Abstract
A valve mechanism includes a housing, a plate-shaped valve body, a valve positioning member, and a drive valve moving mechanism. The valve positioning member causes the valve body to face the valve seat via a predetermined gap with respect to the valve seat. The drive valve moving mechanism causes the gap between an inner circumference of the valve body and the valve seat to be variable by moving the drive valve in a direction of approaching the valve seat and elastically deforming the valve body in a direction that the inner circumference of the valve body approaches the valve seat.
Claims9
A valve mechanism, comprising:
- a housing including a valve seat that is formed at the outer side, in the radial direction, of an opening at one end of a fluid channel;
- a drive valve arranged to be movable in a direction of being contacted to and apart from the valve seat;
- a plate-shaped valve body made of an elastic material having an opening through which fluid passes as being arranged between the valve seat and the drive valve;
- a valve positioning member that causes the valve body to face the valve seat via a predetermined gap with respect to the valve seat;
- and
- a drive valve moving mechanism that causes the gap between an inner circumference of the valve body and the valve seat to be variable by moving the drive valve in a direction of approaching the valve seat and elastically deforming the valve body in a direction that the inner circumference of the valve body approaches the valve seat.
