The drive mechanism includes housing (19) with an inlet port (19a) and an outlet port (19b) for the liquid. The conduit has a first end linked to the outlet (10) and a second end linked to the outlet port (19b) of the housing (19) of the drive mechanism. The drive wheel (26), in the form of a Pelton wheel, is part of the housing (19) of the drive mechanism. The drive wheel (26) includes a plurality of paddles and is mounted such that the paddles face the inlet port (19a).
