<p>The system has functional units with a vacuum collector, a flow meter (37) and a cartouche type solenoid control valve, where the units are regrouped in a removable block fixable on a cover (3) and housed in housing, that is provided in a coupling face (8) of the block. The cover integrates passages (16) which are required for operations of the units and which emerge on a coupling face (9) of the cover, where the faces are mutually conformed. The passages and the housing are respectively connected when the block is mounted on the cover and when the faces are mutually cooperated.</p> |
