Stemless bantam valve

Claim 1

A stemless valve which comprises: an elongated cylindrical housing with an axis along its length, said housing including an inlet end and an open end opposite said inlet end with each end coaxially aligned with said housing; a cylindrical valve body extending into said open end of said housing with its linear axis in coaxial alignment with said housing, said valve body including an inner end toward said inlet end of said housing and an outer end extending from said open end of said housing; an axially extending inlet passage in the inner end of said valve body in coaxial alignment with said housing and extending toward the outer end to a first passage across the diameter of said valve body perpendicular to the axis thereof; an axially extending outlet passage in said valve body extending from the outer end of said valve body toward said inlet passage in coaxial alignment with said housing to a second passage across the diameter of said valve body perpendicular to the axis thereof with said first and second passages spaced from each other axially along said valve body and parallel with each other; a first O-ring seal between said housing and said valve body on the inlet side of said first passage in said valve body and fixed within a first cylindrical cutout in said valve body; a second O-ring seal between said valve body and said housing and located between said first and said second passages in said valve body within a second cylindrical cutout in said valve body to prevent fluid leakage; a third O-ring seal between said valve body and said housing on the outlet side of said second passage in said valve body and fixed within a third cylindrical cutout in said valve body to prevent fluid leakage, said housing including opposing cutouts in the inner wall thereof in the area between said second and third O-ring seals within said valve body near said second passage in said valve body; a threaded cap enclosing the upper end of said inner end of said valve body, said threaded cap including a passage therein coaxial with said housing and extending from said axially extending inlet passage in said valve body to a passage across the diameter thereof perpendicular to said coaxial passage therein with said coaxially aligned passage opening toward said inlet in said valve body; and a thin, interchangeable element secured in place between said threaded cap and the inner end of said valve body with said interchangeable element including an orifice therein coaxial with said housing with said orifice aligned with the axial passage in said cap and the inlet passage in the inner end of said valve body, said interchangeable element controlling fluid flow between said inlet in said housing through said passages in said cap to said inlet passage in said valve body, whereby said orifice in said interchangeable element and the position of said valve body in an axial position relative to said cutouts in said housing controls fluid flow through said stemless valve.
