Abstract

429,796. Lubricating valves. AMERICAN CAR & FOUNDRY CO., 30, Church Street, New York, U.S.A. March 10, 1934, No. 7711. Convention date, March 15, 1933. [Class 12 (ii)] A plug cock is sealed and lubricated by lubricant forced by the ram 30 in the stem through a transverse passage 20 to the annular channels 18 and 22, and to the annular groove 48 through the longitudinal grooves 40, 44, on the plug surface. These are connected to the channel 22 through channels 38 on the valve body, and through constricted passages 52 in the plug surface. A spring 58 holds the surface 24 against the valve body. Excessive lubricant in the channel 18 escapes into the space 16. A leak passage 64 connects the space 56 to the plug bore 6.
