Description

[Detailed Description of the Invention] Industrial Application Field The present invention provides a swash plate in which a disk inscribed in a spherical inner surface swings or rotates along a conical surface protruding into a space formed by the spherical inner surface. The present invention relates to an electromagnetic swash plate pump that swings or rotates the swash plate by electromagnetically attracting the swash plate to the conical surface.

Prior Art The conventional structure of a swash plate pump will be briefly explained using the structure disclosed in Japanese Patent Application Laid-Open No. 53-25904 as an example. In FIGS. The conical surface 3 protruding into the space to be formed is a disk whose outer peripheral edge contacts the spherical inner surface 1 and its flat surface contacts the conical surface 2 while turning around the conical surface 2. 4 is the rotation axis,
The disk 3 is pivoted around the conical surface 2.
If the rotating shaft 4 rotates in the direction of the arrow 5, 6 is an inlet port, and 7 is a discharge port, both of which open into the conical surface 2. 8 is a partition plate having a semicircular shape, and the part corresponding to the semicircular chord 8-1 always keeps in contact with the disk 3 and swings in the groove 9 to connect the spherical inner surface 1 and the The space formed by the conical surface 2 and the disk 3 is divided into a suction side pump action chamber and a discharge side pump action chamber. The groove 9 passes between the suction port 6 and the discharge port 7.

Relationship between the prior art and the present invention In the configuration disclosed in JP-A-53-25904 mentioned above, it is necessary that the disc 3 be rotated by a rotating shaft and mechanically connected to a drive source. In contrast to friction between the partition plate and the disc and between the conical surface and the disc, the present invention arranges a plurality of magnetic pole members each having a magnetic pole surface aligned with the conical surface in the order in which they are arranged. Accordingly, by sequentially magnetizing the magnetic pole faces and attracting the disc made of magnetic material, the disc is made to swing or rotate, and the mounting arrangement is possible without being constrained by the position of the drive shaft. There is no friction between the conical surface of the disk and the disk and the partition plate.

The operation of the first embodiment will be explained with reference to FIG. Now, if the magnetic pole surface of the magnetic pole member a of the magnetic pole member 105 is excited to the S pole, the disk 104 (not shown in FIG. 3) is attracted to the magnetic pole member a, and one surface of the disk 104 and one of the upright conical surfaces 103 are in contact. The direction of the contact line is indicated by a dashed line 115. Of course, the surface on the opposite side where the chain line 115 is extended to the opposite side from the center of the disk 104 contacts another upright conical surface 103, and the magnetic pole surface of the corresponding magnetic pole member is excited to the north pole. Next, when the magnetic pole member b is energized and the magnetic pole member a is demagnetized, the contact line 11
5 moves toward the magnetic pole member b, and when the same process is repeated, the contact line 115 turns in the direction of the arrow 116, and the partition plate 1 moves from the contact line 115 in the direction of the arrow 116.
The space leading to 14 forms a discharge side pump action chamber,
The opening 112 becomes a discharge port. Further, a space extending from the contact line 115 to the partition plate 114 in the direction opposite to the arrow 116 forms a suction-side pump action chamber, and the opening 110 serves as a suction port. Another pump formed on the other side of the disk 104 has an inlet 109 and an outlet 111.

Even if the two pumps formed in contact with both sides of the disk 104 are used independently,
09, 110, the two discharge ports 111, 112 may be combined and used as one pump. Since adjacent magnetic pole faces successively attract the disc 104, the mutual attraction distance is small, and the disc 104 can be easily rotated along the upright conical surface 103 by three-dimensional rocking.

FIG. 8 shows a fourth embodiment, in which an electrode rod 117 that reaches the upright conical surface 103 of the pump housing 101 is connected to the outside of the pump housing 101 as a means for sequentially energizing the excitation winding 106 without providing a distributor. the electrode rod 1.
17 and the disc 104 constitute a contact point. The electrode rod 117 is connected to the magnetic pole member 1 to be excited.
05, the excitation winding 106 is placed on the magnetic pole member 105 to which the disk 104 is to be attracted immediately after.
energized, the magnetic pole member 105 is excited and attracts the disk 104. At this time, the disk 104 comes into contact with the electrode rod 117 that energizes the excitation winding 106 of the magnetic pole member 105 to be excited next, and the disk 104 continues to rotate in the same manner to perform a pumping action. 118 is a switch; when the switch 118 is opened, the pumping action is stopped; when the switch 118 is closed, the pumping action is started.

The partition plate 114 is a partition including a radius extending from the center of the internal space of the pump housing 101 to the spherical surface 102 in a direction between the suction ports 109, 110 and the discharge ports 111, 112, as shown in FIG. Plate 114 may be fixed to pump housing 101 . At this time, disk 10
4 is formed with a slit 119 for slidably sandwiching the fixed partition plate 114 therebetween. Since the fixed partition plate 114 exists only on the radius of the internal space of the pump housing 101, the notch 114-1 is structurally irrelevant as in the case where the partition plate 114 exists on the diameter.

Effects By the configuration of the electrode swash plate pump of the present invention, (1) it is possible to provide a swash plate pump in which there is no slippage between the conical surface and the disk, and between the partition plate and the disk, and therefore no wear occurs.

(2) Since no mechanical connection is required between the drive source and the drive source, it can be installed in any position and provides flexibility in outfitting.
