Abstract (en)
[origin: WO2019149753A1] The invention relates to a vane motor (1), comprising a rotor body (2), which is driven by compressed air and which has vane gaps (3) for radially movable vanes, and a rotor shaft (4) for rotatably mounting the rotor body (2) with respect to a motor bush (11). In order to provide a vane motor (1) and a method for lubricating a vane motor (1) that ensure particularly long, low-maintenance operation, the vane motor (1) being easy to maintain and being capable of particularly economical and environmentally friendly operation, it is provided that the rotor shaft (4) is designed as a hollow shaft having a first lubricant reservoir (5) in the interior, the first lubricant reservoir (5) having a lubricant introduction opening (6) accessible from the exterior (Ä) of the vane motor (1), and the first lubricant reservoir (5) being connected, by means of at least one radial lubricant bore (7), to at least one further lubricant reservoir (50) arranged in a portion (20) of the rotor body (2) between two vane gaps (3) and/or to an outlet opening (8) arranged in one of the vane gaps (3) for feeding lubricant into the vane gap (3).
