Vorrichtung zur Kompensation von viskosen Eigenschaften eines hydraulischen Mediums in einer hydraulischen Druckleitung

摘要

An apparatus for compensating the viscous characteristics of a hydraulic medium in a pressure line ( 10 ) in which apparatus a pressure nozzle ( 12 ) with constant geometry and constant through-flow cross-section is located in the pressure line ( 10 ). It is provided according to the invention that in the pressure Line ( 10 ) upstream or downstream of the pressure nozzle ( 12 ) at least one channel-shaped area ( 11, 28 ) is made or situated which, compared to the pressure nozzle ( 12 ), has a smaller through-flow cross-section and a larger axial extension and that the control pressure (P_SekV) abutting between the channel-shaped area ( 11, 28 ) and the pressure nozzle ( 12 ) can be supplied via a control pressure line ( 13 ) to a shift valve ( 14 ).
