    摘要: A lubricating apparatus for small-sized four-cycle engines to be used in portable type bush cutters, knapsack type powered sprayers, etc. In the lubricating apparatus, an oil returning channel is arranged to provide communication between a valve gear room and an oil sump, and an oil inhaling channel is branched from the middle of the oil returning channel so as to provide communication to an opening in an immediate lower portion of a skirt of a piston being at the top dead center. By this means, when a crank room is negatively pressurized, the oil sucked from the valve gear room is taken through the oil inhaling channel being in communication to a point inside a cylinder where the highest negative pressure is generated, and fed into the cylinder. An opening portion of the oil returning channel is provided with a check valve for opening when the engine is upright and closing when the engine inverted or slanted to prevent the backflow of oil from the oil sump to the oil returning channel. In order to carry out the returning of oil to the oil sump securely, the valve gear room further comprises an oil inhaling means being capable of immersing its extremity into the oil collected inside the valve gear room when the engine is put over sideways.

    摘要: In an engine-driven handheld vacuum/blower, a first grip is provided as one part of an outer shape of an engine casing in which an engine is mounted, and a second grip is formed on a fuel tank which forms another part of the outer shape of the engine casing. The first grip and the second grip are positioned on the opposite sides of the center axis of the engine. Therefore, since there is no unbalanced load applied on either of both the hands, an operator can easily maintain the posture during operation, and can work with the vacuum/blower under good efficiency.

    摘要: A cam gear is mounted on a camshaft, and an intake cam and an exhaust cam are formed on the cam gear for operating an intake valve and an exhaust valve of a hand starting four-cycle engine. A decompression device is rotatably mounted in the cam gear. A decompression cam of the decompression device is exposed from the exhaust cam. The decompression device has a weight, and a spring is provided for urging the weight to the cam shaft. Elastic force of the spring is set so that the weight is urged toward the camshaft in hand starting operation of the engine and moved apart from the camshaft by centrifugal force, thereby projecting the decompression cam in the compression stroke of the engine as to open the corresponding valve.
