The gas chamber 500a is connected to the backflow prevention type The fluid of the outside air is newly introduced again through the inflow valve 512.

When the pressure of the compressed fluid generated in the pressure chamber 102 is increased so that the external force for the downward movement of the shift rod 500 is removed within the set pressure range of the pressure adjusting means 210, The piston 400 is caused to ascend by the action of the pressurized fluid pressurized in the pressure chamber 102 while the pump chamber 101 is actuated by the pressure pump operation in which the volume is contracted again according to the upward movement of the piston 400 The compressed fluid generated in the pump chamber 101 is discharged to the pressure chamber 102 through the discharge valve unit 440. As a result, 102 are raised to a set pressure, and the position of the shift rod 500 also rises to a set maximum height. That is, the piston 400 gradually reaches a covering member to be mounted on the side portion of the shift cylinder, and moves to a predetermined height range.

When the reciprocating operation of the shift rod 500 is repeatedly performed, a compressed fluid is continuously generated in the pump chamber 101 and the compressed fluid is continuously supplied to the pressure chamber 102 through the discharge valve means 440 The overpressure is discharged to the outside through the pressure regulating means 210, so that the pressure chamber 102 is discharged to the outside through the seat pressure The appropriate pressure is maintained in accordance with the range of the set external force exerted on the valve.

3, when the rotational force acts on the shift rod 500, the piston 400 is fixed to the piston 400, as shown in FIG. 3 of the accompanying drawings. The center of the shift rod 500 fastened to the shift rod 500 is eccentrically disposed at a predetermined distance e from the center of the piston 400 and the shift cylinder 100 to prevent the shift rod 500 from rotating.

24, the pressure regulating means 210 is controlled to adjust the pressure regulating means 210 so that the pressurized fluid in the pressure chamber 102 is freely discharged to the outside, as described above, The compression fluid pressurized in the pressure chamber 102 during the downward compression operation of the piston 400 is discharged to the outside through the pressure regulating means 210, Since the suction operation of expanding the volume of the pressure chamber 102 in accordance with the upward movement of the piston 400 is performed during the upward drawing operation of the piston 400, The fluid in the outside air is sucked into the pressure chamber 102 through the control valve 440 and the control valve unit 450 so that the pump chamber 102 is opened through the discharge valve unit 440 during the suction operation of the pressure chamber 102, 101 is sucked in And sucks the fluid stored in the gas chamber 500a through the control valve unit 450. [

As described above, when the shift rod 500 is downwardly compressed and operated in the state where the fluid in the outside air is sucked and stored in the pressure chamber 102, the compressed fluid generated in the pressure chamber 102 is compressed A series of air pumping operations externally discharged through the adjusting means 210 is performed and utilized as the air pump of the present invention.

In the meantime, when the shift rod 500 is lifted up to a high height, when an external force in the range set in the shift rod 500 acts, the discharge valve device 440 The compressed fluid in the pressure chamber 102 is shut off by the control valve unit 450 and the control valve unit 450 and the compressed fluid is discharged from the pressure chamber 102 in the set pressure adjustment range of the pressure control unit 210. [ This state of cutoff is established so that the pressurized fluid in the pressure chamber 102 is pressurized by the pressurized fluid proportional to the external force acting on the shift rod 500 while the piston 400 is lifted upward .

When the adjusting lever 621, which is illustrated in FIG. 25, is operated downward to adjust the height of the height adjusting device to a low level, the adjusting lever 621 rotates counterclockwise about the fixing shaft 630 The control rod 601 is lowered downwardly and the restrictive opening of the control valve 450 is performed so that the high-pressure compressed fluid filled in the pressure chamber 102 flows into the gas chamber 601. [ The piston 400 is lowered to the lower side while being discharged to the cylinder 500a.

When the high-pressure compressed fluid filled in the pressure chamber 102 is discharged to the gas chamber 500a through the opening of the control valve 450 as described above, the gas chamber 500a includes: The reverse flow preventing type inflow valve 512 of the compartment member disposed above the shift rod 500 blocks the external discharge of the compressed fluid and pressurizes the high pressure of the compressed fluid discharged from the pressure chamber 102 Pressure compressed fluid filled in the gas chamber 500a is also filled into the pump chamber 101 through the suction valve unit 460. As a result,

When the control lever 621 is turned to the original position to shut down the control valve unit 450 in order to stop the downward movement of the shift rod 500, The compression fluid discharged to the compression chamber 500a is shut off and the downward movement of the piston 400 and the shift rod 500 is stopped and the compressed fluid in the pressure chamber 102 is compressed by the shift And remains pressurized to a high compressed fluid state proportional to the external force acting on the rod 500.

In this state, when the external force acting on the shift rod 500 is removed, the downward compression action of the piston 400 is eliminated, so that the pressurized fluid in the pressure chamber 102 is reduced to a low pressure The high pressure fluid filled in the gas chamber 500a flows into the pressure chamber 102 through the regulating valve device 450 and the high pressure The compressed fluid of the high pressure fluid is discharged to the pressure chamber 102 through the discharge valve means 440 so that the high pressure fluid is filled again in the pressure chamber 102. Thus, The operation of the pressurizing chamber 102 is increased to a predetermined height by the action of the compression fluid.
