FLUID-OPERATED BRAKE ACTUATOR WITH CHECK VALVE

摘要

A fluid-operated brake actuator (10) having a check valve (90) in the spring chamber (62) to equalize the pressure on opposite sides of an operating movable diaphragm (52). The check valve being double redundant and tamper resistant and comprising a tubular body (92) having a first one-way valve (94) disposed and one end of the tubular body and a second one-way valve (96) disposed at an opposite end of the tubular body. A support plate (98) is mounted to the tubular body to support the second valve and prevents the easy removal of the check valve from the brake actuator.
