US Patent:

6422346, Jul 23, 2002

Filed:

Dec 3, 1999

Appl. No.:

09/455007

Inventors:

Kenneth T. Gilbert - Bluff City TN

Assignee:

Bristol Compressors, Inc - Bristol VA

International Classification:

F01M 100

US Classification:

184 616, 184 31, 418 64

Abstract:

In a gas compressor having a crankcase rotatably supporting a drive shaft connected to and adapted for operating compression generating structure of the compressor, the shaft being connected to an electrical motor for being driven thereby in either rotational direction, and the shaft having an oil passage formed generally longitudinally therein for conveying lubricating oil to various portions of the compressor, unique oil pump structure having from one to about six slots formed generally radially thru a portion of the shaft and communicating with the oil passage, an elongated vane slidably mounted in each slot for movement both longitudinally and laterally thereof to provide an oil conduit alongside each of the vanes regardless of the direction of rotation of the shaft, a wall slidably enclosing the shaft portion and having a circular inner surface eccentrically positioned with respect to the shaft portion such that a small vertical segment of the inner surface lies adjacent the shaft portion to thereby provide a generally crescent shaped pumping chamber between the shaft and the inner surface, and an oil inlet provided thru the wall and communicating with the pumping chamber and adapted to communicate with oil in the compressor oil sump.

A01D 69/10

Abstract:

A brake apparatus for restricting rotation of a rotatable member of a mowing machine, thereby controlling rotation of a wheel of the mowing machine, includes a brake member fixable on the rotatable member, and a gripping member for engaging and disengaging the brake member for restricting or permitting rotation of the rotatable member. A thrust link is coupled to the gripping member such that movement of the thrust link causes the gripping member to engage or disengage a radially outer surface of the brake member. For example, the gripping member may be biasedly engaged with at least a partial circumferential extent of the brake member such that actuation of the thrust link causes disengagement of the gripping member from the brake member.

International Classification:

F01C 1/34
F01C 21/10
F01C 21/08

Abstract:

A hydraulic motor includes a rotor and a stator, wherein the rotor and the stator define a plurality of motor pockets for receiving a flow of hydraulic fluid, and the rotor rotates relative to the stator based on a pressure differential between the motor pockets. A commutator having porting controls the flow of hydraulic fluid into the motor pockets. The rotor rotates about a first axis and the stator orbits about a second axis, and the stator is configured to orbit such that the second axis orbits about the first axis. The commutator is eccentrically piloted about the first axis and the second axis so that the commutator both rotates and orbits to control the flow of hydraulic fluid into the motor pockets. With such configuration, an output shaft is driven by rotation of the rotor about the first axis without orbiting, obviating the need for a drive link.

International Classification:

F01C 1/10
F01C 21/10

US Classification:

418 1, 418 613

Abstract:

A hydraulic geroller (gerotor) motor, wherein an inner rotor of a revolving group has a plurality of lobes circumferentially spaced along an outer periphery of the inner rotor, and an orbiter of the revolving group includes an orbiting ring and rounded vane portions preferably formed by roller vanes contained in inner recesses of the orbiting ring for common orbiting with the orbiting ring about the fixed longitudinal axis. The orbiter also has fixed for orbiting therewith, fluid windows for directing fluid from the fluid ports to the revolving group. The windows may be formed in an integral portion of the orbiter or in a valve plate mounted for common orbiting with the orbiting orbiter. The valve plate cooperates with a stationary commutator plate or assembly to provide an efficient arrangement for the delivery and exhaust of hydraulic pressure fluid to and from the hydraulic motor.
