Patent number: 5694771Abstract: The variable speed drive mechanism includes an input member (17) and an output member (18), each rotatable within a housing (11) filled with fluid. The input and output members each have helical vanes (26) that are in a close running fit with sleeves (21, 22) within the housing.

Patent number: 3992880Abstract: A fixed geometry torque converter having variable power absorption capacity by provision of a secondary fluid flow path which introduces fluid at the trailing edge region of the stator vane adjacent the impeller and at a direction normal to the primary flow of fluid from the turbine passing across the stator to return to the impeller. The rate of this secondary fluid flow is selectively varied to alter the direction of the primary flow of fluid and thereby selectively vary the power absorption capacity of the torque converter. In combination with a fluid turbomachine as utilized in aircraft systems, the variable capacity torque converter is arranged in the power drive train so as to load the turbomachine. By selectively varying the power absorption capacity of the torque converter in relation to prevailing ambient conditions, a greater amount of the power output capacity of the turbine machine may be utilized at various ambient conditions without causing stalling of the turbine machine.Type: GrantFiled: August 7, 1975Date of Patent: November 23, 1976Assignee: The Garrett CorporationInventor: Andrew R.
