    • A casing has a circular cylindrical internal surface delimiting an operating chamber. An orbiting piston is mounted so as to orbit about a chamber axis which is the axis of the internal surface. The orbiting piston has a circular cylindrical external surface, a generatrix of the external surface being adjacent to the said internal surface, and a diametrically opposite generatrix spaced form the internal surface. A vane member has a tip face which faces the external surface of the orbiting piston and which has a length substantially equal to that of the orbiting piston. A linkage connects the vane member to the orbiting piston to keep the tip face adjacent the external surface. At least one of the external and internal surfaces has individual compliant strips distributed around the one surface, which run parallel to one another, and project above the one surface.
    • 壳体具有限定操作室的圆柱形内表面。 围绕围绕作为内表面的轴线的腔室轴线轨道运行的旋转活塞被安装。 旋转活塞具有圆柱形外表面,外表面的母线与所述内表面相邻,并且与内表面间隔开的直径相对的母线。 叶片构件具有面向旋转活塞的外表面并且具有与旋转活塞的长度基本相等的长度的尖端面。 连杆将叶片构件连接到旋转活塞,以保持顶端面与外表面相邻。 外表面和内表面中的至少一个具有分布在一个表面上的单独的柔性条带,该条带彼此平行地延伸并突出在一个表面之上。

    • A rotary positive-displacement fluid machine comprising a rotor eccentrically mounted in a casing for rotation about an axis, the rotor having recesses respectively receiving vanes which oscillate in the recesses as the rotor rotates. Each vane is connected by a crank to an arm for oscillation about a vane axis which is located inwards of the outer extremity of the tip which itself has a clearance fit within the casing. The tip of each vane is preferably curved about an axis parallel to the respective vane axis. The machine may be connected to the crankshaft of an internal combustion engine and driven by the pressure difference between the ambient air and that at the engine inlet manifold. Alternatively, the device may be operated as a heat pump.
    • 一种旋转正排量流体机械,包括偏心地安装在壳体中用于围绕轴线旋转的转子,所述转子具有分别接收当转子旋转时在凹部中振荡的叶片的凹部。 每个叶片通过曲柄连接到臂上,用于围绕叶片轴线摆动,该叶片轴线位于尖端的外部末端的内侧,其本身在壳体内具有间隙配合。 每个叶片的尖端优选围绕平行于相应叶片轴线的轴线弯曲。 机器可以连接到内燃机的曲轴并由环境空气与发动机进气歧管处的压力差驱动。 或者,该装置可以作为热泵来操作。
