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.
摘要翻译：用于便携式衬套切割机，背包式动力喷雾机等的小型四冲程发动机的润滑装置。在润滑装置中，设置回油通道，以在阀齿轮室和油底壳之间提供连通并且吸油通道从回油通道的中间分支，以便与位于上止点的活塞的裙部的直接下部的开口相连通。通过这种方式，当曲轴室被负压时，从阀门齿轮室吸入的油被吸入通过与产生最高负压的气缸内的点连通的吸油通道，并被供给到气缸中。回油通道的开口部分设置有止回阀，当发动机反转或倾斜时发动机垂直和关闭时打开，以防止油从油底壳向回油通道回流。为了进行将油返回到油底壳的可靠性，阀齿轮室还包括一个吸油装置，当发动机横向放置时，该吸油装置能将其末端浸入收集在阀齿轮室内的油中。

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.
摘要翻译：在发动机驱动的手持真空/鼓风机中，第一把手被设置为发动机壳体的外形的一部分，其中安装有发动机，并且第二把手形成在形成外部的另一部分的燃料箱发动机外壳的形状。第一把手和第二把手位于发动机的中心轴线的相对侧上。因此，由于在两只手中都没有施加不平衡载荷，所以操作者在操作中可以容易地维持姿势，并且能够以高效率与真空/鼓风机一起工作。

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.
摘要翻译：凸轮齿轮安装在凸轮轴上，并且进气凸轮和排气凸轮形成在用于操作起动四冲程发动机的进气门和排气门的凸轮齿轮上。减压装置可旋转地安装在凸轮齿轮中。减压装置的减压凸轮从排气凸轮露出。减压装置具有重量，并且设置有用于将重物推压到凸轮轴的弹簧。弹簧的弹性力被设定为使得重量在发动机的手动启动操作中被推向凸轮轴并通过离心力从凸轮轴移开，从而将减压凸轮在发动机的压缩冲程中突出以打开相应的阀。
