Definitions

  • FIG. 2 illustrates a view taken on line IIII of FIG.
  • a means such as a bearing lug 8 is secured to the center of the lid 1 by screws 7 and extends with clearance around a shaft 9.
  • the shaft 9 rests in a bifurcated end 10 of a one-armed lever 11 onan axis spaced from the lid 1 and is secured against lateral movements by screws 12.
  • Several convolutions of a spring 13 extend around the shaft 9 on both sides of the lug 8 with the free ends of the spring 13 bearing on the sides of the bifurcated end or fork 10. The function of the spring 13 is to take up the clearance in the lid mounting on the shaft 9.
  • Tee abutment rollers 14 previously referred to are disposed in the casing 2 in the pivot area, which extends over approximately 45 in the views in side elevation, of the lever 11 which is operated by rotation of the shaft 16. That is, the rollers 14 are positioned in the path of movement of the lid 1 between the closed and open positions.
  • the rollers 14 are mounted by means of washers 27 on two spindles 26 which extend through the casing 2 and are welded thereto in gas-tight fashion, location of the rollers 14 being by way of split pins 28.
  • the main function of the rollers 14 is to ensure that when the lid 1 opens, in the case shown in FIG.
  • the arm 18 is so mounted on the shaft 16 relatively to the lever 11 as to be in the position shown in FIG. 4a when the lid 1 is in the open position and to be in the end position shown in FIG. 4b when the lid is in the closed position. Consequently, when the shaft 16 rotates in the area of operation, the arm 18 passes through the lowest point of its travel, the chain 38 abutting the cam 39 when the lid is in the open position. Consequently, difierent lever arms r and s arise in the open position and in the closed position for the closing torque which the spring 20 applies to the lever 11, i.e. such torque is considerably greater for the closed position than for the open position of the lid 1.
  • the arrangement of the arm 18 relative to the lever 11 and to the spring 20 increases the action of the spring 20 in the closing direction or, for a given force of the spring 20, enables the dimensions of the spring to be reduced considerably.
  • the spring elongation which occurs only during operation and whose peak value is determined by the dimensions, shape and properties of the spring, is relatively small and corresponds just to the difference in length between the end position and the lowest point of travel of the arm 18.
  • the lever arm s which is increased in the closed position by this constructive feature, acts correspondingly.
  • the annular resilient, e.g. rubber, sealing element 5 which is secured by way of a pine cone-shape bottom part in a groove 6 in flange 3, has a base 43 which bears on the flange 3 on both sides of the groove 6 and which carries a W-shaped cross-section part.
  • the outer lips 44 of the W-shaped portion are relatively thin and very resilient and ensure a gas-tight seal even though the pressures applying the lid 1 to the flange 3 are relatively small.
  • a much stiffer central part 45 becomes operative, more particularly at high pressures which arise because of the pressure of the medium in the line acting in addition to the force of the spring 20.
  • the central part 45 therefore provides an extra safeguard that the required gas-tightness is provided at high pressure.
  • a first adjusting means for moving said lid from a closed position adjacent said flange to an open position spaced from said flange, said adjusting means including a pivotally mounted operating shaft passing through said casing, a one-armed lever secured to said shaft within said casing, and means for pivotally mounting said lid about an axis at one end of said lever with said lid spaced from said lever;
  • a second adjusting means for moving said lid from said open position to said closed position
  • abutment rollers mounted in said casing on opposite sides of said lever in the path of movement of said lid between said closed position and said open position.
  • said second adjusting means includes at least one pivot arm connected to said operating shaft for movement therewith.
  • said second adjusting means includes a spring secured to said casing at one end, a cable-like pull element connected to and between an opposite end of said spring 6 and said pivot arm.
  • said resilient seal includes a W-shaped cross-section at one end facing said lid.
