摘要： A solenoid valve includes a linear solenoid and a ring-shaped rubber packing. The solenoid includes a yoke, an outer connector, a volume changing chamber, and a breathing passage. The yoke is made of a magnetic material and formed in a generally cylindrical cup shape having a cup-bottom part and a cup-opening part. The cup-opening part includes a notch. The connector is made of resin and exposed from the notch to an outside of the yoke. Volume of the chamber is changed in accordance with operation of the solenoid. The passage is formed inside the solenoid, and communicates with the chamber. The passage includes an outer opening, which opens into the outside of the yoke and is located at a fitted part between the yoke and the connector. The packing is attached around a base of the connector, where the yoke and the connector are fitted together.

摘要： An accommodating base material and an attracting base material are coaxially arranged, and are resin-insert-molded, thereby forming a bobbin base material. Next, inner peripheries of the accommodating base material, attracting base material and bobbin base material are cut, so that the accommodating base material, attracting base material and bobbin base material have same inner diameters. As a result of the cut-forming process, an accommodating member, an attracting member and a bobbin are formed. After insert-molding, the accommodating base material, attracting base material and bobbin base material are cut to have the same inner diameters. Thus, the accommodating member and the attracting member are accurately coaxially formed.

摘要： An electromagnetic actuator has a stator core, an armature and a coil. The stator core is formed as a seamless cylindrical tube having a thin wall as a magnetic restrictor. The thin wall has a thickness sufficient to maintain a mechanical strength of the stator core. A permanent magnet is located on an outside of the thin wall to generate a magnetic flux passing through the thin wall in the same direction as a magnetic flux generated by the coil. The thin wall is magnetically saturated with the magnetic flux generated by the permanent magnet. When the coil is energized, a magnetic flux generated by the coil gets around the saturated thin wall and passes through the armature.

摘要： A plunger is axially intersectable with a tubular recessed portion formed in a magnetically attracting core of a stator core upon slide movement of the plunger, which places a predetermined portion of the plunger into the tubular recessed portion. A magnetic material in the predetermined portion of the plunger may have a predetermined outer diameter that is smaller than an outer diameter of the magnetic material in a slidably contacting portion of the plunger, which slidably contacts a slidable core of the stator core. Alternatively, a magnetic material in the tubular recessed portion may have a predetermined inner diameter that is larger than an inner diameter of the magnetic material in a slidably contacting portion of the slidable core, which slidably contacts the plunger.

摘要： In an electromagnetic hydraulic control valve for driving a spool type valve by means of an electromagnetic actuator, the electromagnetic actuator has a plunger and a core stator which slide on each other. Therefore their magnetic efficiency along their radial directions gets better and magnetic radial force generated at the plunger is suppressed to a constant level. Thus, increase of hysteresis in a high stroke range can be suppressed. In addition, magnetic radial force along the radial direction is stably generated even in a low stroke range, because of magnetic efficiency. This suppresses vibration of the plunger, and therefore an orifice used conventionally can be disused. By disusing the orifice, the influence of the viscosity of oil is reduced and a response of the spool at low temperature can be improved.
