A strategically placed divider (116) and passageway, located within the engine housing (28), appropriately direct lubricant within the engine housing (28) so that the internal cavity of the engine is lubricated during use in various operating attitudes, and so that the fluid flows to and is held in the proper chambers of the engine housing during storage. There is also provided a breather arrangement for an internal combustion engine (20) which includes a cam shaft (98) having a hollow passageway in communication wit the crank chamber (124) and the air intake system of the engine. There is also provided an engine housing which can be utilized for engines having different horse power ratings. There is also provided a crankshaft bearing assembly (68, 70) which prevents damage to the bearing upon insertion of the crankshaft (80) into the crank chamber (124).

摘要： A breather device for an engine comprises a gas-liquid separation chamber (71) communicating with a crankcase chamber (23) through a one-way valve, a breather passage (84) opening the gas-liquid separation chamber into an air cleaner (4), first (88 1 ) and second (88 2 ) oil suction holes arranged below and above an inner end (82a) of the breather passage opening to the gas-liquid separation chamber, and an oil passage (58) communicating the first and second oil suction holes to an oil reservoir chamber (22) having a pressure lower than that of the gas-liquid separation chamber. This construction enables the oil separated from the blow-by gas and liquefied in the gas-liquid separation chamber to be returned quickly to the oil reservoir chamber through the first or second oil suction holes, irrespective of whether the engine is in an normal upright position or an inverted position.

摘要： L'invention décrit un outil à moteur (20) tenu à la main, conçu pour être porté par un utilisateur pendant son utilisation. L'outil à moteur (20) possède un cadre (22) comprenant une poignée (24, 26) tenue par l'utilisateur, un instrument (32) fixé audit cadre (22) possédant un élément d'entrée rotatif (64), ainsi qu'un petit moteur en aluminium à combustion interne et à quatre temps (30) fixé au chassis, afin d'actionner l'instrument. Un arbre à manivelle (36) est monté en palier sur le bloc moteur, de façon à effectuer une rotation autour d'un axe d'arbre à manivelle. Un piston (38) effectue un mouvement de va-et-vient à l'intérieur de l'alésage (34) et est accouplé à l'arbre à manivelle au moyen d'une tige d'accouplement (40) sur laquelle se trouve un gicleur d'huile (60) servant à introduire, de façon intermittente, l'huile à l'intérieur du réservoir d'huile (58) placé dans une enceinte, de façon à lubrifier le moteur. Le moteur (30) est pourvu d'un ensemble tête de cylindre (42) définissant une chambre de combustion compacte (44) possédant une paire d'orifices d'échappement et d'admission (46, 52) situé dans la partie supérieure coopérant avec les soupapes d'admission et d'échappement (50, 56). L'invention permet de réaliser un moteur léger et de puissance élevée (30) produisant des émissions d'hydrocarbures et de monoxyde de carbone relativement faibles.

摘要： An oil pan structure 1 for the cylinder block 2 of an internal combustion engine for storing lubricating oil in the oil pan. A volume body 4 is submergible at least partly below the oil lever L for displacing a volume of oil when the oil is tilted by displacement to one side in the oil pan as a result of the running condition of the motor vehicle having the engine with the oil pan structure, such as during turning, acceleration, deceleration or banking. The volume body has an inlet opening 7 positioned near an allowable upper limit oil level for a predetermined maximum oil tilting condition for introducing into the volume body the lubricating oil which exceeds the allowable upper limit oil level. The oil pan structure also has an oil discharge passage 9 from the lower portion of the volume body.

摘要： An oil scavenging system for a main shaft bearing (20) in a gas turbine engine (l0) includes a sump (85) adjacent the bearing (20) having a frusto-conical inner surface (2l0) and a constant diameter inner surface (230) contiguous with the frusto-conical surface (2l0). The small diameter end of the frusto-conical surface (2l0) is adjacent the bearing (20) and the latter includes a low efficiency pumping member (l02) which pumps the oil onto the frusto-conical inner surface (2l0) with high tangential velocity. The oil centrifugally adheres to and migrates along the frusto-conical surface (2l0) and has sufficient tangential velocity to also centrifugally adhere to the constant diameter surface (230). The oil adhering to the constant diameter surface (230) drains into a drain entry (232) in the constant diameter surface (230) and is collected by a single scavenge pump pick-up regardless of engine attitude or altitude.
