Abstract
A pneumatic ABS valve device for a pneumatic brake system of a vehicle comprises a check valve mechanism for enabling a supply air flow from a supply port to a delivery port and blocking an air flow in the reverse direction. The check valve mechanism comprises a quick release insert disposed in an insert chamber, the quick release insert being placeable in a basic position for providing a chamber passage in the insert chamber enabling the supply air flow. The quick release insert is displaceable by an air pressure difference from the basic position into an activated blocking position, in which the chamber passage is at least diminished with respect to its basic position, in order to block an air flow from the supply port to the delivery port and enabling exhaust air flow.
