ABSTRACT:
An apparatus for tapping a fluid through a wall, comprising a vacuum source (24), a tapping head (1) provided at the front thereof with a circumferential seal (3) bounding a contact area, perforating means (4) to be brought into a position extending through the contact area, and at least one conduit (11, 111, and 211) communicating with the contact area for discharging air from the contact area enclosed by the seal (3) and for discharging fluid released. The invention provides an apparatus for easily and reliably tapping fluid that may be under excess pressure through a wall. In the contact area a reduced pressure can be generated by the vacuum source, resulting in that the tapping head is held against the wall and moreover no fluid can release into the atmosphere.
