Abstract: Closing bodies serve to control a pressure medium flow flowing via a fluidic valve. The closing body is mounted in an axially displaceable manner in a bore of the valve. It has a sealing section, interacting with a seating edge of the valve, and a guide section which serves to guide the valve cone in the bore. The guide section is provided with recesses which allow an overflow of pressure medium between the two sides of the closing body. The production of such closing bodies is expensive. In order to produce such closing bodies in a more cost-effective manner, the guide section of the closing body is of cylindrical form and its surface is provided with at least one helical groove which leads from the one side of the guide section to its other side. The closing bodies are used in particular in constant pressure valves for controlling fluid pressure medium. The sealing section of the closing body is normally of conical form.
