Abstract

1. Filling device for introducing fresh water into a closed heating installation, comprising (a) a pressure reductor (1) connected on the inlet side to a fresh water conduction, (b) a tube separator (20) connected to the outlet side of the pressure reductor (1) and having a water-carrying movable member (23), - which in a first operative position is advanced and establishes a connection between a fresh water outlet (22) communicating with the outlet of the pressure reductor (1) and the heating installation, bridging a point of separation (15), - which, in a resting position, ends upstream from the point of separation and closes the fresh water outlet (22), and - which is displaceable by a servomotor to which is applied the fresh water pressure from the resting position to the operative position, (c) a backflow preventor (7) arranged downstream from the tube separator (20) and the point of separation (15) and connected to an inlet of the heating system, and (d) a control arrangement (40) arranged to control the application of the fresh water pressure to the servomotor, characterized in that (e) the control arrangement (40) comprises a differential pressure sensor (41) on which is applied, on one side, the pressure from the outlet of the pressure reductor (1) and, on the other side, the pressure in the heating system, (f) the servomotor for the tube separator (20) is arranged to be controlled by the differential pressure sensor (41) such that - the tube separator (20) is moved, with a first pressure in the heating installation which is equal to the pressure at the outlet of the pressure reductor, to its resting position, and - the tube separator (20) is arranged to be advanced to its operative position with a second pressure in the heating installation which is less than the first pressure.
