Abstract: A variable flow device includes a body supporting a first orifice and a second orifice, and a drive mechanism. The variable flow device further includes a first valve actuator coupled to the drive mechanism and linearly shiftable between a first open position and a first closed position, the first valve actuator incorporates a first valve stem including a first conical portion sized to symmetrically engage the first orifice when the first valve stem is shifted to the first closed position, and a second valve actuator coupled to the drive mechanism and linearly shiftable between a second open position and a second closed position, the second valve actuator incorporates a second valve stem including a second conical portion sized to symmetrically engage the second orifice when the second valve stem is shifted to the second closed position.
