通孔５２４より流出する。 The pneumatic cylinder 3 and the hydraulic cylinder 24 are fastened to the valve stand 5 by bolts 31. On both sides of the valve stand 5, there are an L-shaped air inlet hole 53 and an air outlet hole 5 that communicate with the pneumatic cylinder 3, respectively.
2, and the air inlet 53 has a check valve 531, a spring 532, and a hollow bolt 533, allowing air to flow in but preventing air from flowing out, thereby controlling a single flow of air. There is also a semicircular check valve 521 and a spring 522 inside the vent hole 52, and a hollow bolt 523 is screwed into the thread inside the vent hole 52 to push one end of the spring 522. If the bolt 523 is tightened, spring 522
comes to press against the check valve 521 and the air outlet 52, and the air inside the pneumatic cylinder 3 is pressed, and when the air inside is pressed and exceeds the pressure of the spring 522, the high pressure air is simply released. The flow valve 521 is pushed open and the air flows out from the central through hole 524 of the bolt 523 via the air outlet hole 52.

のみが働いて単独にジヤツキの効果を発揮する。 The through hole in the center of the valve stand 5 is opened just so that the piston rod 44 can pass through, and
A packing 51 is provided around the bottom to allow movement of the piston rod 44 but to ensure an airtight seal. The air sucked into the air intake hole 53 by the compression of the piston 441 is compressed to the pressure set by the bolt 523, and from the air filling joint 525 screwed on the outside of the bolt 523, a hose 54 having a nozzle at the tip is connected. This allows air to be filled into an external air device. In addition, there is a pressure gauge 5 in the air outlet 52.
5, the pressure can be adjusted. If vent hole 5
If the bolt 523 is loosened to the maximum with the cylinder 2 open to the atmosphere, the air will automatically flow out without being compressed, and the pneumatic cylinder 3 will not compress air, but the hydraulic cylinder 24
The only thing that works is to exert the effect of jacking alone.

４が入り、更にその上に滑り止めスタンド２４１
及びもう一つのパツキング２４２を設けている。 The hydraulic cylinder 24 communicates with the oil pipe of the jack 2, and has a piston rod 4 in the opening at its upper end.
4 is inserted, and a non-slip stand 241 is placed on top of it.
And another packing 242 is provided.

中及び油圧シリンダ２４中での最低点と最高点の
間を移動して最高の圧縮効率が得られる。 There is another oil pipe at the bottom of the large hydraulic cylinder 21, which returns oil to the hydraulic cylinder 24 via the release valve 22. When the loosening valve 22 is loosened, the jack piston 2
3 is automatically lowered, the cylinder 24 does not generate oil pressure, and only the pneumatic cylinder 3 works to perform independent air filling. The upper piston 441 compresses air, and the lower piston 442 compresses the oil inside the hydraulic cylinder 24. The distance between the two pistons 441 and 442 is larger than the stroke of the pneumatic cylinder 3, and both the pistons 441 and 442 are connected to the pneumatic cylinder 3.
The highest compression efficiency is obtained by moving between the lowest and highest points in the middle and hydraulic cylinders 24.
