On the other hand, Patent Document 2 discloses a multiple solenoid valve having a plurality of solenoid valve mechanisms. Since this solenoid valve has a plurality of valve holes inside the housing, there is a problem that it is difficult to process each valve hole. Therefore, if the technique of the joint housing described above is applied to such a multiple solenoid valve, a plurality of valve holes should be processed with high accuracy.

And a notch 54d having the same shape as the protrusion is formed on the other leg 54b. The protrusion 54c and the notch 54d are connected to the notch 54 of the mounting base 54 of the adjacent socket 51. By sequentially fitting the notches 54d and the projections 54c, the plurality of sockets 51 are installed in a locked state.

However, a plurality of the sockets 51 may be integrally formed and used as they are. In the case of the illustrated triple solenoid valve 1A, three sockets 51 are integrally formed. In this case, the mounting base 54 is formed in a state where a plurality of mounting bases are integrally connected, and the protrusion 54c and the notch 54d are formed on the two leg portions 54a and 54b located at both ends.
Alternatively, a plurality of sockets 51 can be integrally formed and separated individually or in a necessary number of consecutive states for use. In this case, the protrusion 54c and the notch 54d may not be formed.

  In the above-described example, each socket 51 is connected to the power supply connector 10 by the lead wire 55. However, as shown in FIG. It can also be configured to be installed in the hollow portion 41 of the housing 20 and connect each socket 51 to the power feeding connector 10 via the substrate 57. In this case, connecting connectors 58 are attached to both ends of the substrate 57, and the connectors 58 are sequentially electrically connected to the connecting connectors of the substrates built in the adjacent solenoid valves 1A and 1B, the air supply / exhaust block 2 and the like. It is desirable to configure as follows. Further, when the socket 51 is attached to the substrate 57 in this way, the attachment base 54 as shown in FIG. 8 can be omitted.

The 24B pressure fluid is discharged to the outside.

  When the energization of the pilot valve 23 is cut off, the second pressure chamber 38 is opened to the outside and the pilot fluid is discharged, so that the first pressure chamber 37 that is constantly acting on the pressure receiving surface 22a of the spool 22 The spool 22 is pushed by the action of the fluid pressure and moves to the second switching position on the opposite side. For this reason, the supply connecting hole P and the output second independent hole B communicate with each other so that the pressure fluid is output from the second output port 24B, and the output first independent hole A and the discharge are discharged. The first fluid connection hole EA communicates with the first output port 24A to discharge the pressure fluid to the outside.

  The plurality of pilot valves 23 are selectively operated individually, but the operation timing is arbitrary, and a plurality of pilot valves 23 can be operated simultaneously.

  The housing 20 of the electromagnetic valve 1A is formed by joining two housing members 20A and 20B by a method such as soldering. The two housing members 20A and 20B are provided with the end plate. 35 and each piston plate 43 are arranged so as to straddle both housing members and are fixed to both housing members, so that each of these plates 35 and 43 acts in a direction to separate both housing members.
