Abstract

756,000. Valves. THOMASSEN, T. May 13, 1954, No. 14009/54. Class 135. A screw-down type of valve is provided with a jumper 6 of natural or synthetic rubber with an operative face shaped as a cone having an apex angle of 90 degrees, and with a cylindrical guiding stem 4 projecting from the upper end of the jumper. A metal washer 5 is interposed between the upper end of the jumper and the lower end of the threaded operating spindle 2.
