Abstract
930,821. Stuffing-box substitutes. H. SCOBEL. Oct. 22, 1959 [Oct. 29, 1958], No. 35799/59. Class 122 (5). A seal employing two relatively-movable members 5, 10, Fig. 1, having their coacting surfaces 7, 9 urged towards one another by springs 8 has one or more passages leading towards and terminating at one of these surfaces for the passage of a pressurized lubricating medium, the flow of which is substantially constricted so that the two surfaces are forced apart to form a very small gap which avoids direct contact between the surfaces and allows the flow of medium into the gap. As shown applied to a rubbing-collar type seal, the surface 9 is formed on a ring 10 secured to a housing 11 and coacts with the surface 7 formed on a ring 5 which is slidably mounted on a ring 3 secured to a shaft 1 and loaded by the springs 8. The lubricating medium is fed through one or more ports 15 leading to the bottom of a groove 12 which receives a porous ring or segments 13 formed of carbon, ceramic material or sintered metal and constituting the constricting means for the medium as it passes to the surface 9. In the modification shown in Fig. 2, the porous ring 17 is located above a shoulder on the ring 10 so as to provide a gap 21 for the entry of the lubricating medium and the outer surface of the ring 17 is sealed off by an impermeable layer 18; this arrangement may be further modified by dispensing entirely with the layer 18 or providing it only on the lower portion of the ring or by locating the ring 17 so as to dispense with the gap 21. In a further modification, the lubricating medium is fed into the gap through drilled holes, slits or grooves serving as constricting means instead of the porous ring. If desired, the lubricating medium may be fed through passages leading into both the contacting surfaces 7, 9. The lubricating medium may be a gas or liquid and either the same as that being sealed off as is the case in the example shown in Fig. 1, or a separate medium which is then supplied by a pump and serves as a barrier seal in the gap between the surfaces 7, 9.
