Abstract
A closure cap for a fixed neck of a container, especially of a motor vehicle radiator. The closure cap comprises a cap inner part provided with a flow connection between the inside of the container and the outside of the container. The cap inner part includes a valve assembly for releasing and blocking the flow connection. The valve assembly includes a valve body is able to move in a to-and-fro manner. It is pressed with a bias in a direction toward the interior of the container against a sealing seat. The valve body is biased so that it can lift from the sealing seat when a limiting value of the inner pressure of the container is surpassed. The bias can be adjusted by a drive controlled by the operation of the vehicle.
Claims26
A closure cap for a stationary connector of a container, the container defining an interior, the closure cap comprising:
- an interior cap element having a seal seat and a flow connection between the container interior and the container exterior;
- a valve arrangement for opening and blocking said flow connection, said valve arrangement having a valve body, which can be moved back and forth, and is biased in the direction toward the container interior against said seal seat so that it can lift off said seal seat when a threshold value of the interior pressure in the container is exceeded;
- and
- a controlled drive mechanism, wherein:
- said bias can be set by means of said controlled drive mechanism;
- and
- said drive mechanism is vacuum-controlled.
