and the other of the first hinge portion and the second hinge portion is arranged at a downstream side in a state where the valve body is at a closed position.
Claims9
An air intake control valve comprising:
- a valve body provided at an air intake port to rotate around a rotation shaft between an open position and a closed position;
- and
- a seal portion arranged at one side and the other side of an outer peripheral portion of the valve body in a direction orthogonal to the rotation shaft of the valve body and sealing between an inner wall surface of the air intake port and the valve body by making contact with the inner wall surface of the air intake port in a state where the valve body is at the closed position, the seal portion being elastically deformable,
- the seal portion being formed in a bending configuration including a first hinge portion and a second hinge portion each serving as a supporting point upon elastic deformation of the seal portion,
- one of the first hinge portion and the second hinge portion being arranged at an upstream side of the air intake port and the other of the first hinge portion and the second hinge portion is arranged at a downstream side of the air intake port in the state where the valve body is at the closed position.
An air intake apparatus comprising:
- a surge tank and an air intake port arranged at a downstream of the surge tank;
- and
- an air intake control valve provided at the air intake port, wherein
- the air intake control valve includes:
- a valve body rotating around a rotation shaft between an open position and a closed position;
- a seal portion arranged at one side and the other side of an outer peripheral portion of the valve body in a direction orthogonal to the rotation shaft of the valve body and sealing between an inner wall surface of the air intake port and the valve body by making contact with the inner wall surface of the air intake port in a state where the valve body is at the closed position, the seal portion being elastically deformable,
- the seal portion being formed in a bending configuration including a first hinge portion and a second hinge portion each serving as a supporting point upon elastic deformation of the seal portion,
- one of the first hinge portion and the second hinge portion being arranged at an upstream side of the air intake port and the other of the first hinge portion and the second hinge portion being arranged at a downstream side of the air intake port in the state where the valve body is at the closed position.
