| 摘要 |
The present invention relates to a pneumatic engine and, more specifically, a motor machine capable of generating rotation movements by enabling a piston to perform rectilineal movements and rectilineal reciprocating movements with a fluid pressure by changing a cylinder of the motor machine in which the piston reciprocates due to explosion of a fuel for the rotation movements, into a single-acting or a double-acting pneumatic cylinder. An oil outlet uses a pneumatic cylinder having a larger area than an oil inlet. |
