This patent covers a V-ring packing for valve stems. The V-rings have a non symmetrical geometry with a longer leg to the V on the inside diameter against the shaft. The base ring is symmetrical and the header has more offset than the V-rings. The purpose is to increase the radial loading of the V-r
of anti-rotation devices linked to the seal housing. The static sealing between the side of each carbon segment and the seal housing allows sufficient radial movement to accommodate shaft radial excursions. The endurance cycle and wear results are shown in Figure 13. The air leakage of approximate
A seal arrangement for the fitting of a balljoint boot to a steering knuckle is described. An L-section, metal ring forms an interference fit with the shaft. The radial flange has an integral elastomer seal that seals against the flange of the joint. The boot itself seals against the outside diamete
