  • Patent number: 11617982
    Abstract: An arrangement for a utility vehicle includes at least one air dryer unit and a regulating unit, wherein the air dryer unit and the regulating unit are designed in each case as separate units. The air dryer unit has at least one air dryer module, in particular an air dryer cartridge, at least one discharge valve and at least one control line for the pneumatic control of the discharge valve. At least one connecting line is provided in the air dryer unit with connection to the air dryer module. The connecting line leads directly to a consumer non-return valve for the air dryer unit, which is arranged outside of the air dryer unit, wherein the connecting line can be used at least partially bi-directionally and/or can be or is connected to a bi-directionally usable line section.

  • Publication number: 20210316704
    Abstract: A pneumatic braking device for a utility vehicle includes at least one pneumatically controllable spring accumulator for a parking brake of the utility vehicle and an electronic parking brake device. The electronic parking brake device has at least one electronic control unit, at least one bistable valve unit, at least one first valve unit by which a parking brake of a trailer of the utility vehicle can be deactivated when activating the parking brake of the utility vehicle, at least one second valve device which can be connected in such a way that when there is a decrease in the system pressure for supplying the parking brake of the trailer, the parking brake of the trailer can be activated, and a traction vehicle protection valve.

  • Patent number: 10337534
    Abstract: A vehicle pressure medium device in which a pressure medium flows, has a multilayer design which has at least two mutually contacting layers. A groove-shaped recess is arranged between a first chamber into which a first flow opening opens and a second chamber into which a second flow opening opens when viewed on a plane parallel to the layers. The groove-shaped recess has at least one opening for a fluidic connection between the first chamber and the second chamber on a plane parallel to the layers. A group of molded seals is provided for mounting between the two layers. A fluidic connection is either produced between the first chamber and the second chamber or not depending on the molded seals which are mounted between the two layers and each of which is selected from the group of molded seals.
