- the first straight bar 220 is drawn out of the housing 100, and Some sections of the two straight bars 230 are inserted into the housing 100.
- the fluid filled in the first formation space 142 is introduced into the fluid transfer hole 400, the fluid contact block 210 does not reach the point where the fluid transfer groove 500 of the connection pipe 130 is located.
- the other end of the fluid transfer hole 400 is blocked as the fluid contact block 210 is in close contact with the inner surface of the connection pipe, so that the fluid is filled in the fluid transfer hole 400.
- the end of the fluid transfer hole 400 located at the circumferential surface of the fluid contact block 210 is the fluid transfer groove. Open in the 500, and the fluid in the first forming space 142 flows into the second forming space 144 through the fluid transfer hole 400, and at some point the first forming space 142 The pressure in the second forming space 144 is in the same state.
- the fluid contact block 210 and the second contact space 210 located in the second forming space 144 are formed. Since the cross-sectional area of the one straight bar 220 is wider than a point located in the first forming space 142, the entire working shaft including the fluid contact block 210 is moved to the first forming space 142 again.
- the fluid in the second forming space 144 flows through the first fluid discharge hole 234 of the first straight bar 220 to the fluid recovery path 232 and the fluid discharge path. It moves along 126 and is discharged to the outside.
- FIG. 15 is a view showing another modified example in which the other end of the fluid recovery passage 232 passes through the end of the first straight bar 220 without forming the fluid discharge passage 126 in the housing 100. As it is formed so that, in the process of discharging the fluid, the fluid introduced into the fluid recovery channel 232 is immediately discharged to the outside through the fluid recovery channel.
- the fluid recovery path serves as the fluid discharge path 126.
- first buffer member 310 and the second buffer member 320 may be installed in the embodiments of FIGS. 12 to 15.
- the diameter reducing groove of the first straight bar may be omitted, and the overall diameter of the first straight bar may be made smaller than that of the second straight bar, thereby increasing the cross-sectional area in the first forming space.
- FIG. 16 and 17 are views showing a modified example of the second buffering member 320, unlike the embodiment of FIG. 11 in which the second buffering member 320 is directly connected to the end screw 240 of the operating shaft 200.
- the second buffer member 320 is positioned directly in front of the connection point in the state in which the screw unit 240 is connected and fixed to the external object, and thus the buffer is buffered by the buffer unit during the front and rear movement of the housing 100.
- the second buffering member 320 is simply exposed to the outside, or as shown in FIG. 17, a separate cover 10 is disposed around and facing the second buffering member 320 of the operating shaft 200.
- a separate cover 10 is disposed around and facing the second buffering member 320 of the operating shaft 200.
- This modification of the shock absorbing member is applicable to all the embodiments described above irrespective of the internal structure of the housing.
- both ends of the operating shaft 200 basically protrude to the outside of the housing 100 so that the vibration can be output through both ends of the operating shaft 200, thereby increasing the vibration generating efficiency as compared with the conventional method.
- the biggest feature is that it enables stable installation.
- the diameter of one side of the operating shaft 200 may be artificially thickened or artificially reduced by cutting, such as the diameter of both sections
- the difference may be that the whole diameter of one side of the operating shaft 200 may be thicker or smaller, or only the diameter of the section in the pressure forming section 140 may be thicker or smaller.
- the movable shaft inside the housing can apply vibration to the external object connected to the movable shaft while repeatedly moving back and forth by the fluid pressure, in particular so that the vibration output by the movable shaft can be made simultaneously in both directions of the housing
