Abstract
A closing body is mounted in an axially displaceable manner in a bore of a fluidic valve to control a pressure medium flowing via the valve. The closing body has a sealing section, interacting with a seating edge of 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. To reduce costs of production, 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 one side of the guide section to its other side. The closing body is useful in particular in constant pressure valves for controlling fluid pressure medium. The sealing section of the closing body is normally of conical form.
