ABSTRACT:
The present invention provides an improved seal for a metering orifice between an orifice seal member and an orifice housing. The orifice housing includes first and second upper surfaces which are separated by an annular groove or notch, the first surface being adjacent a central bore and recessed from the second surface. The first surface is sealably engaged by a sealing surface provided by the orifice seal member. The orifice seal member includes a stem which is threadably received by the central bore, and which is surrounded by the sealing surface. Threadably mounting the orifice seal member to the orifice housing engages the sealing surface with the first surface and causes the first surface to be compressed, compensating for the derogatory effects of imperfections in the first surface, and, also, moving a cylindrical wall surrounding the central bore radially inwardly toward the central bore to allow the orifice seal member and the orifice housing to sealably engage thereby seal the central bore and allow fluid to only exit via the metering orifice. Alternate embodiments of the invention provide the first surface relatively above and relatively even with the second surface.
