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.
Claims14
A valve unit for an electro-pneumatic brake control device for controlling a vehicle parking brake, the valve unit comprising a common uniform valve block, at least one air-flow-boosting valve device operable to admit air into and to vent at least one spring-actuated brake cylinder of the parking brake, and at least one electrically actuatable control valve operable to control the air-flow-boosting valve device, said common uniform valve block comprising a housing with a first recess and a second recess, said air-flow-boosting valve device being disposed in said first recess and said at least one control valve being disposed in said second recess, at least one of said first recess and said second recess comprising at least one guide for guiding at least one moveable part of at least one of said at least one air-flow-boosting valve and said at least one electrically actuatable control valve.
