TECHNICAL FIELD The present invention relates to fluid pumps and motors, and more particularly to rotatable fluid pumps and motors. The fluid pump sucks and discharges the fluid while the shaft rotates by the actuator, and the fluid motor receives the fluid discharged from the pump and rotates the shaft. The fluid pump and the fluid motor have almost the same structure.

Conventional rotary pumps include vane pumps with sliding vanes, gear pumps with two gears engaged therewith, and screw pumps. Among them, the vane pump is relatively simple in structure and is frequently used. However, in the conventional vane pump, the vanes had to be configured to be able to stand out from the rotor. In addition, the vane pump has a structural problem such that the rotating shaft is eccentric to cause vibration and the bearing is easily damaged due to an unbalanced load applied to the rotating shaft. And the pulsation occurs because the fluid is not continuously discharged.

It is an object of the present invention to provide a rotary fluid pump having vanes and having an uneccentric structure. Another object of the present invention is to provide a rotatable fluid pump having vanes having a simpler structure since it does not require the appearance. Still another object of the present invention is to provide a rotational fluid pump without pulsation. It is yet another object of the present invention to provide a fluid pump with less wear on the contacts. Still another object of the present invention is to provide a fluid pump that can also be used as a motor.

The unit roller 59 also has a cylindrical shape, and a plurality of unit rollers 59 are stacked to form a contact roller member 58. This configuration of the contact roller member 58 causes each unit roller 59 to be rotated separately. Therefore, the unit rollers 59 are rotated separately at an appropriate speed in accordance with the difference in the linear speed in the radial direction of the vanes 34 (the linear speed becomes faster toward the outside in the radial direction). This provides the effect of reducing the wear between the vanes 34 and the contact roller member 58. The first linear movable member 50 is accommodated in the first guide grooves 265 of the housing 20 and the first guide passages 72 and 82 of the first and second contact members 70 and 80 so as to be rotated.

Specifically, since the rotor is not eccentric, no vibration occurs and the bearings are not easily damaged. And because the vane is not in the form of haunting, the structure is simple. In addition, since suction and discharge are performed continuously, there is no pulsation, thereby providing a stable discharge pressure. And since it does not require a check valve, it can be easily converted to a fluid motor. In addition, since the roller member in contact with the vane is formed of a plurality of unit rollers, wear can be reduced.
