Abstract

233,848. Hopkinson, R. A., and Hopkinson & Co., Ltd., J. April 8, 1924. Leakage, preventing. - In valves to prevent leakage past the valve spindle when the valve is fully open, the spindle a is formed with a flat collar c adapted to abut against a seating face formed on a ring d secured in the valve cover e or in the base of the stuffing-box secured in the said cover. The flat face c allows lateral displacement of the valve spindle so that the pressure within the valve can always be isolated from the packing gland. Specifications 14499/94, 13082/98, and 24226/02 are referred to.
