Abstract
A device is provided for the emergency operation of at least one closure element of a cooling air supply apparatus and a correspondingly implemented cooling air supply apparatus for an internal combustion engine of a motor vehicle, a closure element being mechanically operationally linked to an actuator. The closure element is situated so it is movable between a closed position, in which it essentially closes a ventilation opening, and an open position, in which it releases the ventilation opening for cooling air to flow through. The actuator automatically transfers the closure element into the open position if a predetermined temperature is exceeded.
Claims12
A device for emergency operation of a closure element of a cooling air supply apparatus for an internal combustion engine of a motor vehicle, comprising:
- an actuator that is mechanically operationally linked to the closure element;
- and
- a ventilation opening that is essentially closed by the closure element when the closure element is in a closed position and cooling air flows through the ventilation opening when the closure element is in an open position,
- wherein the actuator is configured to automatically place the closure element into the open position if a predetermined temperature is exceeded and is coupled to a restoring mechanism that transfers the closure element into the closed position if there is a temperature drop below a predetermined temperature level, the actuator being separate and distinct device from the restoring mechanism.
A cooling air supply apparatus for an internal combustion engine of a motor vehicle;
- comprising:
- a first operable closure element;
- and
- a second operable closure element, the second operable closure element comprising:
- an actuator that is mechanically operationally linked to the second operable closure element;
- and
- a second ventilation opening that is essentially closed by the second operable closure element when the second operable closure element is in a closed position and cooling air flows through the second ventilation opening when the second operable closure element is in an open position,
- wherein the actuator is configured to automatically transfer the second operable closure element into the open position when a predetermined temperature is exceeded and is coupled to a restoring mechanism that transfers the closure element into the closed position if there is a temperature drop below a predetermined temperature level, the actuator being separate and distinct device from the restoring mechanism.
