Abstract: A lubricated cylinder wall in which an oil permeable cylinder ring is located on the inside surface of a cylinder. Oil from an oil supply channel located behind the oil permeable ring supplies the ring with oil. When the oil pressure in the oil supply channel is greater than the pressure inside the cylinder, oil is forced through the oil permeable ring and onto the inside surface of the oil permeable ring. Because the ring is located in the cylinder wall at a location above the bottom dead center location of the piston, upward motion of the piston inside the cylinder sweeps oil from the inside surface at the oil ring over the inside surface of the cylinder. The oil ring is installed in the cylinder by coiling it to a smaller diameter then the cylinder, placing the coiled ring in a groove on the inside surface of the cylinder, pressure fitting the coiled ring into the groove, and then honing the inside surface of the ring to be flush with the inside surface of the cylinder.

Abstract: The internal combustion engine performs the thermodynamic cycle partially inside the cylinder, with the piston connected to the crankshaft, and partially in a turbo blower in which there takes place the final stage of the expansion of the burnt gases and, simultaneously, the suction and the first phase of compression of the air. The said compression is completed afterwards in the cylinder, continuously and without any partialization.

Abstract: The present invention provides an improved cooling system for a reciprocating piston engine. The engine is of the type having at least one cylinder and a piston movable between a top dead and bottom dead center. The cooling system comprises a housing or coolant jacket which encircles the outer end of the cylinder and extends towards the inner end of the cylinder. The coolant jacket, however, terminates short of the inner end of the piston when the piston is at its top dead position. A fluid passageway is formed through the housing and has both an inlet and outlet. Liquid coolant is supplied under pressure to the inlet port on the housing. The coolant flows through the lower section of the water jacket surrounding the piston area thus achieving uniform adequate cooling of both the combustion chamber and piston. In addition, an oil nozzle mounted within the engine crankcase directs a jet of oil onto the inner surface of the piston dome for further cooling of piston and subsequently supplements cooling of the cylinder barrel and head. The oil jet is the primary cooling mechanism for the section of the barrel not enclosed by the water jacket.

Abstract: A two-piece piston assembly comprises an upper portion or a ring carrier part that may be made of malleable iron, cast iron, or a similar iron, and a lower portion or cross-head part, referred to as a skirt, that may be made of aluminum or an alloy thereof. The assembly is configured to increase the contact of cooling liquid with the underside of the crown and eliminate problems accompanying undue heating in this area of the piston. The cocktail-shaker action of the two-piece piston assembly is employed to enhance the cooling effect. A separate cup-like device is secured around the outside of the lower end of the crown member of the piston and is thus positioned between the upper and lower portions of the piston to retain the oil and effectively deliver it to the underside of the crown.

Abstract: A tractor transmission is provided with a clutch housing containing an oil reservoir vented to the main transmission which is vented to atmosphere. A transfer pump is disposed in the clutch housing to pump an oil-air mixture from the reservoir to the main transmission housing. A portion of the pumped oil-air mixture is diverted through a line of a predetermined size to lubricate the front differential. When the oil reaches the front differential, it is diverted to the left and right final drive gear spaces separated by left and right walls from the differential gears. The oil in the final drive spaces increases in height until it passes through either the bearings supporting the differential housing or through the center of the differential pinion gears to the differential gear spaced. Holes in the left and right walls provide maximum levels of oil in the final drive spaces. When the oil spills over into the differential gear space, it lubricates the differential gears and then passes into a baffle and an overflow line which is located below the center line of the differential. The baffles separate the oil from the air and the pressure of the air in the sealed differential forces the oil through the overflow line back to the reservoir in the clutch housing.
