Quick-disconnect valve
First Claim
1. A valve for permitting flow of a fluid therethrough when actuated by a nozzle, and otherwise preventing flow of fluid therethrough, the valve comprising:
- a fluid passageway bounded by a wall; and
a relatively flat resilient seal member having an edge and a central portion, the seal member being disposed transversely to the fluid passageway such that the edge of the seal is normally disposed against the wall of the fluid passageway so as to prevent the flow of fluid past the seal member, and such that, when the central portion of the seal member is urged in a direction generally parallel to the fluid passageway, the seal member deforms such that the central portion is displaced and such that the edge of the seal member separates from the wall so that fluid may flow through the passageway by passing between the wall and the seal member.

Abstract
A normally-closed valve that can be easily connected and disconnected. Disposed in the fluid passageway through the valve is a flexible, resilient disk and a pin mounted adjacent to the disk. The disk is mounted in a wide portion of the passageway and is held in place by the narrow portions of the passageway. The disk fits snugly into the passageway so that the edge of the disk forms a seal with the wall of the passageway. A nozzle is inserted into the passageway and urges the pin against the disk, causing the disk to deform. When the disk deforms, its effective diameter decreases, and its edge separates from the passageway wall, permitting fluid to flow through the valve. The narrow sections of the passageway wall have channels disposed therein for permitting flow when the disk is deformed. The pin also has channels on its surface to permit flow around it.
