摘要： A brake system and a valve device for a brake system are provided which provide at least partial front brake actuation in the event of a failure in the front brake pneumatic supply circuit. The valve device may be configured as a biased orifice double check valve which permits compressed air flow from the front brake pneumatic supply circuit to a front brake actuator during normal brake operation, but in the event of lack of sufficient front brake pneumatic pressure permits compressed air to be supplied to the front brake actuator from a rear brake pneumatic supply circuit, as well as permitting compressed air in the front brake actuator to be ventilated back through the rear brake pneumatic supply circuit when the brake is released.

摘要： A brake actuator comprises a housing having an end wall and a pushrod projecting through an opening in the end wall and terminating at a movable plate in the housing. A spring is enclosed in the housing and surrounds the pushrod. At least one unitary resilient member is disposed on the push rod proximate to the end wall and partially extends through the opening for centering the spring around an axis of the pushrod and restricting contamination into the housing. The unitary resilient member comprises a central aperture and an annular flange surrounding the central aperture. At least one section of a collar radially outward from the annular flange has a thickness less than half of the annular flange thickness for constraining movement of the spring and the push rod in a radial direction.
