Abstract

This invention relates to a multiway valve for controlling the flow of a pressure medium from a fluid supply conduit or an exhaust conduit to a fluid delivery conduit comprising
  • a valve housing (1) with a substantially cylindrical axial hole which has a plurality of annular steps (9) forming inner chambers with corresponding outer ports (2, 3a, 3b, 4a, 4b) for connecting said conduits,
  • means for switching the fluid flow between said ports (2, 3a, 3b, 4a, 4b) guided axially movable in said hole and
  • means for moving said switching means relative to said valve housing (1) disposed on at least one end of said switching means.
    • According to the invention said steps (9) form at least two inner chambers for the delivery port (3a, 3b) and also at least two inner chambers for the exhaust port (4a, 4b).
