| description | 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). |
