Abstract
1,237,943. Face seals. KOMBINAT PUMPEN UND VERDICHTER VEB. 28 Oct., 1968, No. 50960/68. Heading F2B. A sealing ring has a sealing face 1 for contacting a counter-ring which is normal to the ring axis and formed with circumferentially-spaced radially-inclined bevelled surface portions 2. In a modification, Figs. 3 and 4 (not shown), the bevelled portions (3) are on the inner periphery of the ring. In the embodiment shown in Figs. 5 and 6, an annular groove 5 divides the sealing face into an inner surface 5 and an outer bearing surface 7 formed with bevelled portions 2 communicating by radial ducts 4 with the groove 5. In use fluid fed to the groove 5 through holes (not shown) is urged outwardly by centrifugal force through the ducts 7 and serves for lubricating and/or cooling.
