<p>A piston type power machine comprises a cylinder body (1) and a piston component (2) mounted in the cylinder body (1). Both ends of the piston component (2) are symmetrically provided with pistons (21) which are fixed on the respective ends of a connecting-rod (22); the connecting-rod (22) is provided with racks (23) arranged in the moving direction of the pistons and gears (24) engaged with the racks (23); and the gears (24) are fixed on a power output shaft (26) of the power machine by a one-way bearing (25). The power machine increases energy utilization rate, improves the cylinder volume density and power density, and facilitates manufacturing.</p> |
