    Abstract: A check valve (10) for controlling a flow of fluid by fluid pressure, comprising a housing (11) and a resilient flexible valve element (12) inside the housing (11), wherein the valve element (12) is formed as a hollow and longitudinally tapered body (16) with an open wide end (18) and a closed narrow end (19), and wherein the wide end (18) of the valve element (12), in a default configuration, engages an inner surface of the housing (11) to close the check valve (10) and is deformable by a predetermined fluid pressure from the inlet (13) to open the check valve (10). The tapered body (16) comprises a radially outwardly projecting flange (17) at the wide end (18), which flange comprises a curved outer surface portion (20) having a degree of curvature of 85 to 95 degrees, wherein the housing (11) is formed with a protrusion (29) having a curved surface (30) for engaging the curved outer surface portion (20) of the flange (17).

    Abstract: A radial flow non-return fluid valve assembly is disclosed which comprises a housing (12) including a cylindrical wall (13), and a circumferentially elongated opening (16), or a row of circumferentially spaced openings (16), in the wall (13) for enabling fluid to flow from an entrance side to an exit side of the wall (13), and a cylindrical spring collar (18) of circular cross section located on the exit side (14) of the wall (13). The resilience of the collar (18) acts in a direction to urge the collar (18) into contact with the exit side (14) of the wall (13) so as to obstruct the opening(s) (16) when the fluid pressure at the exit side is equal to or greater than the pressure on the entrance side, and the collar (18) is deformed when the fluid pressure at the entrance side exceeds the fluid pressure at the exit side to uncover the opening(s) (16) in order to allow fluid to flow through the openings in the wall (13). In the invention, one circumferential end of the collar (18) is anchored to the housing to leave a single span of the collar (18) free to separate from the exit side (14) of the wall (13), the length of which span extends over at least 60% of the circumferential length of the exit side (14) of the wall (13).

    Abstract: The present invention is directed to a pressure-responsive valve assembly (20, 120, 220) which functions in the nature of a check valve to control fluid flow across the assembly. The assembly (20, 120,220) includes a valve body (24, 124, 224) which defines first and second internal flow passages (32, 24; 132, 134; 232, 234), and includes a valve seat (36, 136, 236) through which at least one flow port (38, 138, 238) extends for joining the first and second passages (32, 34; 132,134; 232,234) in fluid communication with each other. A flexible, resiliency dθformable valve member (28, 128, 228) is positioned in operative association with the valve seat (36, 136, 236), and can be deflected, in response to a sufficient pressure differential, to move out of sealing engagement with the valve seat (36, 136, 236), to thereby permit fluid flow through the valve assembly (20 120, 220).

    Abstract: A drip irrigation line includes a plurality of emitter units (20) secured within a water supply tube (21) such that each emitter unit (20) defines with the tube (21) a flow-control passageway having an inlet port (23) communicating with the interior of the water supply tube (21) and an outlet port (24) communicating with a water discharge opening (22) in the water supply tube (21). Each emitter unit (20) includes a one-way valve (50) at one of the ports (23, 24). Such port (23, 24) has an opening circumscribed by a cylindrical boss (40, 70), and the one-way valve (50) thereat includes a cap (51) having a skirt (52) of elastomeric material normally engaging the outer surface of the cylindrical boss (40, 70) to block reverse water flow into the flow-control passageway, but is deformable under water pressure to permit forward flow from the tube (21) interior into the flow-control passageway.
