Disclosed is an electrically-driven liquid filter pump comprising a liquid filter (6A, 6B) and an electrically-driven liquid positive displacement pump for delivering a liquid medium in a delivery circuit or at least in a delivery section. The liquid filter pump has: a pump housing (1, 11) comprising a hollow-cylindrical pump chamber (10) and at least one inlet (12) and at least one outlet (13); a cylindrical journal (2) with a guide slot (23), in which a locking vane (3) is held; a rotor (4) with an innerlying cam profile (41), the rotor being rotatably mounted on the journal (2); and a stator (5) surrounding the rotor (4) and having stator coils (50). One end of the locking vane (3) separates the volume of a cam chamber (40) into a decreasing section and an increasing section, thereby allowing the liquid medium to be delivered through at least one inlet (12) and at least one outlet (13) on either side of the locking vane (3). A channel (7) extends through the pump housing (1, 11) and the journal (2), the channel connecting, on one side of the pump housing (1, 11), one end of a filter circuit running through the liquid filter (6A, 6B) to, on the opposite side of the pump housing (1, 11), one end of the delivery circuit or the delivery section. |
