Abstract
A valve arrangement () of a tractor vehicle () for controlling a pneumatic brake system of a trailer vehicle () includes a trailer control valve () with a reservoir pressure input (p) for the introduction of reservoir compressed air and a reservoir pressure output (p) for the controlled discharge of reservoir compressed air. The reservoir pressure output is pneumatically connected to a 'reservoir' coupling head () of the tractor vehicle. A shut-off and ventilation valve () is arranged in a reservoir pressure line () upstream of the “reservoir” coupling head. Before connecting an associated coupling head of the trailer vehicle () to the “reservoir” coupling head of the tractor vehicle, the feed of reservoir compressed air to the “reservoir” coupling head can be shut off to ventilate the “reservoir” coupling head. After reconnecting the associated coupling head, the “reservoir” coupling head can be charged again.
