Abstract: A movable core sliding in a guide portion includes a small outer-diameter part, a large outer-diameter part, and a protrusion part. When a magnetic circuit is generated by energizing a coil, a magnetic attractive force inclining with respect to a center axis of the guide portion is generated between the guide portion and the movable core, and moves the movable core towards a stator core. Then, a sliding portion, which is provided over the whole periphery of the small outer-diameter part, and the protrusion part of the movable core are abutted on an inner peripheral surface of the guide portion, a clearance is generated between an outer peripheral surface of parts of the movable core except the protrusion part and the inner peripheral surface of the guide portion. Since the valve member can be opened by a small magnetic attractive force, a coil assembly can be made small.

Abstract: A guide portion made of a magnetic material can be filled with a gaseous fuel of high-pressure and is slidably receiving a movable core. The guide portion is constructed by a first small-diameter portion, a second small-diameter portion, and a magnetism blocking portion having a wall thickness less than that of the first small-diameter portion and the second small-diameter portion. When a magnetic circuit is generated by energizing the coil, a magnetic flux passing through the first small-diameter portion passes through the second small-diameter portion via an end face of the movable core and generates a magnetic attractive force inclining with respect to a center axis. Therefore, the movable core is moved to the stator core by the magnetic attractive force adding a magnetic attractive force generated by a magnetic circuit.

Abstract: A solenoid actuator (1) attached to hydraulic equipment comprises a shaft (5) connected to the hydraulic equipment, a plunger (4) fixed to the shaft (5), a coil (12) which magnetically drives the plunger (4), and a first bearing (7) and a second bearing (8) supporting the shaft (5) on either sides of the plunger (4). A plunger front chamber (74) is formed between the first bearing (7) and the plunger (4), and a plunger rear chamber (75) is formed between the plunger (4) and the second bearing (8). By providing a plunger exterior oil passage (63) on the outside of the plunger (4) to connect the plunger front chamber (74) to the plunger rear chamber (75), working oil flows through the plunger exterior oil passage (63) every time the plunger (4) strokes, thereby preventing a deposit of contaminant on the plunger (4) without increasing a stroke resistance of the plunger (4).
