タンク２１ａ，２１ｂ，２１ｃ内の圧力すなわち
配管３７内の圧力は、低いので、圧力スイツチ３
１は閉じている。 Before use, there is no waste oil in the waste oil display container 3, so the switch 39 is open, and the pressure in the oil tanks 21a, 21b, 21c, that is, the pressure in the pipe 37, is low, so the pressure switch 3 is open.
1 is closed.

On the other hand, the a contact R 1 ' of the circuit to the motor 29 and the circuit to the valves 25 and 26 is closed, the motor 29 and the gas pump 28 are rotated, and the valve 25 is connected to the intake atmosphere communication pipe 4.
0, the valve 26 and the new oil tank 21a,
It communicates with piping 37 to 21b and 21c.

The air sucked in from the tank is sent into the new oil tank 2.
The insides of 1a, 21b, and 21c are pressurized. Then, when the inside of the tanks 21a, 21b, 21c reaches a certain level or higher, the pressure switch 31 opens and the pump motor 2
9 is stopped and valves 25 and 26 are closed.

る。 Next, to drain oil from the oil pan of a car, select one of the nozzles 16, 16', 16'', 16 that matches the insertion opening of the oil pan, for example 16, and connect it to the hose 32 via the coupling 19. When this nozzle 16 is inserted into the oil pan and the oil drain switch 7 is closed, the b contact R 1 ',
Since R 3 ′ and R 4 ′ are closed, R 2 is energized and the b contact is closed.
R 2 ′ is opened, rotation to motor 29 and valves 25, 2
A contact R 2 ' of the circuit to 6 is closed, energizing the motor 29, which starts and rotates the gas pump 28.
The valve 25 communicates with a pipe 33 to the waste oil display container 3, and the valve 26 communicates with an atmosphere communication pipe 38 for exhaust.

９は停止し、弁２５，２６は閉じる。 Due to the movement of the gas pump 28, the air in the waste oil display container 3 is discharged to the atmosphere through the atmosphere communication pipe 38, creating a negative pressure, and the oil from the nozzle 16 is poured into the container and stored therein. After the oil has been drained, open switch 7 and motor 2
9 is stopped and valves 25 and 26 are closed.

イスプレイ容器３が空になればスイツチ３９が開
きリレーR5が消勢され弁２３が閉じる。 Next, in order to drain the oil from the waste oil display container 3 to the waste oil container 20, close the oil drain switch 8. Since there is oil in the container 3, since the switch 39 is closed, relay R5 is energized.
The a contact R 5 ' is closed and this is the self-retaining valve 23.
When energized, the valve opens and oil flows into the waste oil container 20 via the discharge pipe 22. When the waste oil display container 3 is empty, the switch 39 is opened, the relay R5 is deenergized, and the valve 23 is closed.
一方、新しいオイルを自動車のオイルパンに圧

量は表示計１１ａに表示される。 On the other hand, in order to pressurize new oil into the oil pan of an automobile, the nozzle valve 15a is inserted into the insertion opening of the oil pan and the valve 15a' is opened. Since the inside of the oil tank 21a is pressurized, oil flows out from the tank 21a into the oil supply pipe 30a, is measured by the flow meter 19a, and is discharged from the nozzle valve 15a, and the flow rate is displayed on the display meter 11a.
オイルタンク２１ａ内の圧力が一定以下の圧力
となると、前記したように、圧力スイツチ３１が
閉じ、リレーR1の働きにより、モーター２９が
回転し、弁２５，２６が切換わつて、オイルタン
ク２１ａ内が加圧される。 When the pressure inside the oil tank 21a becomes below a certain level, the pressure switch 31 closes as described above, the motor 29 rotates under the action of the relay R1 , the valves 25 and 26 are switched, and the oil tank 21a is turned off. The inside is pressurized.
他の油種をノズルバルブ１５ｂ，１５ｃから給
油する場合も同様である。 The same applies to the case where other types of oil are supplied from the nozzle valves 15b and 15c.
なお、配管２７内が一定圧力（２Kg／cm2）以上
になる圧力スイツチ３１が作動してタンクへの加
圧が停止するのでオイルタンク２１ａ，２１ｂ，
２１ｃが過加圧になることは防止される。 Note that when the pressure inside the piping 27 exceeds a certain pressure (2Kg/cm 2 ), the pressure switch 31 is activated and pressurization of the tank is stopped, so the oil tanks 21a, 21b,
21c is prevented from becoming overpressurized.

が終了したらスイツチ９を開く。 To replace the fluorocarbon gas in a car's air conditioner, set the fluorocarbon gas extraction coupling 17 and close the extraction switch 9 .
The relay R 3 is energized via R 2 ′, R 3 ′ , and R 4 ′, and the a contact R 3 ′ of the circuit to the motor 29 and the circuit to the valves 25 and 26 is closed, while the relays R 1 and R The a contact R 3 ' of the circuit to R 2 , R 3 and R 4 is opened. As a result, the valve 25 opens toward the coupling ring 17 via the hose 35, and the valve 25 opens toward the coupling ring 17 through the hose 35.
6 is open to the atmosphere communication pipe 38 side, and the motor 29
and the gas pump 28 rotates to couple the coupling 17
The fluorocarbon gas sucked up from the gas pump 28
and is released to the atmosphere via valve 26. When the extraction is completed, open switch 9.
