To provide an electromagnetic pump with a thermal shut-off valve for preventing burning and deformed deterioration due to high temperatures, leakage of a fuel and expansion of fire accident.
In the electromagnetic pump for supplying the fuel by a liquid fuel incinerator, a valve seat, a receiving seat, a valve element, a spring and a spring seat are arranged in an intake passage of the electromagnetic pump. The receiving seat is formed of a thermoplastic resin and the valve element is pressed and energized to the receiving seat by the spring to seat and the valve seat is arranged at a downstream side. The electromagnetic pump is overheated from outside and when it reaches a predetermined temperature, the receiving seat is buckled by thermal softening, the valve element is moved through the receiving seat by the spring and shuts a flow passage by contacting with the valve seat.
