A lubricating apparatus of the present invention is applied to a transmission having a plurality of rotating shafts, and includes a first rotating shaft having a first oil passage, a second rotating shaft, and an impeller fixed to an axial end of the first rotating shaft. The impeller is arranged in a first oil storage chamber communicated with an outlet of the first oil passage. The impeller rotates with the first rotating shaft to scatter oil, and supplies the oil to the second rotating shaft.

Lubricating apparatus for rotating shaft

A lubricating apparatus includes a rotating shaft disposed horizontally; a supporting wall supporting the rotating shaft with a bearing; an oil chamber surrounded by the supporting wall and the rotating shaft; an oil passage extending within the rotating shaft and communicating with lubricating portions; an oil intake portion for receiving and supplying the oil to the oil chamber; and a plurality of guide ribs formed in the supporting wall. The guide ribs are adapted to form at least two oil flow paths from a radially-outer portion of the oil chamber toward a center portion of the chamber.

A power transmission mechanism having a dog clutch for freely connecting and disconnecting power transmission between a first rotor and a second rotor on a common rotational shaft. The dog clutch has a plurality of dog jaws in one of the rotors and has, in the other rotor, a plurality of recess portions or other dog jaws to which the former dog jaws can be engaged. Tapered surfaces are formed at an end face of each of the former dog jaws in the axial direction and each of wall surface portions formed between the recess portions or an end face of each of the latter dog jaws.

Power transmission mechanism

A muffler cooling device for a V-type engine which includes an engine cooling fan disposed at an end of a crankshaft. An air guide plate is provided at a part of a duct through which air sucked by the cooling fan flows, and the duct has at least one opening through which the air flows as being guided by the air guide plate. The arrangement is such that the air having flown through the opening is led, through a space surrounded by a V-bank formed by cylinder heads and an intake manifold, to an area in which a muffler and exhaust pipes extending from the cylinder heads to the muffler are arranged.

An oil relief valve for lubrication systems for internal combustion engines comprising a valve body having a hollow cylindrical shape, a valve seat provided at a bottom end of the valve body, a valve plug placed in the seat, a port bored in the seat to bring the oil relief valve into fluid communication with a lubrication line which supplies oil from an oil pump to various engine parts to be lubricated, a spring mounted on top of the valve plug and adapted to urge the plug against the seat to close the port, and slits cut in the valve body and provided to bring the valve in fluid communication with an oil pan. The spring has a free length smaller than the distance of the space defined between the valve plug and the top end of the valve body.

A two-cylinder engine comprises a first cylinder and a second cylinder adapted to perform explosions at such timing that an interval from explosion in the first cylinder to explosion in the second cylinder becomes shorter than an interval from the explosion in the second cylinder to the explosion in the first cylinder, a single carburetor, and an intake manifold having an intake passage communicating with the carburetor and first and second branch passages branched from the intake passage and communicating with the respective cylinders. The intake passage and the branch passages are arranged such that an angle formed between an axis of the intake passage and an axis of the first branch passage becomes smaller than an angle formed between the axis of the intake passage and an axis of the second branch passage.
