Hydraulic vane cell machine

摘要

At least one vane cell(5) on its end lying against the guide contour(4) has a wear strip(22). A channel arrangement(18) is provided between the HP and LP sides(13,14) which is blocked so long as the wear strip has a predetermined thickness, and is open if the strip is thinner than the prescribed amount. The channel arrangement has at least one movable channel(17) located in the cell and at least one stationary channel(11) located in the rotor.
