  • Vane with offset walls and fluid passages used in a vane cell device
    Patent number: 9650894
    Abstract: A vane for a vane cell device comprising a stator and a rotor rotatably arranged in the stator with a plurality of guide grooves in each of which a vane can be movably mounted along a direction of movement. The vane has a high-pressure side, and a low-pressure side facing the high-pressure side, for fluid conveyed or flowing through a workspace of the vane cell device. The vane has a first side wall formed on the high-pressure side and a second side wall formed on the low-pressure side, wherein the first and second side wall are connected to each other by a plurality of ribs forming lateral limits of fluid channels. The first and second side wall are offset relative to each other so that the high-pressure side is only partially covered by the first side wall, and the low-pressure side is only partially covered by the second side wall.
