Abstract
A low-resistance, liquid-tight seal for use in a valve having a nozzle that telescopes into an axial fluid passage in a valve body. The nozzle has a peripheral portion of reduced diameter near one end thereof for supporting a flat annular seal. The inner edge of the annular seal grips the nozzle while the outer portion of the seal undergoes a flip-flop action against the inner wall of the valve body as the nozzle moves in an out of the valve body. A closure can be provided for the nozzle which is opened by movement of the nozzle into the valve body and closed by the return motion of the nozzle. An improved valve and bottle-filling machine is provided for containers with low-crush resistance. The annular flip-flop seal provides a low resistance to movement when a container is used to push the nozzle into the valve body opening the fluid passage for filling the container.
