Definitions

  • Figure 2 is an exploded perspective view
  • the spider spring 10 which is m the form of an outer annular portion 54 with a plurality of generally radially inwardly projecting legs 35 ( Figure 2) , is sandwiched between end plate 11 and a collar 36 at the base of actuating pm 31, the pm projecting through the center of the spider spring and an opening 37 m the center of end plate 11.
  • the legs 35 are inclined slightly towards the collar 36 so as to apply a force on the operating diaphragm 9 acting m the opposite direction to the fluid pressure P. By cutting off one or more of the legs 35, the spider spring pressure can be adjusted.
