A fluid pressure operated friction coupling comprising a multiple friction disc assembly having a single piston actuator (85,132) and having first and second springs (94,134,104,136) operatively configured and arranged in response to pressurization of the piston actuator to selectively engage first and second sets of plates and friction components (100,102,126,128) for varying the gain of the coupling. <IMAGE> |
