Abstract
Disclosed is an opening/closing valve including a valve body defining a passage, through which a fluid flows in a first direction, a solenoid coil mounted on the valve body along the first direction to surround the passage on an outside of the passage, and a valve disk including a magnetic substance and that is rotated on the passage to open and close the passage with the solenoid coil.
Claims18
An opening/closing valve comprising:
- a valve body defining a passage through which a fluid can flow in a first direction;
- a solenoid coil mounted on the valve body along the first direction to surround the passage on an outside of the passage;
- and
- a valve disk including a magnetic substance, the valve disk rotatable within the passage to open and close the passage with the solenoid coil;
- wherein the valve disk is rotatable about a rotary shaft extending in a second direction that is perpendicular to the first direction, the valve disk being rotatable between a closing position and an opening position;
- wherein the opening/closing valve is configured so that flow of the fluid flowing through the passage is blocked when the valve disk is in the closing position and the flow of the fluid flowing through the passage is allowed when the valve disk is in the opening position;
- wherein the valve disk is rotatable in a first rotational direction from the opening position to the closing position;
- wherein an inner peripheral surface of the valve body defines the passage;
- and
- wherein the valve body comprises a guide rib protruding from the inner peripheral surface of the valve body to prevent the valve disk from being rotated from the closing position in the first rotational direction.

An opening/closing valve comprising:
- a valve body defining a passage through which a fluid can flow in a first direction, wherein an inner peripheral surface of the valve body defines the passage;
- a valve disk including a magnetic substance disposed at a location within the passage, the valve disk rotatable about a rotary shaft between a closing position and an opening position, wherein the rotary shaft extends in a second direction that is perpendicular to the first direction and wherein the opening/closing valve is configured so that flow of the fluid flowing through the passage is blocked when the valve disk is in the closing position and the flow of the fluid flowing through the passage is allowed when the valve disk is in the opening position;
- a solenoid coil mounted outside the passage to surround the location within the passage in which the valve disk is disposed;
- and
- a seat member configured to seat the valve disk between the inner peripheral surface of the valve body that defines the passage and the valve disk at the closing position;
- wherein the valve body comprises a stopper configured to protrude from the inner peripheral surface of the valve body to prevent the valve disk from being rotated in a first rotational direction in which the valve disk is rotated from the closing position to the opening position at the opening position;
- wherein the seat member comprises a seat surface configured to be inclined toward an inside of the passage with respect to the first direction, when viewed in the second direction, to prevent the valve disk at the closing position from being rotated in the first rotational direction, in which the valve disk is rotated from the opening position to the closing position;
- and
- wherein the valve disk includes a contact surface formed to correspond to the seat surface to contact the seat surface at the closing position.

- wherein the valve disk is rotatable about a rotary shaft extending in a second direction that is perpendicular to the first direction;
- wherein the valve disk is rotatable between a closing position and an opening position;
- wherein the opening/closing valve is configured so that flow of the fluid flowing through the passage is blocked when the valve disk is in the closing position and the flow of the fluid flowing through the passage is allowed when the valve disk is in the opening position;
- wherein the valve disk comprises a first part and a second part that are divided by the rotary shaft;
- wherein the first part is movable to a downstream side of the passage when the valve disk is rotated from the closing position to the opening position;
- wherein the second part is movable to an upstream side of the passage;
- and
- wherein the first part includes a magnetic substance of a first pole and the second part includes a magnetic substance of a second pole that is an opposite pole to the first pole.
