The working chamber 13 in this embodiment is of non-circular design in cross-section.
The rotating shaft 2 is arranged in the working cavity 13 of the shell 1 and can rotate around a fixed axis, and the diameter of the rotating shaft 2 is smaller than the inner diameter of the working cavity 13, so that the working cavity 13 is large enough to meet the requirement of fluid acceleration. The shaft 2 is provided with a through hole (not shown) penetrating in the radial direction, and the outer peripheral portion of the shaft 2 is always in sealing contact with the inner wall of the working chamber 13, thereby isolating the suction port 131 and the discharge port 132. The outer end of the rotating shaft 2 can be connected with a driving mechanism not shown in the figure. The driving mechanism in this embodiment may be a motor, or the driving mechanism may include a motor and a transmission connected to the motor, and a power output end of the transmission is connected to the rotating shaft 2.
The compression plate 3 is in sliding fit in the through hole, and at least one end of the compression plate extends out of the rotating shaft 2, under the state of figure 5, one end of the compression plate 3 extends out of the rotating shaft 2, and under other states, the compression plate 3 has two ends extending out of the rotating shaft 2. As shown in fig. 4, both ends of the compression plate 3 are always in sealing contact with the inner wall of the working chamber 13, so that a first isolation chamber 31 and a second isolation chamber 32 are formed in the working chamber 13; the compression plate 3 has two ends that are intersected by two inclined surfaces 33 (as shown in fig. 5).
