Abstract
A pressure cap for openings in tanks, in particular in automobile radiators, has an outer cap component which is provided with a locking element that can be connected to the tank's neck, and provided with a handling element rotatably mounted in relation to said locking element, and furthermore provided with a coupling insert which is anti-rotationally mounted in the handling element and which can be axially engaged in and disengaged from the locking element to allow a releasably non-rotational connection between the locking element and the handling element. The pressure cap is furthermore provided with a valve assembly containing a valve body that can be axially moved back and forth, for releasing and blocking flow connections between the inside and the, outside of the tank depending on the pressure prevailing inside the tank. To create an anti-rotation means directly governed by and in time and sequence with the conditions prevailing inside the tank, it is provided that the engaging and disengaging movement of the coupling insert is derived from the pressure-dependent axial movement of the valve body of the valve assembly.
