US Patent:

40859800, Apr 25, 1978

Filed:

Dec 13, 1976

Appl. No.:

5/750257

Inventors:

Earl W. Traut - Orlando FL

International Classification:

F16C 3336

US Classification:

308205

Abstract:

Radial and axial load bearing devices in which loads are transferred from a race through rollers to a second race, the races having projections which fit into recesses in the rollers, thus providing separation between the rollers and also avoiding sliding friction.

Appl. No.:

5/572384

Inventors:

Earl W. Traut - Orlando FL

International Classification:

F04B 2310
F01C 102
F01C 2116
F16D 3100

US Classification:

417204

Abstract:

A mechanism with only two dynamic components, in which rotating crank motion is converted to intermittent rotation of an elongate rotor within a generally triangular chamber and vice versa. When the rotor and chamber are enclosed, the mechanism becomes a positive displacement fluid pump or motor capable of converting rotational torque into fluid pressure and vice versa; a high volume of fluid moving through a small device at comparatively low shaft speed. Further modification of the mechanism permits the rotor to slide axially while rotating, resulting in a variable displacement rotary fluid pump or motor. Adaptations of the invention provide: shaft drives having continuously variable speed ratios; fluid energy transformers wherein flow and pressure may be continuously converted into variably different flow and pressure; and continuously variable, gearless automotive transmissions. Additional capabilities include efficient pneumatic motors, compressors, and external combustion engines.

Appl. No.:

Inventors:

Earl William Traut - Orlando FL

International Classification:

F04B 2310
F01C 102
F01C 2114

US Classification:

417204

Abstract:

A compact, rotary gas-operated motor having only two moving components, including valving. Pressurized gas causes an elongate rotor to rotate end-over-end within a generally triangular chamber and causes a crank to slide in a slot in the elongate rotor. A disk rotating with the shaft includes ports to admit pressurized gas and exhaust spent gas. The inlet port is shaped and positioned to provide early cut-off of inlet gas and provide up to 2:1 expansion ratio of the pressurized gas. Still earlier cut-off of inlet gas, at a location between the rotating disk and its housing, provides expansion ratios as high as 9:1. A movable guillotine may be used to provide continuously variable expansion ratios of from about 3:1 to 9:1.

Appl. No.:

Inventors:

Earl W. Traut - Orlando FL

International Classification:

F01C 102
F01C 2116
F03C 300
F04C 1504

US Classification:

418 24

Abstract:

An elongate rotor operated by a crank and rotating within a generally triangular chamber to act as a positive displacement pump or fluid motor. Sliding the rotor axially through a close-fitting hole in a plate which is free to move radially but not axially causes the displacement of the triangular chamber to vary. System fluid pressure may be used to vary the displacement.

Filed:

Aug 5, 1977

Appl. No.:

5/822093

Inventors:

Earl W. Traut - Orlando FL

International Classification:

G05D 1103

US Classification:

137 98

Abstract:

Linear motion fluid-actuated valves in which all elements are in rolling contact. Two major rollers are prevented from moving apart by a retainer belt, a separator roller depressing the belt between the two major rollers to prevent them from moving towards each other; two inner, opposite sides of the rectangularly cross sectioned valve-body holding the separator roller in position with respect to the retainer belt, the other two sides being in contact with the ends of the assembly of movable elements. Admission of fluid into an end of the valve body causes the assembly to move and thus expose a port in the valve body. Accumulators, pressure relief valves and fluid flow control valves are among the useful applications.

Appl. No.:

5/872218

Inventors:

Earl W. Traut - Orlando FL

International Classification:

F16C 1926

US Classification:

308200

Abstract:

Radial load ball bearings in which the elements are in rolling contact only, the load bearing balls being separated by smaller spacing balls which are held in position by a spring-disk. Spring-disk pressure holds the load bearing balls against both races during broad temperature changes and accommodates manufacturing tolerances in the size of the balls.

Appl. No.:

5/628350

Inventors:

Earl W. Traut - Orlando FL

International Classification:

F16C 1920
F16C 1940
F16C 1956

US Classification:

308206

Abstract:

Radial load rolling-contact-only bearings wherein rotating rings act as springs and additionally assure continuous separation between all rotating elements, thereby carrying the entire bearing load and permitting radial deflection under load. In other embodiments radial deflection is minimal, most of the bearing load being carried by rollers, the spring-rings serving primarily to maintain separation therebetween. Cumulative-tolerance slippage is avoided or minimal.

Appl. No.:

5/635781

Inventors:

Earl W. Traut - Orlando FL

International Classification:

F16C 1920

US Classification:

308200

Abstract:

Radial and axial bearing devices in which loads are transmitted from a race through a series of circularly disposed rotating elements, and thence through a second series of rotating elements to a second race; the second series of rotating elements being generally roller-shaped and including ends which roll on retainer rings, the retainer rings being fastened to the first race.
