Composition and working principle of piston air motor

It is mainly composed of: motor housing, connecting rod, crankshaft, piston, cylinder, distribution valve, etc.

Air motor working principle: compressed air into the distribution valve core to make it rotate, while borrowing the gas distribution valve core rotation, the compressed air in turn into the surrounding cylinders, due to the expansion of compressed air in the cylinder, thereby pushing the piston connecting rod and crankshaft rotation, when the piston is pushed to the "lower dead center", the distribution valve core also turns to the first exhaust position. The expanded gas is discharged directly from the exhaust channel of the cylinder through the valve. At the same time, the remaining gas in the piston cylinder is all discharged from the exhaust orifice of the gas distribution valve spool distribution valve, and after such reciprocating cycle, the crankshaft can be continuously rotated. Its work mainly comes from the gas expansion work.
