摘要： The improved control and purge valve of the present invention is useful for the atomization of heavy fuel oil for combustion. The present control and purge valve is operable between closed, purging, and open positions, and includes an elongated valve body having a disc carrier disposed therein. The disc carrier preferably comprises a plurality of closure and orifice means thereon for opening or closing internally disposed steam exit, steam bypass exit, and oil exit ports to effect the closed, purging, and open positions of the valve of the present invention.

摘要： The present invention is directed to an improved wear compensating stem sealing apparatus. The elements thereof include a unitarily formed or separably formed O-ring separator disposed upon a valve stem. A first, or "wiper" O-ring is disposed on the stem in a space provided on the O-ring separator. A second (and in some embodiments, a third) O-ring is disposed about the stem in a similar space on the O-ring separator above the level of the first O-ring. The second and/or third O-ring provide a subsequent sealing of the stem from pressurized fluid migrating upwardly upon wear of the first O-ring. The first O-ring may be made of a material which will wear more rapidly and/or wipe more efficiently than the second and/or third O-ring, or provide less radial squeeze, such that the second and/or third O-ring is subjected to increased compressive pressure from the pressurized fluid upon the wearing of the first O-ring.
