一方向バルブとそのバルブを使用する装置及び方法
Document Type and Number:
Japanese Patent JP2008522906
Kind Code:
A
Abstract:
A device including a valve body defining a first passageway, a valve seat, and a flow aperture extending through the valve body and coupled in fluid communication with the first passageway. A valve member formed of an elastic material overlies the valve seat, defining a normally closed, axially-extending valve opening therebetween. The valve member is movable between a normally closed position engaging the valve seat, and an open position with at least a segment of the valve member spaced away from the valve seat to connect the valve opening in fluid communication with the flow aperture. A hermetically sealed variable-volume storage chamber stores therein multiple portions of the fluid and is connectible in fluid communication with the one-way valve assembly. A pump pumps discrete portions of fluid from the chamber, through the flow aperture and through the valve opening to dispense the portions of fluid therethrough.
