The fluid conduit (8) has a cut-off valve (10) and a sensor located upstream from the cut-off valve. The fluid conduit is provided with a degassing conduit extending upwards from the fluid conduit and provided in its upper part with a valve device (50). The valve device incorporates a float (53) which can float upwards on the fluid in the degassing conduit in order to seal directly against a seat (51). A drive component (56) from the upper side of the seat drives a sealing body (57) to and from sealing contact with a throughflow channel (52) through the seat. The sealing body on insertion in the seat channel drives the float away from contact with the seat. The drive component holds the sealing body in sealing engagement with the channel when the sensor establishes the absence of gas bubbles in the fluid in the conduit (8). |
