Abstract: An air valve assembly housing, in particular an air valve assembly, is for an air valve assembly of a commercial vehicle air suspension system. The air valve assembly housing includes an air exhaust chamber and an actuator chamber configured to accommodate a pneumatic actuator. The pneumatic actuator has a valve body that is configured to move between a closed position and an open position. The air valve assembly housing includes a fluid passageway that extends from the actuator chamber to the air exhaust chamber such that the actuator chamber and the air exhaust chamber are in fluid communication at least when the valve body is in the open position. A number of radially extending protrusions partially obstruct the fluid passageway.
