As the powerpiston moves to the right, the yellow linkage forces the loose-fitting, red piston(on the left half of the machine) to displace air to the cooler side of the engine.
当施力活塞到达右边时，黄色连杆会轻轻地带动红色“活塞”（在机器左边），使空气移到引擎较冷的一边。

Carrier later switched from pistonpower to the centrifugal chiller, which allowed much larger Spaces to be cooled.
Carrier后来把活塞动力改为离心式制冷机，可以冷却更大空间。

The crankshaft, regarded as the "backbone" of the engine, serves to change the reciprocating motion of the piston into rotary motion and handles the entire power output.
