Abstract
PURPOSE: To reduce the ampere-turn of a solenoid, by powerfully attract a plunger by the attractive force caused between an attraction plate and an auxiliary yoke and that caused between the plunger and a pole core.
CONSTITUTION: When electricity is not applied to lead wires 15', a plunger 17 is moved leftward by a return spring 18 to shut off the opening of a negative pressure source passage 21'. When electricity is applied to the lead wires 15', the plunger 17 is attracted by an auxiliary yoke 19 and a pole core 14 so that the plunger is moved rightward and a valve 23 is caused by a spring 24 to shut off the opening of a passage 33 and open the negative pressure source passage 21'. According to this constitution, both attracted areas are made large to obtain a strong attractive force. For that reason, the ampere-turn of a solenoid can be reduced and the solenoid can be made compact and light.
