Abstract
A suspension control valve arrangement for a pneumatic suspension system of a commercial vehicle includes a supply port, a delivery port, an exhaust port, a service valve arrangement, and an operation control mechanism (5, 6) for switching the service valve arrangement into one of the following normal operation modes of a normal operation status: a blocking position for a blocking mode for blocking an air supply from the supply port to the delivery port, a supply position for a supply mode for supplying air from the supply port to the delivery port, or an exhaust position for a normal exhaust mode for connecting the delivery port to the exhaust port. A dump-control device (7, 11) in the housing (2) is configured for switching between the normal operation status and a quick-dump mode (IV), win which the delivery port is connected to the exhaust port by bypassing the service valve arrangement.
