Abstract (en)

[origin: EP1344945A2] The valve combination consists of pressure scales, a load holding valve and a proportional valve, the piston of which can move axially in borings in one or more housings containing input and output cavities. The proportional valve (2) has a hollow piston, and the load holding valve (3) and pressure scales (1) have stacks of laminar disks (6) to relieve the main part of excess energy.
