    • PURPOSE:To enable mass-production by making a conduction hole for applying the compressed fluid onto the bottom of a vane constructed on the slide face of a swing blade, thereby utilizing the compressed fluid against pressurization onto the bottom of the vane and eliminating a spring. CONSTITUTION:A compression fluid inlet/outlet port 23 is made in the surface at high pressure side of a swing blade 10 and a conduction hole 24 to the bottom of vane 21 is provided not to extend to the opposite surface of the high compression side. Consequently the fluid compressed by the swing blade 10 will pressurize the bottom of vane 21 through said port 23 and hole 24. Since the pressurizing force will vary with correspondence to the pressure of the compressed fluid, high grade sealing is achieved under high compression process. With such structure a spring for energizing a vane 20 provided on the swing blade 10 is not required resulting in the improvement of performance and mass- production.
    • 目的:为了通过制造用于将压缩流体施加到构成在摆动叶片的滑动面上的叶片的底部上的传导孔来实现批量生产,从而利用压缩流体抵抗叶片的底部加压并消除弹簧 。 构成:在摆动叶片10的高压侧的表面形成有压缩流体入口/出口23,并且设置到叶片21的底部的通气孔24不延伸到高压缩侧的相对表面。 因此,由摆动叶片10压缩的流体将通过所述端口23和孔24对叶片21的底部加压。由于加压力将根据压缩流体的压力而变化,因此在高压缩过程中可实现高等级的密封。 通过这种结构,不需要用于对设置在摆动叶片10上的叶片20进行通电的弹簧,从而提高性能和批量生产。

    • PROBLEM TO BE SOLVED: To provide a driven unit of fluid machine to make suction and exhaust efficiently embodied in a small, light and simple construction. SOLUTION: The setting of the internal circumferential surface L of a casing is made by drawing the rotational circle K of a piston pin centering on the point O and drawing the reference line APC of a piston, wherein the length of the segments AP and PC is equal to the radius of the circle K and the points A and C become the reference point of the piston. Then any arbitrary curve ABC passing the points A and C is drawn, and the point A of the straight line APC as reference line of the piston is moved along the curve ABC to the point C. At the same time, the point P moves along the circle K to P1 and P2, and the point C follows a locus of a curve CDA. The shape of this internal circumferential surface decides the change of the inertial force due to rotation of the piston revolving while it makes rotation in reversals internally. In this driven unit of fluid machine, setting of the reference curve is made so that the ratio of H to G lies within the range H/G=0.12-0.19, where H is the distance from the point B of the reference curve ABCDA to the point P while G is the diameter of the circle K.
