CONSTITUTION: A piston type of a brake actuator applied with a pressure internal dual valve comprises a push rod(13) and a check valve(60). The push rod comprises a fluid hole(58) at the end part. The push rod connects a service chamber(12) to a piston chamber(11) when a vehicle brake is in operated. The push rod moves fluid to a case(10). The check valve is mounted inside the push rod. The check valve opens and closes the fluid hole by the pressure of compressed air. The check valve comprises a valve housing(61), a first valve body(62), and a second valve body(63). |
