Abstract
Eine Vorrichtung zum Dämpfen von Schwingungen in Flüssigkeiten weist ein mit einer Druckmittelzuführöffnung und Druckmittelabführöffnungen versehenes Gehäuse auf, in dem ein geführter Kolben einen Druckmittelzuführraum von einem Druckmittelraum trennt. Durch im Kolbenboden angeordnete Drosselbohrungen korrespondiert der Druckmittelzuführraum mit dem Druckmittelraum. Eine an einer druckmittelraumseitig am Kolben angeordnete Kolbenstange führt eine den Kolben in seiner Bewegung beeinflussende Feder. Zur Erzielung einer material- und bauvolumen-optimierten Vorrichtung, die wenige fertigungstechnisch nicht aufwendig erstellbare Bauteile umfaßt, wird der Druckmittelraum zum Teil durch einen zwischen den Kolbenschaft des als Hohlkolben ausgebildeten Kolbens und der Kolbenstange befindlichen Ringraum gebildet.A device for damping vibrations in liquids has a housing provided with a pressure medium supply opening and pressure medium discharge openings in which a guided piston separates a pressure medium supply space from a pressure medium space. The pressure medium supply space corresponds to the pressure medium space through throttle bores arranged in the piston crown. A piston rod arranged on the piston on the pressure medium chamber side guides a spring which influences the movement of the piston. In order to achieve a device that is optimized in terms of material and volume and comprises a few components that are not costly to manufacture from a manufacturing point of view, the pressure medium space is partly formed by an annular space located between the piston shaft of the piston, which is designed as a hollow piston, and the piston rod.
