Abstract
A device for delivering flowable materials from a production bore (2), consisting of a source of pressurized medium (1), a pressurized medium conduit (3) for conducting the pressurized medium into the bottom area of the bore, the pressurized medium being used to operate drive means (5) coupled to a pump (6) for the flowable material. The drive means (5) and the pump (6) are both rotary displacement devices having a spiral rotor (10, 12) which describes an eccentric rotational path within a spiral stator (11,13). The rotor (10) and the stator (11) of the drive means (5) and the rotor (12) and the stator (13) of the pump (6) have the same eccentricity and are rigidly connected to one another.
