Abstract
Included in a connection arrangement is a valve device (4) which is so arranged as to be capable of longitudinal displacement inside a supporting device (3). During its opening movement the valve device is capable of displacement into a space arranged inside the supporting device, which space is sealed in relation to a fluid capable of connection to the arrangement with the help of the valve device and a sealing device (5a, 5b). An enclosed volume is thus formed with the help of the supporting, valve and sealing devices. Compressible air or gas enclosed within this volume assumes a first pressure with the valve device in its closed position, which first pressure preferably corresponds to atmospheric pressure, and assumes a second pressure which exceeds the first pressure with the valve device in its fully open position, which second pressure is less than the maximum pressure of the fluid. Alternatively, the volume which is sealed in relation to the aforementioned fluid may be in communication with the outside.
