ABSTRACT:
A valve which is formed by a face of a valve body and the outlet area of an opening in a counterpart is disclosed. An extension dipping into the opening to ensure smooth evolution of the beginning of opening operation is known. The opening behavior achieved in this manner is not sufficient for all applications. In order to further smooth the evolution of the beginning of the opening operation, a clearance fit is provided between the extension and the opening which is interrupted by a countersink in the extension or in the opening. The countersink is formed and placed in such a manner that it comprises the counterpart of the clearance fit and at least one inclined control edge and, thereby, an adjustable choke which can be controlled in series with the valve. The countersink can take the form of a groove. Valve arrangements for compressed-air systems in motor vehicles represent a special area of application for the invention.
