ABSTRACT:
A valve comprises a tube having an inner wall surface inwardly stepped to provide a ribbed peripheral seat in a plane perpendicular to the axis of the tube and between inlet and outlet chambers bounded by tube lengths of relatively greater and relatively smaller cross-sections respectively. A washer disk or resilient material sized to fit with peripheral clearance within the inlet chamber is held spaced from the peripheral step base by ribs outstanding therefrom.
