Abstract

A valve unit for an electro-pneumatic brake control device for controlling a parking brake of a vehicle includes at least one air-quantity-boosting valve device for aerating and venting at least one spring brake cylinder of the parking brake and at least one electrically actuatable control valve for controlling the air-quantity-boosting valve device. To simplify the construction of the brake control device, the air-quantity-boosting valve device and the control valve are integrated in a common integral valve block.
