Abstract
A control valve () for applying a spring-loaded brake pressure (p) to spring-loaded parts of a rear-axle wheel brake is provided. The control valve () is activatable pneumatically via a second control input () with a parking-brake control pressure (p). The parking-brake control pressure (p) can act in such a manner on a control mechanism () arranged in a valve housing () of the control valve () that a spring-loaded brake pressure (p) arises at a control output () of the control valve () as a function of the parking-brake control pressure (p) for bringing about a parking-brake braking specification with the spring-loaded parts of the rear-axle wheel brakes. The control valve () has a first control connection () connectable to an adjustable first control chamber (), which is operatively connected to the control mechanism ().
