Abstract
358,478. Pump valves. MELOTT, J., 2930, Walton Avenue, Los Angeles, U.S.A. June 30, 1930, No. 19831. Convention date, April 17. [Class 135.] Closure members, multiple-beat lift.-A check valve for slush or mud pumps having a conical metal to metal closure is provided with a seating ring 39, Fig. 4, of resilient material adapted to bear on a converse rim 22 of the valve seat with a yielding contact, and secured by a metal plate 50. The resilient ring may be provided with a leather facing 70, Fig. 6 and its periphery may be grooved, as shown, for additional flexibility. A flexible metal ring 72 with turned down edge 73 may be added to form an additional and yielding metal to metal contact with the seat, as shown ; this ring 72 may, if desired, be embedded in the seating ring 39. In closing, a fluid cushion is formed in an annular space between the valve and seat, and the slush is compressed in the annular space and gritty matter forced from the slush.
