    • An engine valve device, wherein an opening part (7) smaller in area than the end surface of a piston (5) is provided in the end surface of a cylinder (3) to form a valve seat (8), and a valve disc (9) in contact with the valve seat (8) is disposed on the outerside of the valve seat (8) so that the cylinder (3) can be moved away from and toward the valve disc (9) and, in a compression stroke when the piston (5) rises, the valve seat (8) is in press-contact with the fixed valve disc (9) because upward force is applied to the upper end surface of the cylinder (3) and the cylinder (3) is urged toward the valve disc, and the area of the opening part is increasable up to the ultimate diameter of the piston, providing a highly airtight, simple-structured valve device yielding high engine energy efficiency.
    • 一种发动机气门装置,其特征在于,在气缸(3)的端面设置有比活塞(5)的端面小的面积的开口部(7),形成阀座(8) 与阀座(8)接触的阀(9)设置在阀座(8)的外侧,使得气缸(3)能够离开和朝向阀盘(9)移动,并且在压缩冲程 当活塞(5)上升时,阀座(8)与固定阀盘(9)压接,因为向上的力施加到气缸(3)的上端面,气缸(3)是 被推向阀盘,并且开口部分的面积可以增加直到活塞的极限直径,从而提供高度气密,简单结构的阀装置,其产生高发动机能量效率。

    • An internal-combustion type iron has a nozzle provided in a grip portion so as to spray a jet of gas supplied from a liquified-gas tank into a hollow barrel. The hollow barrel has a base portion fitted to the grip portion and communicating with the nozzle. An air hole is provided in the base portion of the barrel so that the outside air may be sucked into and be mixed with the gas from the nozzle. A gas flow control body is disposed in the center of a hollow portion of the barrel generates a stagnant vortex flow in the flow of the mixture of the gas and air. A mixing chamber is provided in the hollow portion of the barrel between the air hole and the gas flow control body. The mixing chamber has a length sufficient for the required mixing of the gas with air and for stabilization of flow velocity. A heating chamber is provided in the hollow portion of the barrel between the gas flow control body and an exhaust port provided at the tip of the barrel. The heating chamber has a length sufficient for the required heating of the barrel by the combustion gas. The stagnant vortex flow of the gas mixture is generated at a predetermined distance from the nozzle by the gas flow control body and is ignited with the flame being maintained at this point.
    • 内燃式熨斗具有设置在把手部分中的喷嘴,以将从液化气罐供应的气体喷射到中空筒中。 中空筒体具有嵌合于把持部并与喷嘴连通的基部。 在筒的基部设置有空气孔,使得外部空气可以被吸入并与来自喷嘴的气体混合。 气体流量控制体设置在桶的中空部分的中心,在气体和空气的混合物的流动中产生停滞的涡流。 在气孔和气流控制体之间的筒的中空部分中设置有混合室。 混合室的长度足以使气体与空气混合,并稳定流速。 在气体流量控制体和设置在筒的尖端处的排气口之间的筒体的中空部分中设置有加热室。 加热室的长度足以通过燃烧气体对筒的所需加热。 气体混合物的停滞的涡流在气体流量控制体距离喷嘴预定距离处产生,并且在该点保持火焰而被点燃。

    • A production unit for twisted cable is disclosed that facilitates the supply and removal of fixed length cables, thereby contributing to improved workability and automation compatibility. A plurality of pairs of relatively rotatable opposed cable clamps are provided with one cable clamp of each pair provided at one end of the fixed length cables and the other of each pair of cable clamps provided at the other end. Each pair of clamps is intermittently moved forward in a direction transverse to the opposed direction in which the cables extend. Each pair of cable clamps sequentially circulate, and the supply and removal operation of fixed length cables to and from the pairs of clamps are conducted respectively at predetermined positions by stations provided in the circulating route, by which it becomes possible to carry out the supply and removal of fixed length cables to continuously repeat the twisting operation.
    • 公开了用于扭绞电缆的生产单元,其有助于固定长度电缆的供应和移除,从而有助于提高可操作性和自动化兼容性。 多对相对旋转的相对的电缆夹具设置有每对的一个电缆夹,其设置在固定长度电缆的一端,另一端设置在每对电缆夹中。 每对夹具沿横向于电缆延伸的相对方向的方向间歇地向前移动。 每对电缆夹依次循环,并且固定长度的电缆对和从夹子对的供给和移除操作分别在循环路径中设置的站的预定位置进行,由此可以执行供应和 拆除固定长度的电缆,以连续重复加捻操作。
