Abstract (en)

[origin: DE19735111A1] The piston (7) functions dependent upon the pressure difference between two positioning pressure conduits (13,14) connected with one of the positioning pressure chambers (11,12). The positioning pressure ruling in the conduits (13,14)is predetermined by two control conduits (33,34). A brake valve (19,20) is provided for each positioning pressure chamber (11,12), which throttles the back flow of pressure fluid from the positioning pressure chamber into a pressure fluid tank (21).
