摘要:
The conventional linear drive apparatus has the problem that in constructing a linear motor of a multiphase structure by connecting a plurality of armature units, the length of the armature becomes longer in proportion to the number of the phases, thus limiting the locations where the apparatus can be installed. The problem is solved by a linear drive apparatus comprising a plurality of armature units 3 formed by a magnetic material on which a conductor coil 4 is disposed, and an armature comprising an arrangement of the armature units 3. The armature units 3 comprise a plurality of opposing portions having opposing magnetic pole teeth. The magnetic pole teeth of adjacent opposing portions are arranged in an interdigitated manner. A secondary member 6 is disposed between magnetic pole teeth of the opposing portions. The armature units 3 comprise the coil 4 arranged on opposite sides thereof in an alternating manner.

Disclosed herewith a compact linear motor provided with a plurality of magnetic pole teeth and used to increase the thrust force by canceling a magnetic attractive force working between the primary member and the secondary member. The linear motor comprises a primary member and a secondary member. The primary member includes cores formed with a magnetic material and an electromagnetic coil wound on the cores while the secondary member supported so as to be capable of moving relatively with respect to the primary member with a gap therebetween. In the linear motor, the coil that is wound commonly on the cores is also disposed between adjacent magnetic pole teeth.

A drive apparatus overcomes the problems of ensuring accurate mounting of a plurality of armature coils relative to a plurality of magnetic pole position detectors, limitations concerning the location for mounting, and the extension of primary-side length. The drive apparatus comprises a primary side including an arrangement of a plurality of armatures each having a core made of a magnetic material with coil windings. It also comprises a secondary side including a permanent magnet movably supported relative to the armatures via a gap. A magnetic pole position detector is disposed between adjacent armatures.

A linear motor for generating a linear motion in a linear direction, has a plurality of first members, each of which includes an electromagnetic coil for generating a first magnetic field, and a magnetic core (magnetically permeable) having magnetic surfaces being opposite to each other so that the first magnetic field passes a space between the magnetic surfaces, and a second member arranged in the spaces to be relatively movable linearly with respect to a combination of the first members to generate the linear motion in the linear direction, and including a magnet polarized in a polarizing direction to generate a second magnetic field.

A relationship between an inner diameter A of a sac volume and a distance from a central axis of the sac volume is set to satisfy a condition of 1≦A/2B≦20. In this way, fuel, which flows from the sac volume into each injection hole, will be injected from the injection hole without being spaced from a wall surface of a valve body, which form the injection hole. Thus, it is possible to limit adhesion of a foreign substance to a wall surface of each injection hole. Furthermore, even if the foreign substance is adhered to the wall surface of the injection hole, the foreign substance can be removed by the fuel, which flows through the injection hole.
