Abstract

PURPOSE:To transfer a fluid to one direction alone through action by both suction and discharge valves installed at both ends of a tube, by setting up each of electromagnets in and around both ends of a nonexciting magnetic tube containing a magnetic fluid. CONSTITUTION:A solution containing a magnetic pulverulent body, namely, a magnetic fluid 2 is housed inside a nonexciting magnetic tube 1 made up in U- shaped form. At the vicinity of both ends 1', there are provided with each pair of electromagnets 3, while an exciting circuit 4, which gives magnetic force to these electromagnets in an alternate manner, is connected in line. Likewise, at both these ends 1' of the tube, there are provided with each pair of suction check valves 5 and discharge check valves 6. With these electromagnets 3 and the exciting circuit 4, when the magnetic fluid 2 reciprocates inside the tube 1, a liquid body is trabsferred from a pump suction port 7 to a pump discharge port 8 by action of these suction and discharge check valves 5 and 6.

【発明の詳細な説明】 本発明は、磁性流体を利用した容積形ポンプまたはプロ
ワ−に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a positive displacement pump or blower that utilizes magnetic fluid.

不具合を有する。Conventional positive displacement pumps or blowers, whether they are reciprocating type such as a piston type or 4I type such as a two-vane type, all (1) have a large amount of noise from the sliding parts, and (2) have a poor external shape. It has some disadvantages such as being difficult to change depending on the purpose.

積形ポンプまたはプロワ−を提供するものである。The present invention aims to solve the above-mentioned problems, and by disposing electromagnets near both ends of a non-excitable tube containing a magnetic fluid and energizing them alternately, the magnetic fluid is caused to reciprocate and its action is achieved. The present invention provides a positive displacement pump or blower that is used to transfer fluid.

Transfer fluid. At this time, (1) there is almost no noise as there are no sliding parts between the solid parts, and (2) the external shape can be made freely depending on the purpose.

The drawing is a sectional view of a positive displacement pump to which the present invention is applied, and in the drawing, 1 is a U-shaped non-excitable tube;
A solution containing magnetic powder, a magnetic fluid 2, is built in, and a pair of electromagnets 3 are provided near 1° on both ends, and an excitation circuit 4 that alternately applies magnetic force is connected to the electromagnets 3. has been done. Furthermore, a pair of suction check valves 5 and a pair of discharge check valves 6 are provided at 1° at both ends of the pipe. 6 is piped to the pump discharge port 8.

The fluid is sucked in through the suction check valve 5, and when the empty space is reduced, it is discharged through the discharge check valve 6 to the pump outlet 8. Sucking,
Since backflow of liquid does not occur due to the action of the discharge return volume valves 5 and 6, liquid is always transferred from the pump suction lower to the pop discharge D8.

Furthermore, if there is a possibility that the fluid may mix with the magnetic fluid 2 within the tube 1, the tube 1 is partitioned with a liquid layer or a floating plate that does not mix with both fluids.
