Referring to Fig. 4, the fluid pressure piston 40 201033466 has the first pumping portion 40a and the second pumping portion 40b. The first pumping portion 4A is inserted into the first fluid pressure chamber 46, and the second pumping portion 40b is formed at one side of the first pumping portion 40a and inserted into the second fluid pressure chamber 33. . The second I-feed portion 4〇b has a uniform through hole 42 that is configured to communicate with the first suction hole 34a in a state in which the fluid pressure piston 40 moves rearward. The low pressure cylinder 44 is in the inner first chamber. The upper end of the 46 has a piston hole φ 45 and has a through hole 47 in a top cymbal, the second pumping portion 40b passes through and contacts the piston hole 45, and the through hole 47 is used to connect the first The suction hole 3 is known to the first discharge hole 36a. The through holes 47 are disposed such that the center lines of the holes are mutually parented to evenly connect the first pressure release holes 39a of the rear side. A gasket groove 48 is formed in a lower portion of the low pressure cylinder 44, and a gasket 49 is inserted into the collar groove 48 to prevent leakage of the fluid pressure piston 4'' by the first chamber 46. The low pressure cylinder 44 is preferably combined with the cylinder bore 32 by a screw. Specifically, the present invention is characterized in that the first fluid pressure chamber pumped by the first pumping portion 4 is configured to have a second fluid pressure chamber 33 that is sent by the second fruit delivery portion. The cross-sectional area is small, and thus a discharge fluid pressure is supplied as a double low/high pressure. In other words, the second portion of the fluid pressure piston is formed to have a smaller diameter (i.e., a sectional area) than the first pumping portion 40a. Thereby, the fluid pressure of the second fluid pressure chamber 33 is discharged higher than the fluid pressure of the first fluid pressure chamber 46. The first and second joints 5A and 50b are respectively combined with the first and second 9201033466 suction holes 34a and 34b, and the inner ball 53 is operated by up/down, and the first and second joints 50a and 50b allows a fluid to flow in only one direction. A filter member is disposed in the inlet 52 of the first and second joints 50a and 50b and prevents entry of foreign matter. The first and second check valves 56a and 56b are coupled to the first and second discharge holes 36a and 36b. Since the inner ball 57 closes the discharge holes 36a and 36b by downward contact with an elastic unit, the first and second check valves 56a and 56b allow a fluid to flow only in a upward direction in which a fluid pressure is discharged. Further, the present invention is characterized in that the first and second pressure release valves 7a and 7B are disposed in the respective first and second pressure release holes 39a and 39b, and the first and second pressure release holes 39a and 39b communicates with one side of the first fluid pressure chamber 46 and the second fluid pressure chamber 33. The first and second pressure relief valves 70a and 70b are general valves for controlling the discharge pressure of the low/high pressure supplied to the first and second fluid pressure chambers 46 and 33. The pressure relief valves 70a and 70b are each wrapped in a ball of an internal passage, an elastic unit in contact with the ball, and a control unit. Thus, the pressure relief valves 70a and 70b can appropriately control the discharge pressure of a fluid pressure. A release hole 37 is disposed between the first and second discharge holes 363 and 361) and communicates with the second discharge hole 36b through a connection passage 38. A release valve 28 is coupled to the release port 37, and the release valve 28 is pressurized and operated by the other portion of the upper operating unit 25, thereby discharging and releasing a fluid pressure. Figure 5 is a plan view of a port block taken along the line of Figure 2. 201033466 The port block 60 has first and second ports 62a and 62b, each of which is formed and connected to the first and second discharge holes 36a and 36b. The first and second ports 62a and 62b are connected to the discharge hole 65 through the one side connecting passage 64. A fluid pressure pipe 1〇1 is connected to the discharge hole 65 and supplies a fluid pressure to the fluid pressure operating unit. 25. In addition, although not shown in the drawings, a pressure gauge for measuring low/high pressure is disposed in the port block 6 and the flow meter is used for recovery of the fluid circulated by the fluid pressure operation unit tl25. The unit, and the holding unit are disposed in the container 10. The operation of the air booster pump of the present configuration having the foregoing configuration is as follows. Fig. 6 is a cross-sectional view showing the operational state of one of the air pressurized fruits of the present invention. Referring to the drawing, if the operating unit (ie, the operating pedal (10) is pressurized, then supply-air and at the same time the pneumatic cylinder 2〇 automatically reciprocates, when the fluid pressure piston 40 moves forward, pump the One of the fluid pressure chambers fluid 'and passes through the upper discharge hole and the through σ. At this time, in the lion reading (10), when the σ is blocked, the balls 53 fall due to the fluid pressure and are in the check valve 56a. And the pressure reduction of the borrowing body of the ball 57 in 56b becomes the upward opening state. Conversely, if the fluid pressure piston is operated oppositely, the air piston moves backward, as shown in Fig. 2, the discharge hole is The check valves are blocked and simultaneously 'when the population is opened, the ball of the joint moves up due to the suction of the body and the fluid is sucked by the first and second fluid pressure chambers. 201033466 Accordingly, the present invention The air booster pump repeatedly performs the pumping stroke according to the forward/backward movement of the fluid pressure piston, thereby achieving continuous pumping. Not only a double discharge force generated by one pumping is generated, but also can be simultaneously supplied. Low/high Fluid pressure. As described above, the air booster pump of the present invention utilizes a fluid pressure chamber and fluid pressure of a dual structure when a fluid pressure is equally supplied by a conventional pump to generate a fluid pressure. The piston double generates the fluid pressure, thereby providing an effect that substantially increases fluid pressure and significantly improves pump performance. Further, because a dual fluid pressure generated by the first and second fluid pressure chambers has a Is the difference of the discharge pressure of a low pressure/high pressure, so the present invention has an appropriate selection and application of a difference in fluid pressure (ie, an operating force) provided by the pump according to the use of the fluid pressure operating unit and effectively The advantage of using this difference. Further, the present invention includes various pressure relief valves in the first and second fluid pressure chambers and thus has a fluid pressure that can independently and appropriately control a low or high pressure.
