| 20120079906 | VEHICLE TRANSMISSION GEAR LOCKING MECHANISM - A vehicle transmission comprises a locking mechanism selectively preventing an at least one shift drum disposed on a shift drum shaft from rotating. The locking mechanism is movable between a first position and a second position. When in the first position, the locking mechanism prevents the at least one shift drum from rotating in the first direction to engage a first locked position. When in the second position, the locking mechanism prevents the at least one shift drum from rotating in the second direction to engage a second locked position. The second locked position is sequentially before the first locked position in the first direction. | 04-05-2012 |
| 20110260468 | ENGINE ELECTRICAL GENERATOR COOLING DEVICE AND METHOD - A rotor for an electrical generator is disclosed, including a rotor body having a circular portion and a cylindrical portion coaxial with the circular portion. A generally cylindrical recess is defined by the cylindrical portion and the first side of the circular portion for receiving a stator. At least one first wall is at least partially spaced apart from the first side of the circular portion, defining at least one chamber therebetween. The chamber has an inlet. An aperture in the at least one first wall defines an outlet of the at least one chamber. At least one second wall extends outwardly from the first side of the circular portion. The at least one second wall has an end portion adjacent to the inlet of the at least one chamber. An internal combustion engine with an electrical generator and a method of cooling an electrical generator are also disclosed. | 10-27-2011 |
| 20110162613 | INTERNAL COMBUSTION ENGINE OIL TANK ARRANGEMENT - An internal combustion engine has a crankcase, a crankshaft, a cylinder block, and cylinder head assembly. The cylinder block has at least one cylinder. At least one piston is disposed in the at least one cylinder. The at least one piston is operatively connected to the crankshaft. An oil tank enclosure is connected to at least one of the crankcase outer wall and the cylinder block outer wall. The oil tank enclosure and the at least one of the crankcase outer wall and the cylinder block outer wall together form an oil tank. The arrangement of the oil inlet, oil outlet, and blow-by gas outlet in an oil tank; an oil tank having an angled portion for separating blow-by gases from oil; and an arrangement of a blow-by gas passage connected to an oil tank are also described. | 07-07-2011 |

| 20100181515 | AIR SPRING WITH CAP - A poppet valve has a valve head and a valve stem. A piston is capable of reciprocating motion relative to a housing along a reciprocation axis. The piston has a valve-receiving portion for receiving therein an end portion of the valve stem. A cotter secures the valve stem to the piston. A cap is disposed around the valve-receiving portion. A cap lateral portion extends away from the cap end portion in the direction of the valve head. The valve-receiving portion is held between the cap end portion and the cap lateral portion in a direction parallel to the reciprocation axis. At least part of the cap lateral portion is angled toward the reciprocation axis. The part of the cap lateral portion is closer to the reciprocation axis than at least part of the valve-receiving portion. A method of assembling a valve assembly is also described. | 07-22-2010 |
| 20100180842 | INTERNAL COMBUSTION ENGINE AIR SPRING SYSTEM ARRANGEMENT - An internal combustion engine has at least one intake valve and at least one exhaust valve. A first spring biases the at least one intake valve to a closed position. A second spring biases the at least one exhaust valve to a closed position. At least one of the first and second springs is an air spring. An air compressor is disposed inside the cylinder head and fluidly communicates with the air spring to supply air to the air spring. The air compressor being disposed between a crankshaft and a cylinder head cover in a direction parallel to a cylinder axis is also disclosed. | 07-22-2010 |
| 20100180841 | AIR SPRING SYSTEM FOR AN INTERNAL COMBUSTION ENGINE - An internal combustion engine has at least one intake valve and at least one exhaust valve. A first spring biases the at least one intake valve to a closed position. A second spring biases the at least one exhaust valve to a closed position. At least one of the first and second springs is an air spring. An air compressor fluidly communicates with the air spring to supply air to the air spring. The air compressor is operatively connected to a rotating shaft of the engine to be selectively driven thereby. A motor is operatively connected to the air compressor to selectively drive the air compressor. A method of supplying air to the air spring of the above engine is also disclosed. A method of supplying air to an air spring of an engine having both a mechanical and an electrical air compressor is also disclosed. | 07-22-2010 |
