Document Type and Number:
Japanese Patent JP3005494
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To securely interrupt a gas flow passage and hence improve safety by driving an opening valve control part for its opening shifting operation timing through an actuator where an instrument cock and a solenoid safety valve are interlocked with a single motor, and opening the solenoid safety valve before opening the instrument cock by supplying power to an electromagnet. SOLUTION: A single motor M for driving functional parts such as a solenoid safety valve MV, etc., uses a geared motor, etc., and each functional part is driven through an actuator K interlocked with the motor M changing each tinning. More specifically, a cam is used as the actuator K which cam is fixed to an output shaft of the motor M and is intermittently rotated by a predetermined angle to drive each functional part changing timing. The solenoid safety valve MV is mounted upstream a gas supply passage 12, and a safety valve V5 energyzed by a stripe 13 in the direction of closing is opened, attracted, and held with a magnet 14, and as power supply to the electromagnet 14 is stopped, the safety valve V5 is automatically closed.
