Description

本発明は、電磁石により交番磁界を発生させることによってピストンを直線往復動させるようにしたポンプやコンプレッサなどの電磁往復動流体装置に関する。 The present invention relates to an electromagnetic reciprocating fluid device such as a pump or a compressor that linearly reciprocates a piston by generating an alternating magnetic field with an electromagnet.

この種電磁往復動流体装置では、ピストンに連結される可動部材（ピストンロッド）に磁性材からなる磁力吸引部が設けられ、電磁石が周期的に発生し該磁力吸引部に作用する電磁吸引力と、該電磁吸引力により該磁力吸引部が吸引される方向と反対の方向に付勢するバネ力とによって当該可動部材を往復動するようにした形式のものと、可動部材に永久磁石を組み込み、電磁石が生じる交番磁界によって該永久磁石を吸引・反発させることにより当該可動部材を往復動させるようにした形式のものとがある。 In this type of electromagnetic reciprocating fluid device, a magnetic attraction part made of a magnetic material is provided on a movable member (piston rod) connected to a piston, and an electromagnetic attraction force that is generated periodically and acts on the magnetic attraction part. , A type in which the movable member is reciprocated by a spring force biased in a direction opposite to the direction in which the magnetic attractive portion is attracted by the electromagnetic attractive force, and a permanent magnet is incorporated in the movable member, There is a type in which the movable member is reciprocated by attracting and repelling the permanent magnet by an alternating magnetic field generated by an electromagnet.

可動部材は、その往復動路の両側に対向配置される電磁石の間に微小隙間を介して配置されるので、その微小空間を維持することが必要となる。このため、上記第１番目の形式のものでは、例えば、可動部材の両端を摺動可能に支持することによりその維持を図るようにしたものがある（特許文献１）。 Since the movable member is arranged through a minute gap between the electromagnets arranged opposite to both sides of the reciprocating path, it is necessary to maintain the minute space. For this reason, in the thing of the said 1st type, there exist some which aimed at the maintenance by supporting the both ends of a movable member so that sliding is possible (patent document 1).

また、上記第２番目の形式のものでは、当該可動部材が永久磁石を備えるために、上記往復動方向での吸引力・反発力のほかに、往復動方向に対する横断方向での力が作用するために、該可動部材の長手中心軸線を中心にした回転トルクが生じる可能性がある。可動部材に取り付けられる永久磁石は一般的に断面四角形のものとされ、従って、回転トルクにより長手中心軸線の周りで傾けられると、一方の電磁石への吸引力が強くなり、該電磁石との摩擦が生じたりする。一般的には、可動部材の両端は、円形断面のピストンとこれを摺動可能に収納したシリンダとにより支持するようにしているため、長手中心軸線の周りでの傾きを阻止することはできない。これを回避するために、可動部材の両端を往復動の方向には柔軟で軸線回りには剛性を有するダイヤフラムや十字形のバネのバネ支持具で支持するようにしたものが提案されている（特許文献２参照）。しかし、このような部材による支持では、可動部材の長手軸線方向での動きが制限され、流体装置としては好ましくない。 In the second type, since the movable member includes a permanent magnet, a force in the transverse direction to the reciprocating direction acts in addition to the attractive force / repulsive force in the reciprocating direction. Therefore, there is a possibility that rotational torque about the longitudinal center axis of the movable member is generated. The permanent magnet attached to the movable member is generally of a rectangular cross section. Therefore, when the permanent magnet is tilted around the longitudinal central axis by the rotational torque, the attractive force to one of the electromagnets increases, and the friction with the electromagnet is reduced. It occurs. In general, since both ends of the movable member are supported by a piston having a circular cross section and a cylinder in which the movable member is slidably housed, tilting around the longitudinal central axis cannot be prevented. In order to avoid this, there has been proposed one in which both ends of the movable member are supported by a spring support of a diaphragm or a cross-shaped spring that is flexible in the direction of reciprocating motion and rigid around the axis ( Patent Document 2). However, the support by such a member restricts the movement of the movable member in the longitudinal axis direction, which is not preferable as a fluid device.

以下、本発明の実施形態を添付図面に基づき説明する。 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

図１から図３に本発明に係る電磁往復動流体装置１０の第１の実施形態を示す。図１は図２のＩ−Ｉ線断面図、図２は図１のII−II線断面図、図３は図１のIII−III線断面図である。 1 to 3 show a first embodiment of an electromagnetic reciprocating fluid device 10 according to the present invention. 1 is a cross-sectional view taken along line II in FIG. 2, FIG. 2 is a cross-sectional view taken along line II-II in FIG. 1, and FIG. 3 is a cross-sectional view taken along line III-III in FIG.

図１及び図２から分るように、この電磁往復動流体装置１０は、左右両側位置にある第１及び第２ピストンシリンダアセンブリ１２、１２´と、中央位置にある駆動部１４とを有する。 As can be seen from FIGS. 1 and 2, the electromagnetic reciprocating fluid device 10 includes first and second piston cylinder assemblies 12 and 12 ′ located at both left and right positions, and a drive unit 14 located at a central position.

第１及び第２ピストンシリンダアセンブリ１２、１２´は、それぞれ、シリンダ１６、１６´及びピストン１８、１８´を備え、該ピストンが該シリンダ内で（図１及び図３で見て）左右方向に往復動されることにより、空気等の流体を図１に矢印で示すように、中央ハウジング２０に設けた入口２１から吸引し、逆止弁２２、２２´を介して当該流体装置１０の左右両端に設けられた出口２４、２４´から排出するようになっている。 The first and second piston cylinder assemblies 12, 12 'include cylinders 16, 16' and pistons 18, 18 ', respectively, with the pistons in the left-right direction (as viewed in FIGS. 1 and 3). By being reciprocated, a fluid such as air is sucked from an inlet 21 provided in the central housing 20 as indicated by an arrow in FIG. 1, and both left and right ends of the fluid device 10 through check valves 22 and 22 ′. It discharges | emits from the exit 24,24 'provided in this.

図１から分るように、左右のシリンダ１２,１２´は、その左右方向に延びる長手軸線が相互に間隔ａだけずらして配置されている。 As can be seen from FIG. 1, the left and right cylinders 12, 12 ′ are arranged such that longitudinal axes extending in the left-right direction are shifted from each other by a distance a.

ピストン１８、１８´は、図２及び図３に示すように全体的に平板状とされ、一対の永久磁石２６、２６´を備えた可動部材２７によって連結されている。永久磁石２６、２６´は、図２で見て左右両側にＮ極及びＳ極が着磁されるが、左側の永久磁石２６と右側の永久磁石２６´とは、相互に逆に着磁される。すなわち、両磁石を図１の手前側から見た場合、その見える側の面は、例えば一方の永久磁石２６ではＮ極、他方の永久磁石２６´ではＳ極となり、図１の裏面側から見た場合、永久磁石２６の面はＳ極、永久磁石２６´の面はＮ極とされる。 As shown in FIGS. 2 and 3, the pistons 18 and 18 ′ have a flat plate shape as a whole, and are connected by a movable member 27 including a pair of permanent magnets 26 and 26 ′. The permanent magnets 26 and 26 'are magnetized with N and S poles on the left and right sides as viewed in FIG. 2, but the left permanent magnet 26 and the right permanent magnet 26' are magnetized in reverse to each other. The That is, when both magnets are viewed from the front side in FIG. 1, the surface on the side to be viewed is, for example, the N pole in one permanent magnet 26 and the S pole in the other permanent magnet 26 '. In this case, the surface of the permanent magnet 26 is an S pole, and the surface of the permanent magnet 26 'is an N pole.

装置中央の駆動部１４は、図２及び図３に示すように、可動部材２７の両側に設定された一対の電磁石２８、２８´を備えている。各電磁石は、Ｅ型鉄心３０と、該Ｅ型鉄心の中央磁極３０ａの周りで巻枠３２に卷回されたコイル３４とを有している。両電磁石の中央磁極及び左右側部磁極３０ｂ、３０ｃは、可動部材２７に対して微小な空隙をあけて相互に対向配置されている。 As shown in FIGS. 2 and 3, the drive unit 14 at the center of the apparatus includes a pair of electromagnets 28, 28 ′ set on both sides of the movable member 27. Each electromagnet includes an E-type iron core 30 and a coil 34 wound around a winding frame 32 around a central magnetic pole 30a of the E-type iron core. The center magnetic poles and the left and right side magnetic poles 30 b and 30 c of both electromagnets are arranged to face each other with a minute gap with respect to the movable member 27.

電磁石２８、２８´に電流を通して、例えば電磁石２８の中央磁極にＳ極、左右磁極にＮ極が発生し、これらに対向する電磁石２８´の中央磁極にはＮ極、左右磁極にＳ極が発生するようにする。このとき、永久磁石２６は中央磁極から反発力、左の側部磁極から吸引力を受け、永久磁石２６´は中央磁極から吸引力、右の側部磁極から反発力を受けて、可動部材２７とともに全体として図１の矢印Ｍで示す左方向に動くような力を受ける。従って、これら電磁石に交番電流をかけることにより、中央磁極及び左右磁極に相互に逆極性の磁極が発生し、これにより、前述の磁石保持部材の永久磁石は左右に駆動され、ピストン１８、１８´はシリンダ内で摺動し、図１に矢印で示す如き流体の流れを生じる。 By passing an electric current through the electromagnets 28 and 28 ', for example, an S pole is generated at the central magnetic pole of the electromagnet 28 and an N pole is generated at the left and right magnetic poles. To do. At this time, the permanent magnet 26 receives a repulsive force from the central magnetic pole and an attractive force from the left side magnetic pole, and the permanent magnet 26 ′ receives an attractive force from the central magnetic pole and a repulsive force from the right side magnetic pole, thereby moving the movable member 27. At the same time, it receives a force that moves in the left direction indicated by an arrow M in FIG. Therefore, by applying an alternating current to these electromagnets, magnetic poles having opposite polarities are generated in the central magnetic pole and the left and right magnetic poles, whereby the permanent magnets of the aforementioned magnet holding members are driven left and right, and the pistons 18, 18 ' Slides in the cylinder and produces a fluid flow as shown by the arrows in FIG.

ところで、本実施形態のように鉄心３０の磁極面と対向する永久磁石２６、２６´の面が平面状である場合には、一対の電磁石２８、２８´と永久磁石２６、２６´との吸引力がちょうど釣り合う中立点の位置を除いて、可動部材２７を図２の矢印Ｒのいずれかの方向に回転させるような回転トルクが作用するので、これに抗する力を作用させない場合には磁石２６、２６´または可動部材２７が電磁石２８、２８´またはその他の固定している部材と接触する虞がある。本実施形態においては、前述の如く、第１、第２ピストンシリンダアセンブリ１２、１２´の中心軸線５８及び５９を同軸状とせず、可動部材２７の中心軸６０に対してそれぞれ距離ａだけ上下にオフセットさせて配置してあるので、回転トルクに抗することができ、当該可動部材の回転を防ぐことができる。 By the way, when the surfaces of the permanent magnets 26 and 26 ′ facing the magnetic pole surface of the iron core 30 are planar as in the present embodiment, the attraction between the pair of electromagnets 28 and 28 ′ and the permanent magnets 26 and 26 ′. Except for the position of the neutral point where the force just balances, a rotational torque that rotates the movable member 27 in any direction of the arrow R in FIG. 2 acts, so if no force against this is applied, a magnet 26, 26 'or the movable member 27 may come into contact with the electromagnets 28, 28' or other fixed members. In the present embodiment, as described above, the central axes 58 and 59 of the first and second piston cylinder assemblies 12 and 12 ′ are not coaxial, and are vertically moved by a distance a with respect to the central axis 60 of the movable member 27. Since they are arranged offset, it is possible to resist rotational torque and to prevent the movable member from rotating.

尚、図示の実施形態においては、ピストンシリンダアセンブリ内に圧縮コイルバネ６２を配置してある。これは、永久磁石２６、２６´、可動部材２７およびピストン１８、１８´からなる可動部分の軸線方向（図１の左右方向）中央に向かう付勢力を与えるものである。すなわち、これは、例えば、電磁石２８，２８´に電流が流されず電磁力が加わっていないときに、永久磁石が左右どちらかの側部磁極に引き付けられて止まっている場合があり、そのときバネ部材は撓んでいるので、その状態で電磁力が加わったとき、撓んでいるバネ部材の付勢力により可動部材が動き出すのを補助するようにする。また、可動部分の質量と圧縮コイルバネ６２のバネ定数とで定まる固有振動数をバネ定数の選択によって任意に設定することを可能とする。 In the illustrated embodiment, a compression coil spring 62 is disposed in the piston cylinder assembly. This gives an urging force toward the center in the axial direction (left-right direction in FIG. 1) of the movable part composed of the permanent magnets 26, 26 ', the movable member 27, and the pistons 18, 18'. That is, for example, when no current is applied to the electromagnets 28 and 28 'and no electromagnetic force is applied, the permanent magnet may be attracted to the left and right side magnetic poles and stopped. Since the spring member is bent, when an electromagnetic force is applied in this state, the movable member is assisted by the urging force of the bent spring member. Further, the natural frequency determined by the mass of the movable part and the spring constant of the compression coil spring 62 can be arbitrarily set by selecting the spring constant.

図４から図７には本発明に係る電磁往復動流体装置１１０の第２の実施形態が示されている。図４は図５のIV‐IV線断面図、図５は図４のＶ‐Ｖ線断面図、図６は図４のVI‐VI断面図、図７は図４のVII‐VII線断面図である。この電磁往復動流体装置１１０は、全体的構成としては、前述の第１の実施形態のものと同じであり、従って、同じ構成要素には同じ参照番号を付して示してある。この電磁往復動流体装置１１０で特徴とするところは、前述の実施形態において平板状にされていた永久磁石２６、２６´を、円柱状、図示の例では、軸線方向での長さが短く円盤状にした点にある。この円盤状の永久磁石２６、２６´は、円柱状とされた可動部材２７と同軸状に設定されており、可動部材２７の両端に設定される第１及び第２ピストンシリンダアセンブリ１２，１２´も同軸状にされている。 4 to 7 show a second embodiment of the electromagnetic reciprocating fluid device 110 according to the present invention. 4 is a sectional view taken along line IV-IV in FIG. 5, FIG. 5 is a sectional view taken along line VV in FIG. 4, FIG. 6 is a sectional view taken along line VI-VI in FIG. It is. The electromagnetic reciprocating fluid device 110 is generally the same as that of the first embodiment described above, and therefore, the same components are denoted by the same reference numerals. The electromagnetic reciprocating fluid device 110 is characterized in that the permanent magnets 26 and 26 ', which have been flat in the above-described embodiment, are formed in a cylindrical shape, and in the illustrated example, the length in the axial direction is short. The point is in the shape. The disk-shaped permanent magnets 26 and 26 ′ are set coaxially with a cylindrical movable member 27, and the first and second piston cylinder assemblies 12 and 12 ′ are set at both ends of the movable member 27. Is also coaxial.

該円盤状磁石２６,２６´は、図５および図６に示すように、該円盤状磁石の中心軸線を含む仮想平面１５０および１５２で分けられた両側部分が相互に反対の極性となるように着磁される。仮想平面１５０，１５２は、中心軸線を通る（図５及び図６で見て）垂直な面に対してそれぞれ反対方向に所定角度だけ傾けて設定されている。 As shown in FIGS. 5 and 6, the disk-shaped magnets 26 and 26 ′ are arranged such that both side portions separated by virtual planes 150 and 152 including the central axis of the disk-shaped magnet have opposite polarities. Magnetized. The virtual planes 150 and 152 are set so as to be inclined by a predetermined angle in opposite directions with respect to a vertical plane passing through the central axis (as viewed in FIGS. 5 and 6).

上述したような構成において、電磁石１３０、１３２の中央磁極１３４ａ、１３６ａが相互に反対の極性となるように（例えば中央磁極１３４ａがＮ極となり中央磁極１３６ａがＳ極となるように）コイル１４２、１４４に通電すると、該円盤状磁石２６は該中央磁極１３４ａ、１３６ａに吸引され、他方の円盤状磁石２６´は中央磁極部分１３４ａ、１３６ａから反発され、同時に該円盤状磁石２６´は右側部磁極１３４ｂ、１３６ｂに吸引される。円盤状磁石２６及び２６´が受ける磁気力の合力は、図４の右方向に向かう力であって、円盤状磁石とそれらが固定されている可動部材２７及びその両端に連結された第１ピストン１８並びに第２ピストン１８´とからなる可動部１１２を図４の右方向に移動させることになる。 In the configuration as described above, the coil 142, the central magnetic poles 134a, 136a of the electromagnets 130, 132 have opposite polarities (for example, the central magnetic pole 134a becomes the N pole and the central magnetic pole 136a becomes the S pole). When the current 144 is energized, the disk-shaped magnet 26 is attracted to the central magnetic poles 134a, 136a, and the other disk-shaped magnet 26 'is repelled from the central magnetic pole portions 134a, 136a, and at the same time, the disk-shaped magnet 26' 134b and 136b are sucked. The resultant force of the magnetic forces received by the disk-shaped magnets 26 and 26 'is a rightward force in FIG. 4, and is the disk-shaped magnet, the movable member 27 to which they are fixed, and the first piston connected to both ends thereof. 4 and the second piston 18 'are moved in the right direction in FIG.

該可動部１１２が図４の右方向に移動して、該円柱状磁石２６´と右側磁極１３４ｂ、１３６ｂとが正対する位置関係になったとき、次に可動部１１２を図４の左方向に移動するための力を発生させるために、該コイル１４２、１４４には上記と反対方向の電流が印加される。そうすると、図５に示されている円盤状磁石２６に対しては図中左側の電磁石１３０の中央磁極部分１３４ａがＮ極となり対向する中央磁極部分１３６ａはＳ極となって、該円盤状磁石２６が反時計回りの方向に回転するようなトルクＴ１が作用する。同様にして、図６に示されている円盤状磁石２６´に対しては時計回りの方向に回転するようなトルクＴ２が作用する。すなわち、円柱状磁石２６と２６´とに作用するトルクはお互いに反対方向に回動させようとする回転トルクであり、これらが相殺し合うため可動部１１２全体として可動方向軸周りのいずれか一方に回転することがないようにすることができる。 When the movable portion 112 moves to the right in FIG. 4 and the cylindrical magnet 26 ′ and the right magnetic poles 134b and 136b are in a positional relationship, the movable portion 112 is next moved to the left in FIG. In order to generate a force for movement, a current in the direction opposite to the above is applied to the coils 142 and 144. Then, with respect to the disc-shaped magnet 26 shown in FIG. 5, the central magnetic pole portion 134a of the electromagnet 130 on the left side in the drawing becomes the N pole and the opposed central magnetic pole portion 136a becomes the S pole, so that the disc-shaped magnet 26 Torque T1 is applied so that the motor rotates counterclockwise. Similarly, a torque T2 that rotates in the clockwise direction acts on the disk-shaped magnet 26 'shown in FIG. That is, the torque acting on the columnar magnets 26 and 26 'is a rotational torque that tries to rotate in the opposite directions to each other. Can be prevented from rotating.

さらに本実施形態において、固定電磁石１３０、１３２の鉄心１３４、１３６は、単一の形状を有するケイ素鋼板等の薄板を、磁極部分が円盤状磁石２６、２６´と適当な間隙で対向するようにずらしながら積層して構成されている。このように構成して本体ケーシング１２０に固定用ネジ１５６で固定できるようにネジ穴を形成するため、該鉄心１３４、１３６を構成する薄板に設けた固定用ネジ穴部１５４は図７に示すように長孔形状で作成されている。 Further, in the present embodiment, the iron cores 134 and 136 of the fixed electromagnets 130 and 132 are made of a thin plate such as a silicon steel plate having a single shape so that the magnetic pole portion faces the disk-shaped magnets 26 and 26 'with an appropriate gap. It is constructed by laminating while shifting.
