Abstract
A fluid delivery valve for use in fluid conducting systems includes a rigid bracing member positioned within a hollow, flexible, resilient valve housing. By applying opposing lateral forces to the external surface of the housing near a widened portion of the bracing member, the valve housing deforms around the widened portion and the valve is actuated. Actuating the valve permits fluid communication between the inner chamber of the valve housing, and a channel which extends through an enlarged portion. The channels are sealed by the inner wall of the housing when the opposing forces are released. The fluid is thus selectively allowed to travel past the bracing member.
