SOLENOID VALVE

PROBLEM TO BE SOLVED: To reduce the number of ports and the setting space of an auxiliary block to set solenoid valves. SOLUTION: The first solenoid valve 21 and the second solenoid valve 22 are heaped and installed on an auxiliary block 23. To the auxiliary block 23, a feeding port, an output port, an exhaust port and the like are formed. The solenoid valve 21 is composed of a solenoid 26 and the first valve main body 27, while the solenoid valve 22 is composed of a solenoid 26 and the second valve main body 28. To the valve main bodies 27 and 28, a feeding passage 62 to feed the pressure fluid from the feeding port to the first valve chest 51, passages 55 and 56 to lead the fluid from the valve chest 51 to the second valve chest 52, and an exhaust passage to exhaust the fluid from the valve chest 52 to the exhaust port are provided, and output passages 64 and 65, are provided at different positions respectively. To the valve main body 28, communication passages 66 and 67 to communicate the feeding passages 62 each other, and the exhaust passages 63 each other, and a communication passage 68 to communicate the output passage 64 of the valve main body 27 to the output port, are provided.
