Abstract

A piston device and a pressure regulator including the piston device. The piston device includes a piston body and a baffle plate having a surface provided with openings. The baffle plate is arranged in the piston body and divides the piston body into an upper first area and a lower second area. The piston device beneficially improves the stress balance of the first area and the second area, thereby improving the stability of the overall system.
