Abstract
A valve ( ) for a motor vehicle air spring ( ) having an ancillary volume ( ) provides a finely metered continuous opening up to the complete cross section without throttle and a stable performance for flow forces results. The valve ( ) is characterized by a star nozzle ( ) which includes any desired number of slots n ( ) which mutually intersect and each slot has the length D ( ) and a width s ( ) and the slots are arranged so as to be concentric. The star nozzle peripheral length L ( ) is increased compared to a round nozzle L . For the valve cross section, A =L ·H applies. The throughput cross section A of the star nozzle ( ) is so large that it corresponds at least to the cross section A of the inlet ( ) and the outlet ( ). A preferably triangular-shaped valley-like recess ( ) is provided between each two mutually adjacent ones of the slots ( ). The sealing body ( ) of the valve ( ) is preferably configured as a collar. The valve ( ) can be provided with a second collar ( ). The star nozzle valve ( ) is applicable in all areas where a large cross section must be completely cleared at low switching times and forces.
