Abstract
A valve assembly includes a housing having at least one valve orifice for fluid flow therethrough, and a valve member which moves between a fully closed position and a fully open position, respectively, closing and opening said valve orifice. The valve orifice has a clearance surface forming an auxiliary valve passageway selectively enabling flow communication therethrough in an intermediate position of the valve member between said fully open and fully closed positions, and in the intermediate position the valve member partially obstructs the valve orifice so that the passageway provides attenuated fluid flow communication through the valve orifice relative to fluid flow communication in the fully open position of the valve member. A manually controlled actuator enables limited displacement of the valve member between the fully closed position and the intermediate position for the attenuated flow communication through the valve orifice. The valve assembly can be one of dual valves for particular use as a surgical trumpet valve assembly housed within a two-part housing.
