Abstract:
A valve includes a housing defining therein a channel, a valve seat on an inner surface of the housing at a middle of the channel, a valve body member seated on and unseated from the valve seat to close and open the channel, and a stem spaced from the valve seat and rotatable around a first axis parallel with an opening surface of the valve seat. The valve body member and the stem respectively have a restricting hole and a restricting projection mutually slidably engageable to form a cam mechanism. The cam mechanism, in conjunction with rotation of the stem, reciprocates the valve body member between the seated position and the unseated position, and rotates the valve body member to be in a posture along a flow direction of a fluid flowing through the housing at the unseated position.

Claim (Index 3):
A valve comprising:\n a housing defining therein a channel; a valve seat provided to an inner surface of the housing at a middle of the channel; a valve body member configured to be seated on the valve seat to close the channel and unseated from the valve seat to open the channel; and a stem spaced away from the valve seat, the stem being configured to rotate around a first axis parallel with an opening surface provided to the valve seat, wherein the valve body member comprises a valve-body engagement portion and the stem comprises a stem engagement portion, the valve-body engagement portion and the stem engagement portion being configured to be slidably engaged with each other to form a cam mechanism, and a rotation range of the stem comprises: a first rotation range where the cam mechanism moves the valve body member in a direction substantially orthogonal to the opening surface of the valve seat while keeping the valve body member squarely facing the valve member; and a second rotation range where the valve-body engagement portion and the stem engagement portion are engaged to rotate the valve body member around the first axis by a predetermined angle.
