Dual disc spring

Abstract

A dual spring includes a pair of conically-shaped spring sections, which are joined at a common fulcrum. One of the spring sections is disposed radially inward from the fulcrum and the other of the spring sections is disposed radially outward from the fulcrum. Both of the conical sections open axially in the same direction relative to the fulcrum section.

1 . A dual torque transmitting with a dual acting spring comprising; 
 a first piston member;    a second piston member:    a first conical spring section;    a second conical spring section;    a fulcrum section joining said first and second conical spring sections;    means for positioning said fulcrum section at a stationary position; and    said first conical spring section extending outward from said fulcrum section to engage said first piston member and said second conical spring section extending inward from said fulcrum section to engage said second piston member.    
   
   
       2 . The dual torque transmitting with a dual acting spring defined in  claim 1  further comprising: 
 one of said conical spring sections having a plurality of castellations.    
   
   
       3 . The dual torque transmitting with a dual acting spring defined in  claim 1  further wherein: 
 both of said first conical spring section and said second conical spring section opens in the same axial direction relative to said fulcrum section.
