US Patent:

41778855, Dec 11, 1979

Filed:

Oct 13, 1978

Appl. No.:

5/951090

Inventors:

Phillip J. Ross - Brownsburg IN

Assignee:

General Motors Corporation - Detroit MI

International Classification:

F16D 4706

US Classification:

192 33

Abstract:

A torque converter and multi-disc lock-up clutch has a pair of clutch discs splined to the input shell of the torque converter, a friction disc splined to the clutch piston intermediate the clutch discs and a friction pad secured to the clutch piston. The clutch piston is drivingly connected with the turbine of the torque converter. The clutch is controlled by fluid under pressure delivered to the torque converter such that during disengagement, the fluid passes between the clutch discs and the friction disc prior to entering the torque converter.

Assignee:

General Motors Corporation - Detroit MI

International Classification:

F02C 718
F02C 726

US Classification:

60 3967

Abstract:

A combustor assembly for an automotive gas turbine engine includes a continuously ignited, pilot flame tube supported on a combustor dome immediately downstream of an inlet fuel nozzle and air swirler assembly. The pilot flame tube has an air swirler and fuel nozzle supported on an interior bulkhead and air is supplied upstream of the bulkhead and through a double-walled porous tube assembly for cooling wall portions of the flame tube exposed to the flame front within the combustor and wall portions thereof exposed to a pilot flame formed within the flame tube.

General Motors Corporation - Detroit MI

International Classification:

F16H 4704

US Classification:

74687

Abstract:

A hydromechanical transmission in which the first and second drive ranges are input-split drives. In one embodiment the transmission includes a hydrostatic portion comprised of two hydraulically interconnected, variable displacement, hydraulic pump-motor units and two planetary gear sets which are controlled by a brake and a clutch to provide the two ranges. In another embodiment a third planetary gear set and a second clutch are added to provide increased torque coverage in first range and also provide a third drive range. In both embodiments the speed ratio within the drive ranges is varied by controlling the displacement ratio between the pump-motor units. The shifting from one drive range to another occurs at synchronous speeds, thereby reducing the shift energy absorption required in the clutches and brakes.

Appl. No.:

6/135656

Inventors:

Assignee:

General Motors Corporation - Detroit MI

International Classification:

G05D 1310
F16D 2512

US Classification:

74752C

Abstract:

In a transmission having input and output shafts drivingly connected by fluid pressure operated ratio establishing devices an improved centrifugally actuated valve is provided to disestablish the driving connection maximum angular velocity of the input shaft. The valve includes a sphere disposed in a stepped bore which sphere is spring biased to a closed position for normal operation and which shifts in response to centrifugal force to an open position in a fluid flow path thereby exhausting the drive establishing device and also being flushed of any contaminants.
