A vane pump comprising a central shaft adapted to receive a rotational force from the outside, a ring gear formed in a hollow portion provided in the shaft, a linear gear formed on one end of a constant velocity coupling and meshed with the ring gear, and a ring gear formed in a hollow portion of an inner rotor and meshed with a linear gear formed on the other end of the constant velocity coupling, whereby it is rendered possible to rotate the shaft and inner rotor at an equal speed, insert a circular portion formed at one end of a vane into a circular hollow space of the inner rotor, bring the other end of the vane into contact with an inner surface of an outer rotor, and vary the volumes of a compression chamber and a supply chamber, the air being thereby compressed, so that high-pressure compressed air can be obtained by a small-volume vane pump without encountering the collision of parts causative of noise.
一种叶片泵,包括一个中央轴,适用于从外部接收旋转力,轴上设有一个空心部分中形成的环齿,一个线性齿轮形成在恒速联轴器的一端,并与环齿啮合,一个环齿形成在内转子的空心部分中,并与恒速联轴器的另一端形成的线性齿轮啮合,从而使得轴和内转子能够以相同的速度旋转,将一个叶片的一端形成的圆形部分插入内转子的圆形空心空间中,将叶片的另一端与外转子的内表面接触,改变压缩腔和供给腔的容积,从而压缩空气,使得可以通过小体积叶片泵获得高压压缩空气,而不会遇到产生噪音的零部件碰撞。
