Patent

CA 2368207

A four-stroke internal combustion engine (20) is provided. There is provided within an engine housing (28) an oil reservoir (126) and a valve chamber (156) which independently communicate with a crank chamber (124). 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 with 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).

l'invention concerne un moteur (20) à combustion interne à quatre temps. Ce moteur comprend un bloc moteur (28) un carter d'huile (126) et un logement de soupapes (156) qui communique de façon indépendante avec un carter du moteur (124). Une chicane (116 ) stratégiquement placée et un passage, situés dans le corps de moteur (28), canalisent de façon appropriée l'huile de graissage dans le corps de moteur (28) de sorte que la cavité intérieure du moteur est lubrifiée dans diverses positions, et de sorte qu'elle s'écoule et soit retenue dans les chambres du corps du moteur appropriées pendant l'arrêt. L'invention concerne aussi un reniflard pour moteur (20) à combustion interne qui comprend un arbre à cames (98) possédant un passage creux en liaison avec le carter du moteur (124) et avec le système d'admission du moteur. L'invention concerne encore un bloc moteur qui peut être utilisé pour des moteurs de puissances différentes. Enfin, l'invention concerne un ensemble palier de vilebrequin (68, 70) qui ne risque pas d'être endommagé lors de l'insertion du vilebrequin (80) dans le carter du moteur.
