流電源を示す。 However, in this type of vibratory compressor, the drive unit 10 that reciprocates the piston 4 is formed by a so-called voice coil type linear motor.
The configuration of this drive section 10 will be explained below. first,
On the other end side of the housing 1, an internally magnetized single-pole magnetic circuit A is formed, which is composed of a permanent magnet 11, a pole piece 12, and a yoke 13. In this case, the yoke 13 forms the other end side of the housing 1. are doing. A movable electromagnetic coil 14 is disposed within the magnetic circuit A, and the movable electromagnetic coil 14 is connected to the piston 4 via a connecting member 15. Further, 15a and 15b are resonance springs, and 16 is an AC power source for the movable electromagnetic coil 14.

いる。 The driving section 20 of the piston 4 is constructed on the outer periphery of the cylinder, and B is the magnetic circuit of this embodiment. This magnetic circuit B is first connected to cylinder 3.
A pole piece 21 is fitted onto the outer surface of the pole piece 21, and permanent magnets 22a and 22b made of ferrite magnets are arranged on the outside of the pole piece 21.
These permanent magnets 22a and 22b are spaced apart from each other in the axial direction of the cylinder 3, and are connected to each other via a yoke 23, so that the pole piece 21, the permanent magnet 22
The above-mentioned magnetic circuit B is constituted by a, 22b and a yoke 23. Further, in this embodiment, the yoke 23 constitutes a part of the housing 1.

いることはもちろんである。 In the magnetic circuit B, movable electromagnetic coils 24a and 24b are arranged. These movable electromagnetic coils 24a, 24b are positioned between the pole piece 21 and each permanent magnet 22a, 22b, respectively, and are designed to vibrate synchronously. That is, the movable electromagnetic coil 24
If the winding directions of the movable electromagnetic coils a and 24b are the same, these movable electromagnetic coils 24a and 24b are connected to the AC power source 16 in opposite directions as shown by the imaginary line X. Similarly, 15a and 15b represent resonance springs, and 25 is an end plate of the housing 1. Further, members such as the housing 1 and the cylinder 3 are made of a non-magnetic material with a small specific gravity such as an aluminum alloy, which naturally reduces the weight of the entire device.

により表わされる。 According to the drive unit 20 having the above configuration, the alternating thrust F acting on the movable electromagnetic coils 24a and 24b has the average magnetic flux density of the gap as Bg, the current flowing through the movable electromagnetic coil as i, and the average length of one turn of the coil as Bg. When the number of turns of the above coil is N, it is expressed by the following formula: F=BgilN.

L2＝L11/2となる。 In other words, with respect to the coil width of the movable electromagnetic coil 14 indicated by L 1 in FIG. 1, the coil width L 2 of each movable electromagnetic coil 24a in this embodiment is L 2 =L 1 1/2.
一方、従来の磁気回路Ａの磁速φ1はφ1＝L1l、

Also, the magnetic flux φ 2 of the magnetic circuit B in this embodiment is φ 2 =L 2 l
These magnetic fluxes φ 1 ,
The relationship of φ 2 is φ 2 =φ 1 /2. Therefore, if the magnetic velocity densities of the yoke 13 of the conventional example shown in FIG. 1 and the yoke 23 of this embodiment are the same, then for the wall thickness t 1 representing the cross-sectional area of the yoke 13, as shown in FIG. The wall thickness t 2 of the yoke 23 in this embodiment is t 2 =t 1 /2.

その圧縮性能の向上を図ることができる。 Therefore, according to the above embodiment, the thickness t 2 of the yoke 23 in the magnetic circuit B of this embodiment can be halved compared to the conventional magnetic circuit A, so that the weight of the yoke 23, that is, the overall weight, can be significantly reduced. It can be done easily. Furthermore, since the yoke 23 connects the two polarized permanent magnets 22a and 22b, its length is also shorter than that of the conventional one.
This can greatly contribute to reducing overall weight. Moreover, by polarizing the permanent magnets 22a and 22b, the magnetic circuit B can be configured to be long without causing an increase in weight, thereby ensuring a large vibration stroke of the movable electromagnetic coils 24a and 24b, that is, a reciprocating stroke of the piston 4.
The compression performance can be improved.

い。 Note that the present invention is not limited to the above embodiment. For example, in the above embodiment, the permanent magnet is constructed with two poles, but the present invention is not limited to this, and in short, the magnetic circuit may have an external magnet type multi-pole structure.
また、圧縮機部の具体的構造は種々と変更して

種々の優れた効果を奏する。 As explained above, in this invention, the magnetic circuit is arranged outside the compressor section, and this magnetic circuit has a multipolar structure, so that the yoke is thicker than the conventional internal single-pole type magnetic circuit. The thickness can be halved and the overall weight can be significantly reduced. In addition, since the compressor section can be built inside the magnetic circuit, the overall length can be shortened and downsized, etc.
It has various excellent effects.
