    • A cartridge heater is accommodated in a heater bore in a shaft connected to a valve element, and a heating portion provided at an end portion of the cartridge heater is located at a joint portion of the shaft and the valve element. At the joint portion, a heat receiving groove and a pressurizing portion communicating with the heater bore are provided at a position between a surface of the valve element and that of the shaft located so as to oppose and to contact each other. The heat receiving groove includes an arcuate groove portion of the same radius as that of the heating portion of the cartridge heater, and the heating portion is pressed by the pressurizing portion to enter into plane-to-plane contact with an inner circumferential surface of the arcuate groove portion of the heat receiving groove, upon fastening the valve element and the shaft to each other with a bolt, with the heating portion located between the heat receiving groove and the pressurizing portion.

    • Roller insertion grooves are formed along the longitudinal direction of inner wall portions of side frames, which are provided in the interior of a housing that makes up a gate valve. Respective pairs of retaining rollers are inserted into the roller insertion grooves. A valve disk is tilted, such that in a valve closed state in which the valve disk is seated on a valve seat, a load imposed from a displacement block, which is connected to a valve rod and tiltably displaced thereby, is imposed on the retaining rollers, the load being borne by first and second pressure receiving bodies, which abut against the retaining rollers and are disposed on the side frames. The first and second pressure receiving bodies are formed from a material having a hardness greater than that of the side frames.
    • 沿着构成闸阀的壳体的内部设置的侧框架的内壁部的纵向方向形成有滚子插入槽。 各对保持辊插入到辊插入槽中。 阀盘倾斜,使得在阀盘安置在阀座上的阀关闭状态下,从连接到阀杆并由此可倾斜地偏移的位移块施加的负载施加在保持 滚子,负载由第一和第二压力接收体承载,其抵靠保持辊并且设置在侧框架上。 第一和第二压力接收体由具有大于侧框架的硬度的材料形成。

    • Disclosed is a small rotary cylinder device wherein friction loss is reduced and energy is conserved by reducing effects of a reaction force applied from cylinders to pistons, which is incorporated in a piston composite body and which linearly reciprocates, the piston composite body being eccentrically connected to a first crank shaft rotating about a shaft. Guide bearings (1c) guide linear reciprocation of first and second piston assemblies (7, 8) attached to second tube bodies (6b), which are caused by rotating a first crank shaft (5) about a shaft (4) and rotating a piston composite body (P) about the first crank shaft (5), in the radial direction of a rolling circle of second imaginary crank shafts (14a, 14b), which has a radius 2r and which is centered at the shaft (4).
    • 公开了一种小型旋转气缸装置,其中减少了摩擦损失并且通过减小从气缸施加到活塞的反作用力的作用来节省能量,所述反作用力被结合到活塞复合体中并且直线往复运动,所述活塞复合体偏心地连接到 围绕轴旋转的第一曲柄轴。 引导轴承(1c)引导通过使第一曲柄轴(5)围绕轴(4)旋转并旋转活塞而引起的附接到第二管体(6b)的第一和第二活塞组件(7,8)的线性往复运动 复合体(P)围绕第一曲柄轴(5)沿第二假想曲轴(14a,14b)的滚动圆的径向方向延伸,其具有半径为2r且以轴(4)为中心。
