Valve apparatus

A valve apparatus adapted for installation within a fluid conveying conduit comprising:

• an elongated body means having a pair of axially spaced opposed ends and a flow passage means which extends therebetween and includes an external peripheral portion of said body means located axially intermediate said opposed ends;
• a resiliently deformable ring means encompassing said body means with and inner peripheral portion thereof in peripheral sealing engagement with said external peripheral portion of said body means to close said fluid flow passage means;
• said resiliently deformable ring means having an outer peripheral portion which is adapted to engage the interior periphery of such a fluid conveying conduit in continuous circumferentially extending sealing engagement therewith;
• and
• said resiliently deformable ring means being operable upon compressive deformation thereof in a direction generally radially inward with respect to the longitudinal axis of said body means to open said fluid flow passage means radially intermediate said inner peripheral portion thereof and said external peripheral portion of said body means to permit fluid flow through said valve within said fluid flow passage means.
