The core (27) of the screw and/or its thread (28) is eccentric in relation to the rotation axis (30) of the screw and in relation to the mean screw line of the core respectively, in at least some of the thread turns in one zone (V) of said first pressure cone, and the jacket of this pressure cone (13) is impermeable in said zone (V).
