摘要： Corner seal sockets (26) are formed at the end of apex seal slots (58) formed in a rotor (10). A twisted split washer spring (70) is positioned in each socket (26) between the base wall (28) of the socket (26) and the inner end of the corner seal (16). The springs (70) bias the outer end surfaces of the corner seals (16) against the inner side surfaces of the housing sidewalls (20, 22). A radial apex seal slot (32) is formed in each corner seal (16). The base (38) of each slot (32) is substantially semi cylindrical in shape. It and the cylindrical peripheral surface (44) of the corner seal (16) form an arch shaped bight that connects side portions of the corner seals (16) together. End portions of the apex seals (18) extend into the apex seal slots (32) in the corner seals (16). The end portions of the apex seal biasing spring (60) contacts spring abutments (52, 54) which project radially inwardly from the outer ends of the apex seal (18). The corner seal may have a recessed outer face surrounded by a radially narrow seal surface.

摘要： A rotary Wankel type engine system is disclosed, wherein the crankshaft is supported by a center main roller bearing. The rotor apexes are sealed by two piece apex seals and by side seals. The engine system further includes an oiling system which permits oil flow through the center bearing and through lubrication passages in the engine rotor to provide a means for cooling the engine rotor under high loading conditions. Riblets are defined in the combustion face of the rotor to promote aerodynamic lateral stratified charge control to minimize atomized fuel charge loss to surface wetting before ignition.

摘要： In the preferred embodiment, the invention comprises a sealing arrangement in which an elongated slat-type seal is provided for slidable engagement within the slot of a rotor (such as a Wankel engine-type rotor, or the rotor in a vane-type compressor) and includes a leaf spring for biasing the seal outwardly from the slot to effect fluid sealing externally of the rotor. The leaf spring and seal have special, mutually-engaging keying configurations, and the spring has particularly determined contact points which maintain all possible biasing force therein for the longest service time thereof.

摘要： A seal mechanism for the periphery of the rotor of a rotary piston engine including a sealing ledge supported on the rotor to be pivotable about an axis extending in the longitudinal directional thereof and operative to make sealing contact with an opposed surface of said rotary piston engine over a limited region of the periphery of the sealing ledge facing toward said opposed surface. Through at least one secondary member extending parallel to the sealing ledge at a point of its periphery between the sealing ledge and the rotor, a surface region is defined on the sealing ledge at which forces are developed by the fluid working medium of the engine to effect a desired sealing engagement between the sealing ledge and the opposed surface of the engine.

摘要： A corner seal member for use in a rotary internal combustion engine is constructed with an apex seal groove and an elongated cavity. The elongated cavity forms a thin wall having a substantially semicircular cross-section in the opposite side of the apex seal groove. The gas pressure delivered into the elongated cavity is advantageously used for urging the corner seal towards the inner surface of the corner seal groove, thereby preventing the gas pressure from leaking into an adjacent working chamber.

摘要： A base metal, such as the aluminum or iron housing of a conventional rotary or reciprocating-piston internal combustion engine, and a sealing member applicable to the pistons or rotor thereof are coated with a layer of a wear-resistant alloy, such as molybdenum-ruthenium or tungsten-ruthenium alloy, either by evaporating the elements of the alloy by electron guns onto the surfaces to be coated or by vaporizing a wire of the same alloy in a vacuum chamber by the application of a high-tension electrical discharge through the wire from an electrical condenser bank. Depositing the alloy is done on a production basis by passing workpiece holders in a circular path through a vacuum chamber beneath the electron gun, followed by a realloying step through a laser beam, an acid dip, a rinsing dip, a drying by heat, and a final honing.
