Abstract

911,780. Valves. AUDCO Ltd. March 22, 1961 [Jan. 5, 1960], No. 314/60. Class 135. A rotary conical cock 11 has sealing rings 15 at each end in the plug or casing, is pulled into its socket by Belleville washers 22 surrounding a plug extension 16 which provides an inlet 20 for lubricant acting in grooves 18, 19 and behind the sealing rings at 14. The washers may be replaced by a helical spring and the large end of the plug carry a handle pointer and a lubricating plunger.
