Abstract
A valve arrangement for vibration decoupling has a housing, in which two valve bodies are accommodated, a first of which is biased by a spring in a reference direction towards a stop integral with the housing and has a through-path for fluid. The other housing is biased by a spring in an opposite direction towards a valve seat on the first valve body and lifts away from the latter in the event of a volume flow in the reference direction, so as to open the through-path for fluid. A further through-path for fluid is provided between the first valve body and the housing, wherein a further valve seat is formed on the stop integral with the housing, towards which further valve seat the first valve body is biased by a spring and lifts away from the valve seat in the event of a volume flow in the opposite direction.
