Screw hole 14 facing hole 4c
are provided for each. In addition, each flange portion 1
2 is provided with a plurality of small holes 15 along the longitudinal direction, and a notch 16 is provided below the screw hole 14 through which the plug body 4b is inserted.

The chassis 20 includes a horizontally long first mounting board 21, a support plate 22 extending downward from one longitudinal end of the first mounting board 21, and a bottom surface of the first mounting board 21 on the one end side. The second mounting board 23 is attached to the first mounting board 2.
1, an elliptical through hole 24 through which the suction side joint portion 3b of each electromagnetic valve 3 passes is provided in a portion facing each of the through holes 13, and a portion of the mounting bracket 10 facing each small hole 15 is provided with an elliptical through hole 24 through which the suction side joint portion 3b of each solenoid valve 3 passes. The screw hole 25 is inserted into the mounting bracket 1.
A long hole 26 through which the plug body 4b is inserted is provided at a portion facing each notch 16 of the plug body 4b. Further, a cord insertion hole 27 is provided near one end of the first mounting board 21. Furthermore, the electromagnetic pump 30 is mounted on the second mounting board 23.
An insertion hole 28 is provided for mounting.

Next, a method for assembling the pressure spray combustion apparatus according to this embodiment will be explained. First, as shown in Figure 1,
An O-ring 6 is attached to the discharge side joint 3a of each solenoid valve 3.
0, and furthermore, each discharge side discharge side joint part 3a
are inserted into each through hole 13 of the mounting fitting 10. On the other hand, the suction side joint portions 3b of each electromagnetic valve 3 are inserted into each through hole 24 of the first mounting board 21 of the chassis 20. In addition, the chassis 20
Fit the protective ring 61 into the cord insertion hole 27 of
The electrical cord 3c of each solenoid valve 3 is connected to the protective ring 6.
1 and lead it out of the chassis 20.
Then, each small hole 15 of the mounting fitting 10 is made to correspond to the screw hole 25 of the chassis 20, and the screw 6
At step 2, the mounting fitting 10 and the chassis 20 are fastened. As a result, each electromagnetic valve 3 is fixed between the mounting fitting 10 and the chassis 20.

Further, as shown in FIG. 3, the lower end of each nozzle adapter 1 is connected to the discharge side joint 3a of each solenoid valve 3 via an O-ring 63, and the upper end of each nozzle adapter 1 is connected to each other through an O-ring 63. Connect nozzle 2. Further, the spark plug 4 is inserted through the elongated hole 26 of the chassis 20 and the notch 16 of the mounting fitting 10, and the plug body 4b is further inserted.
Insert the screw 64 into the mounting hole 4c of the
into the screw hole 14. As a result, each spark plug 4 is attached to the mounting fitting 10. Note that the electromagnetic pump 30 to which the oil filter 40 is attached is attached to the second mounting board 2.
It is attached to the mounting board 23 with screws 65 inserted through the insertion holes 28 of No. 3.

Then, as shown in FIG. 4, the branching device 5
The inflow pipe 51 of No. 0 is connected to the discharge port 31 of the electromagnetic pump 30 via a nut 51a, and each branch pipe 5
2 is connected to the suction side joint portion 3b of each electromagnetic valve 3 via a nut 52a. This results in
