ABSTRACT:
A valve arrangement is so constructed that a pressure limitation is attainable with minimal parts expenditure and without additional structural volume in a cost advantageous manner. On a shift piston of a pathway valve, a valve member of a pressure valve is arranged therewith. The pressure valve is installed within the structural volume of the pathway valve. Via a slight modification of the shift piston of the pathway valve and installation of the valve member as a single additional structural part there is eliminated additional pressure valve structure and system connection thereof necessary with known valve arrangement. With that the inventive valve arrangement fulfills preconditions made as to a mass product including particularly nominal structural volume, nominal number of structural parts, nominal disturbance susceptibility and extremely cost-advantageous production manufacturing.
