    • This invention provides a diaphragm pump that decreases the number of components or improves workability in assembling. A crank (4) to which the output shaft (2a) of a motor (2) is pivotally attached has, in its upper surface, a ring-shaped insertion groove (5) with respect to the output shaft (2a) as the center. A projecting driving shaft (9b) is formed integrally with a driver (7). When the lower end (9c) of the driving shaft (9b) is inserted into the insertion groove (5), the axis (9d) tilts. When the crank (4) rotates, an engaging portion provided in the insertion groove (5) engages with the lower end (9c). The driving shaft (9b) rotates while changing the tilt direction of the axis (9d) following the rotation of the crank (4). Hence, when a diaphragm portion (12a) attached to the drive element (7a) of the driver (7) moves upward/downward, a pump chamber (18) expands/contracts so that a pump action is obtained.
    • 本发明提供了一种减少组件数量或提高组装中的可操作性的隔膜泵。 枢轴安装有电动机(2)的输出轴(2a)的曲柄(4)在其上表面具有相对于输出轴(2a)的中心的环形插入槽(5) 。 突出的驱动轴(9b)与驱动器(7)一体地形成。 当驱动轴(9b)的下端(9c)插入到插入槽(5)中时,轴线(9d)倾斜。 当曲柄(4)旋转时,设置在插入槽(5)中的接合部分与下端(9c)接合。 驱动轴(9b)随着曲柄(4)旋转而改变轴线(9d)的倾斜方向而旋转。 因此,当安装在驱动器(7)的驱动元件(7a)上的隔膜部分(12a)向上/向下移动时,泵室(18)膨胀/收缩,从而获得泵动作。

    • A wabble plate type variable displacement compressor comprises a rotation preventing mechanism of the wabble plate which includes (a) an inner ring provided movably in the axial direction although rotation is prevented, supporting a main shaft at the inner diameter portion to rotate relatively and to move relatively in the axial direction and having a plurality of guide grooves for guiding a plurality of balls provided for power transmission, (b) a sleeve functioning as a wabble central member of wabble movement of the wabble plate, provided on the main shaft to rotate relatively thereto and to move in the axial direction and engaging with the inner ring movably in the axial direction, (c) an outer ring having a plurality of guide grooves for guiding balls at positions opposing respective guide grooves in the inner ring, supported on the sleeve wabblingly, supporting the wabble plate fixedly on the outer circumference and supporting a swash plate rotatably via a bearing, and (d) a plurality of balls held by the guide grooves formed in the inner ring and the outer ring and being compressed between the guide grooves to transmit power. While play in a uniform motion joint provided as the wabble plate rotation preventing mechanism in the radial direction and the rotational direction is suppressed, uniform and continuous contact of the plurality of balls operating for power transmission can be realized, and a compact, easy-to-machine and inexpensive wabble plate type variable displacement compressor exhibiting good durability and silent performance can be provided.
    • 摇摆板式可变排量压缩机包括摆动板的旋转防止机构,其包括:(a)沿轴向可移动地设置的内环,但是防止旋转,支撑内径部分处的主轴相对旋转并移动 相对地在轴向方向上并且具有用于引导用于动力传递的多个滚珠的多个引导槽,(b)用作摆动板的摆动运动的摆动中心构件的套筒,其设置在主轴上以相对旋转 并且沿轴向移动并且沿轴向可移动地与内圈接合,(c)外环,其具有多个引导槽,用于在与内环中相对的引导槽相对的位置处引导滚珠,所述引导槽被支撑在套筒 摇摆地支撑摇摆板固定在外圆周上并通过轴承可旋转地支撑斜盘,和(d) 由形成在内圈和外圈中的引导槽保持的球并被压缩在引导槽之间以传递动力。 当作为摆动板旋转防止机构设置在径向和旋转方向上的均匀运动关节的作用被抑制时,可以实现用于动力传递的多个球的均匀且连续的接触,并且紧凑,容易 可以提供具有良好的耐久性和无声性能的机器和廉价的摇摆板式可变排量压缩机。
