Abstract
A bi-directional flow valve for use in regulating flow of pressurized fluids in surgical instruments is disclosed. The valve comprises a valve body having an axial bore of variable radius, a plunger axially and slidably mounted within the bore of the valve body, a flange provided on the plunger for circumferentially engaging the bore at its narrowest point, a spring means for urging the flange against the bore at its narrowest point, and seal means to seal the gap between the plunger and the bore, and displacement means to move the plunger and flange out of contact with the bore so that fluid may pass through the bore and thus through the valve.
