| 摘要 |
<p>The present invention discloses a balanced rotary machine for transferring fluid comprising at least one operational volume bounded by a cardioidal cross section; at least one inlet (29) to said operational volume; at least one outlet (32) from said operational volume; a single vane (2) situated within the operational volume and mounted upon a rotating axis (23); a means (22) of driving the axis of the vane (2) around a circular path within the operational volume; and a means (19) of rotating the vane (2) around its axis during the operating cycle. The machine is provided in a manner that the extremities of said vane (2) remain in contact with the walls of the operational volume throughout the operating cycle of the rotary machine thereby dividing the operational volume into at least two sections (3,30). The invention also presents an efficient method of transferring fluid with the aforesaid balanced rotary machine.</p> |
