As shown in FIG. 2, the automatic emulsion discharging device according to the present invention is provided in the middle of the air pipe 40 between the air compressor 50 and the air dryer 60. In addition, an air pipe 40 wound in a coil form before the automatic emulsion discharging device 1 may be provided to naturally cool the compressed air.

In the compressed air generating system of a commercial vehicle equipped with the automatic emulsion discharge device 1 as described above, first, the compressed air is generated by the air compressor 50. When generating the compressed air, the oil introduced into the air compressor 50 is mixed with the water in the air of the high temperature state to generate an oil solution, the automatic oil phase according to the present invention through the air pipe 40 together with the compressed air It flows into the liquid discharge device 1.

The mixer of the compressed air and the emulsion is introduced into the first zone I through the air compressor side air pipe, that is, the first pipe 40a, along the path indicated by the black arrow in FIG. The introduced compressed air and the emulsion mixture are separated into the compressed air and the emulsion through a filter 12 provided at the end of the first pipe 40a. The compressed air separated from the oily liquid flows into the compressed air chamber 11 of the first zone I and communicates with the compressed air chamber 11 along the path indicated by the white arrow in FIG. 3. After flowing into the first compressed air passage 30 of III), it flows to the air dryer 60 via the air dryer side air puff, that is, the second pipe 40b. Meanwhile, the oily liquid separated from the compressed air is stored in the oily liquid storage chamber 21 of the second zone provided below the first zone by the weight of the oily liquid along the path indicated by the hatched arrow in FIG. 3. .

As the above operation is repeated, as the emulsion in the emulsion storage chamber 21 rises, the emulsion measuring means 22 floating on the oil surface of the emulsion rises, and the emulsion measuring means 22 is used. When the annular metal plate 23 provided at the top of the terminal is connected to the positive and negative grounds, the power of the battery connected to the positive ground is transferred to the solenoid 35 of the third zone III through the metal plate 23 and the negative ground. Supplied.

The solenoid 35 supplied with electric power drives the valve rod 33 provided with the first valve 31 and the second valve 32 up and down, and thus the first valve 31 and the second valve 32. Activate First, when the valve rod 33 is driven downward, the first valve 31 presses the first stopper 36, compressing the first valve spring 38, thereby opening the first valve hole 42. Open. When the first valve hole 42 is opened, the compressed air stored in the air tanks 71 and 72 flows in through the air tank side air pipe 40c, that is, the third pipe, so that the first valve hole ( After 42, it flows into the compressed air chamber 11 of the first zone I via the second compressed air passage 43.

On the other hand, if the valve rod 33 is further driven downward after the first valve 31 is operated, the second valve 32 at a predetermined time difference from the operation of the first valve 31. Will work. When the second valve 32 is driven downward to press the second stopper 37, the second stopper 37 opens the second valve hole 44 while compressing the second valve spring 39.

In the above state, the compressed air introduced into the compressed air chamber 11 through the first valve hole 42 pressurizes the liquid level of the emulsion from above, and the second valve hole 44 is opened. As a result, the emulsion filled in the emulsion storage chamber 21 starts to be discharged, thereby enabling the automatic discharge of the emulsion.

After the emulsion is automatically discharged as described above, while the oil level of the emulsion storage chamber 21 is lowered, the oil measurement means 22 floating on the oil surface is also lowered, and the metal plate 23 is at the anode and cathode grounds. When the power supply from the battery is cut off, the solenoid 35 stops operating. Therefore, the first valve hole 42 and the first valve hole 42 and the second valve spring 39 are stopped by the elastic restoring force. The two valve holes 44 are closed by the first stopper 36 and the second stopper 38, respectively.

As described above, according to the automatic emulsion discharging device 1 according to the present invention, it is possible to prevent the emulsion from entering into the air dryer 60 and to decrease the function, thereby improving the braking performance of the vehicle. Unlike the conventionally had to be drained frequently, since the oil can be discharged automatically, it is possible to implement a convenient compressed air system.

Although the preferred embodiments of the present invention have been described above, the scope of the present invention is not limited to such specific embodiments, and those skilled in the art are appropriately within the scope described in the claims of the present invention. Changes will be possible.
