Claims

[Scope of utility model registration request]

A power supply unit 9 and an oscillation circuit unit 1 that oscillates a predetermined frequency Fo.
0, a frequency divider 11 connected to the next stage of the oscillation circuit section 10, and a frequency F oscillated by the oscillation circuit section 10.
The battery is discharged by the discharge command signal A, which is transmitted every cycle determined by the frequency division value of the frequency divider 11, and the charging time is determined by the sizes of the capacitor and resistor. An electronic timer 7 comprising a charging type time constant circuit 13 and an electronic relay 14 that closes a normally open contact for the charging time of the capacitor in the charging type time constant circuit 13 is arranged on a board 15 to control compressed air. of storage tank 4,
The drain in the compressed air storage tank 4 is discharged every time the normally open contact of the electronic relay 14 is closed by controlling the opening and closing of a solenoid valve 6 disposed at the drain discharge port 5. Automatic drain discharge device.
