Abstract:
Oscillating motor comprisinga stator (1) with a casing (3) and covers (4) disposed on two sides, wherein at least one stator wing (6) is disposed in the casing (3), and a rotor (2) with a driven shaft (7) supported in one of the covers (4) and with a number of rotor wings (10) corresponding to the number of stator wings (6), wherein the stator wing (6) and the rotor wing (10) in connection with the casing (3), with a cylinder part (9) of the driven shaft (7) and with the two covers (4) form at least one pressure chamber (13) and one discharge chamber (14), and wherein the pressure chamber (13) and the discharge chamber (14) are sealed inwardly by a frame sealing element (20) inserted into the stator wing and inserted into the rotor wing (10,6), and the pressure chamber (13) and the discharge chamber (14) are sealed outwardly and inwardly by an anullar sealing element, wherein the anullar sealing element comprises the sliding sealing ring (23) and a soft sealing ring disposed on the side of the pressure chamber (13) and of the discharge chamber (14) and wherein the sliding sealing ring (23) and the soft sealing ring are disposed on a common axis, characterized in that the sliding sealing ring (23) is disposed axially shiftable on a bearing pin (8) of the driven shaft (7) and rests at the inner face of the cover (4) with a sliding and sealing face and wherein anullar channels (33, 35) are disposed on the cover side of the sliding sealing ring (23), wherein the anullar channels (33, 35) are connected to the side of the sliding sealing ring (23) disposed toward the pressure chamber (13) or, respectively, the discharge chamber (14) through pressure balancing bore holes (34) and pressure balancing channels (38).
