Valve device for a system for a vehicle and system for a vehicle

A valve device for a system for a vehicle, the system having a first control unit and a second control unit, the first and second control units being electrically connectable or connected to the valve device, comprising:

• a valve unit for setting a pressure of a working medium for the system, wherein the valve unit has at least one actuator for actuating the valve unit;
• a first supply port for the electrical connection of the actuator to the first control unit, a second supply port for the electrical connection of the actuator to the second control unit, a first main port for the electrical connection of the actuator to the first control unit and a second main port for the electrical connection of the actuator to the second control unit;
• a first electric protective circuit and a second electric protective circuit, wherein the first protective circuit is electrically connected between the first supply port and the second supply port and the actuator, wherein the second protective circuit is electrically connected between the actuator, and the first main port and the second main port, and wherein each protective circuit has an electrical fuse device and a diode element that are integrated in series in at least the first and/or second supply port or at least the first and/or second main port;
• and
• a valve housing for accommodating the valve unit and the protective circuits;
• wherein the valve unit has at least one further actuator for actuating the valve unit, wherein the valve device has at least one third supply port for the electrical connection of the further actuator to the first control unit, at least one fourth supply port for the electrical connection of the further actuator to the second control unit and at least one further protective circuit, wherein the further protective circuit is electrically connected between the third supply port and the fourth supply port, and the further actuator, and wherein the second protective circuit is electrically connected between the further actuator, and the first main port and the second main port.

A system for a vehicle, comprising:

• a first control unit;
• a second control unit;
• and
• a valve device, including:
• a valve unit for setting a pressure of a working medium for the system, wherein the valve unit has at least one actuator for actuating the valve unit;
• a first supply port for the electrical connection of the actuator to the first control unit, a second supply port for the electrical connection of the actuator to the second control unit, a first main port for the electrical connection of the actuator to the first control unit and a second main port for the electrical connection of the actuator to the second control unit;
• a first electric protective circuit and a second electric protective circuit, wherein the first protective circuit is electrically connected between:
• (i) the first supply port and the second supply port, and (ii) the actuator, wherein the second protective circuit is electrically connected between:
• (i) the actuator, and (ii) the first main port and the second main port, wherein each of the first and the second protective circuits includes a respective electrical fuse device and a respective diode element that are integrated in series in at least the first and/or second supply port or at least the first and/or second main port;
• and
• a valve housing accommodating, inside the valve housing, the valve unit and the first and the second protective circuits including the respective electrical fuse devices and the respective diode elements;
• wherein the first and the second control units are electrically connectable or connected to the valve device.
