摘要： A scroll compressor including a stationary scroll formed with a scroll wrap, an orbiting scroll formed with a scroll wrap, a rotating shaft for putting the orbiting scroll into an orbiting motion, a rotating bearing for rotatably supporting the rotating shaft on the stationary scroll, an orbiting scroll bearing provided at an eccentric shaft portion of the rotating shaft and operative to orbitably support a central portion of the orbiting scroll. A coupling transmits a torque of a driving shaft to the rotating shaft. The scroll compressor is compact based on the layout of a balancer. The orbiting scroll bearing is disposed at a central portion of the rotating shaft, and the coupling is provided with the balancer. The stationary scroll may be provided with ribs being formed therein with an oil passage for connection between a central oil passage formed in the rotating shaft and the exterior.

摘要： A supercharger lubricating structure for an internal combustion engine is provided that can supply oil to a supercharger through a short oil passage without use of external piping and downsize a lubricating oil pump. A supercharger lubricating structure for an internal combustion engine can be characterized by the following: A rotating shaft can be connected to a crankshaft via a joint. A connection pipe can be insertably passed through the crankshaft and the rotating shaft to allow an intra-crankshaft oil-feed passage and an intra-rotating-shaft oil-feed passage to communicate with each other. An eccentric shaft portion can be provided on the rotating shaft. A supercharger composed of an orbiting movable scroll and front and rear fixed scrolls can be provided on the eccentric shaft portion via needle bearings. The front and rear fixed scrolls can be provided with ball bearings and the needle bearing supporting the rotating shaft. Oil passages can be disposed to allow the intra-rotating-shaft oil-feed passage, the ball bearing, the needle bearing and the needle bearings to communicate with one another.

摘要： A crankshaft mechanism for an engine wherein a crankshaft can be disposed close to the piston side while securing a moment of inertia. In the crankshaft mechanism for the engine including the piston, the crankshaft is provided with a crank pin and counterweight parts, and a connecting rod connecting the piston and the crank pin of the crankshaft to each other, the inner side of a circumferential end, on the opposite side of the crank pin, of each of the counterweight parts is cut out along a curve at equidistance R from the center Q of the crank pin, to obtain such a shape so as to avoid a projected part, projected in the direction of the piston, at the lower end of a small end part of the connecting rod when the piston reaches the bottom dead center.
