The reciprocating action further drives the interlocking shaft 16 to perform a substantial reciprocating action in the sub-body 30.

The composition and function of the above embodiment are described in detail as follows: Referring to Figures 1 and 2, during the creation operation, the pump pressurized high pressure gas is introduced from the air inlet 201, and the valve body 23 is initially received by the valve body 23 The elastic member 25 is abutted against the partition plate 21, and the third space 223 makes the air inlet 201 and the first communication hole 204 conductive, and the air inlet 201 and the second communication hole 205 are non-conductive. The high pressure gas enters the left air pressure chamber 12 through the first communication hole 204 through the third communication hole 212. At this time, the left air pressure chamber 12 is pressurized by the high pressure gas to move the piston 11 toward the auxiliary body 30. At the same time, the air in the right air pressure chamber 13 is pressed and enters the fourth space 224 of the air valve chamber 22 through the second communication hole 205 through the second communication hole 205, and is further discharged to the outside air by the second ventilation hole 203. Thereby, when the right pneumatic chamber 13 is compressed by the piston 11, the air can be discharged without hindering the movement of the piston 11.

Referring to FIGS. 3 to 4, when the piston 11 continues to move to the right until it interferes with the sub-body 30, the ring groove 15 of the main shaft 14 is located in the left air chamber 12, the through hole 211 of the partition 21, and Between the through holes 24 of the valve body 23 and the first space 221 of the left pneumatic chamber 12 and the valve chamber 22, at which time high pressure gas enters the first communication hole 204 through the third communication hole 212. After the left air pressure chamber 12, the first space 221 of the air valve chamber 22 is input between the ring groove 15 and the through hole 211 and leads to the through hole 24, because the leakage preventing ring 141 of the main shaft 14 is closed. One end of the hole 24, and the partition plate 21 is provided with a groove 213 corresponding to the valve body 23 to form a gap, and the circular diameter of the first convex ring 231 is set larger than the second and third convex rings 232, 233 The circular diameter, using the principle of F (force) = P (pressure) * A (forced area), allows high pressure gas to enter from the gap of the groove 213 and form a larger end face of the first convex ring 231 of the valve body 23. The high pressure thrust causes the valve body 23 to be displaced to the left against the elastic force of the elastic member 25, and the third space 223 is formed to electrically connect the air inlet 201 and the second communication hole 205, and the air inlet 201 and the air inlet 201 are The first communication hole 204 is non-conducting; at this time, the air inlet hole 201 stops inputting high-pressure gas into the first space 221 of the valve chamber 22, and then the high-pressure gas passes through the second communication hole 205 through the fourth communication hole. 301 enters the right air pressure chamber 13 , and the right air pressure chamber 13 is pressurized by the high pressure gas to move the piston 11 toward the main seat body 20 , so that the ring groove 15 of the main shaft 14 is separated from the partition plate 21 . The hole 211 instantaneously closes the through hole 211, causing the left air pressure chamber 12 to be disconnected from the first space 221 of the air valve chamber 22, forming the first space 221 in an extremely high pressure state, and allowing the valve body 23 to continue. Keeping against the elastic force of the elastic member 25 against the closing plate 26; at the same time, the air in the left air pressure chamber 12 is pressed and enters the gas through the first communication hole 204 through the third communication hole 212. The second space 222 of the valve chamber 22 is further discharged to the outside air by the first vent hole 202, whereby the left air pressure chamber 12 is compressed by the piston 11 so that air can be discharged without hindering the movement of the piston 11.

Referring to FIGS. 5-6, when the piston 11 continues to move until it abuts against the partition 21, the leakage preventing ring 141 of the main shaft 14 leads to the enlarged portion 241 of the through hole 24 without being in the hole. The wall contact forms an unclosed state, and the high pressure gas is released from the first space 221 instantaneously, and the high pressure gas is discharged from the second vent hole 203 to the outside air through the vent hole 234, and the valve body 23 is released after being released. No longer having the ability to resist the elastic member 25, and then being supported and moved against the partition plate 21, and returned to the initial state; thus, the cyclical switching is repeated, and the interlocking shaft 16 can be in the auxiliary base body 30. Continuous reciprocating motion produces mechanical energy and can be converted into other energy effects for different purposes.

However, the above-mentioned ones are only preferred embodiments of the present invention, and are not intended to limit the features of the present creation. The re-creation of the technical means and creation principles related to the creation is still the creative equivalent of the creation. .

In summary, the structure of this creation does have excellent practicality and enhanced efficiency. It is in line with the provisions of the Patent Law, and it is submitted in accordance with the law.
