Abstract
In a d.c. solenoid in which a thermistor having a positive temperature coefficient is connected in series with a main coil, a subcoil is connected in parallel with the series connection of the main coil and the thermistor, so that a large magnetic force can be produced at the solenoid energization starting time, and generation of heat from the thermistor can be suppressed to prevent burn-out of the main coil due to continuous current supply. Both the main coil and the subcoil, when energized alone, are capable of actuating the solenoid. The d.c. solenoid is applied to a valve in a vaporized fuel absorption system.
