Definitions

  • FIGs 3 and 4 schematically illustrate three different angular positions of the chute 24 under the action of the cap 58.
  • the position in solid lines is a medium position corresponding to a vertical orientation of the lever arm 64, in which the shoe 62 found in its highest position in the groove 60.
  • the positions in broken lines 24a and 24b of the chute correspond respectively to maximum and minimum inclinations of the chute, the last being the vertical position.
  • these extreme inclinations are obtained from the average inclination by relative rotation of the cap 58 relative to the bearing 42 either in one direction or in the opposite direction and accompanied by a descent of the skate 62 in the groove 60 of the cap 58.
  • the amplitude of rotation of the cap 58 necessary for the pivoting of the chute 24 from the vertical position to that of a maximum inclination 24a is less than 1 / 4 turn.
  • the sealing valve 30 is carried by the end of a lever arm 84 pivoting around the end of the fork 82, the other end of the lever arm 84 being actuated in the axial direction by the mechanism 80 to rotate the lever 84 around its point of attachment to the fork 82.
  • the opening of the sealing valve 30 first comprises an axial movement of the mechanism 80 to rotate the lever 84 anticlockwise in order to release the valve 30 from its seat 32.
  • the fork 82 is turned around the axis of rotation B to move the valve 30 in a rotary motion to a garage position. Closing the valve, of course, has the same phases in reverse.
