PISTON DEVICE AND PRESSURE REGULATOR USING SAME

摘要

Disclosed is a piston device, comprising a piston body (220) and a baffle plate (230) of which the surface is provided with openings, wherein the baffle plate (230) is arranged in the piston body (220) and divides the piston body (220) into an upper first area C and a lower second area B. Further disclosed is a pressure regulator which comprises the piston device. The piston device is beneficial for improving the stress balance of the first area and the second area, thereby improving the stability of the overall system.
