Abstract: A constant level oiler is provided which is ventilated in such a manner so as to eliminate the need for a large surge chamber. Such an oiler has an advantage in that the problems associated with the fluid surge resulting when the lubricated machine is shut down are eliminated. Furthermore, since a large surge chamber is unnecessary in the present device, the attendant costs associated therewith are also eliminated.

Abstract: A top cover for oilers having an aperture centrally located about a disc-shaped body through which a lubricating fluid may be dispensed into the reservoir of the oiler is provided. Such a cover has an advantage in that a larger filling aperture is thus attained thereby providing for more efficient filling of the oiler reservoir and is further attained at no cost as a by-product of other necessary machining.

Abstract: A timing gear assembly for a trochoidal rotary device comprises a dual set of like timing gear systems provided on opposite lateral sides of the rotor to prevent rotor wobble. The pair of timing gear systems are in balance and equally loaded in support of the rotor at all times during rotor movement; and the opposed timing gear systems are circumferentially offset relative to one another, either by virtue of relative circumferential displacement of the pinion gears or ring gears or both.

Abstract: An improved rotary device having means facilitating an increased power shaft diameter. This means includes a pair of gear elements which are not related to the eccentricity of the device or to each other in the conventional manner known in the prior art. To compensate for these discrepancies in such relationships, additional gear rotational means is needed to control the rotation and revolution of the altered gear structure to compensate for the failure to maintain the heretofore required relationships with the eccentricity and with each other. One embodiment of the invention utilizes a plurality of movement control discs to accomplish this gear compensating motion, while a second embodiment utilizes a plurality of compensating gears.

Abstract: A rotary expansion power unit, such as a steam engine, which has a planetating rotor in a housing having an epitrochoidal cavity. In known engines, hot expansion fluid is directed through a hollow interior in the rotor and surrounds the rotor journal bearing. This leads to excessive expansion of the rotor and requires an excessive flow of cooling oil to the bearing. The invention isolates the expansion fluid from the interior of the rotor by having a valve disc fastened to the rotor crankshaft with a first seal means between the valve disc and housing end wall and a second seal means between the valve disc and rotor.

Abstract: In an epitrochoidal rotary air compressor, a stationary portion includes a stationary single offset power shaft on which is mounted an epitrochoidal rotor in a rotary housing portion. The rotor includes a pinion gear which cooperates with a ring gear in the rotary housing portion to move the rotor within the rotor chamber in the rotary housing portion. A centrifugally driven lubrication system including lubrication channels extending internally of the stationary power shaft is provided for lubricated bearings and gears within the apparatus. An improved compression seal engaging the lateral faces of the rotor has a plurality of buttons biasing a split ring against the lateral faces of the rotor. An air pressure unloader valve is centrifugally operated to release the load from the compressor during startup. A rotary after-cooler in the rotary housing portion removes thermal energy from the compressed air prior to leaving the compressor and an inter-cooler may be provided in a two stage compressor.

Abstract: A device and method for milling a trochoidal rotor having a predetermined trochoidal configuration. The trochoidal rotor is used in a trochoidal rotary device in which working chambers are defined between the rotor and a housing. The rotor device has inlet and outlet ports for passing a fluid or gas. The rotor is made by first planetating a rotor blank having a predetermined width and having an edge region about a predetermined axis. The cutting blade is provided which has a predetermined geometry and which is located at a predetermined fixed distance from the axis. The cutting blade is engaged with at least a portion of the edge region of the rotor blank. The cutting blade traverses the edge region of the rotor blank to cut the edge region into a predetermined trochoidal configuration. When the cutting blade is a helical flute, the engagement of the cutting blade with a portion of the edge region results in cutting at a predetermined location within the portion of the edge region. This cutting location continuously sweeps back and forth in an axial direction across the portion of the edge region as a rotor blank rotates.
