活塞式气动马达的工作原理

主要由：马达壳体、连杆、曲轴、活塞、气缸、配气阀等组成。压缩空气进入配气阀芯使其转动，同时借配气阀芯转动，将压缩空气依次分别送入周围各气缸中，由于气缸内压缩空气的膨胀，从而推动活塞连杆和曲轴转动，当活塞被推至“下死点”时，配气阀芯同进也转至第一排气位置。经膨胀后的气体即自行从气缸经过阀的排气孔道直接排出。同时活塞缸内的剩余气体全部自配气阀芯分配阀的排气孔道排出，经过这样往复循环作用，就能使曲轴不断旋转。其功主要来自于气体膨胀功。

Piston pneumatic motor principle of work

Mainly consists of: motor shell, connecting rod, crankshaft, piston and cylinder, valve, etc. Compressed air into the air with its core, with rotation by air, will be the core of compressed air into the surrounding air cylinder respectively, due to the expansion of compressed air in cylinder, so as to promote the piston and crankshaft connecting, when the piston is pushed down dead spots ", with the core with air exhaust to first place. The expansion of the gas automatically from the exhaust duct cylinder valve directly after discharge. While the residual gas piston cylinder valve core with all the vent duct, corundum, through such reciprocating cycle can make the crankshaft

constantly rotating. Its function mainly comes from the gas expanding power.
