Description

The invention relates to a control device for the control of a hydraulic consumer having a hydraulically actuable directional valve in accordance with the description herein. The invention furthermore relates to a hydraulic pilot control device in accordance with the description herein.
Hydraulic control devices having hydraulically actuable directional valves are used inter alia in hydraulic systems of vehicles. A plurality of directional values are expediently interlinked in the form of valve disks in a so-called control block. Using such a hydraulic control device, lifting devices of a lift truck or of an agricultural tractor, loading cranes, the bucket of a wheeled loader or also driving and steering functions of a vehicle are operated hydraulically; in the event of a control regulated by flow requirement (load sensing), individual valve disks have a pressure balance for the control of the hydraulic pressurizing medium flow flowing across the valve.
Mineral oil is usually used as the hydraulic pressure fluid or pressurized medium in industrial hydraulics and mobile hydraulics. However, a water-based pressurized medium is also used for certain areas of appliion. The term fluid will be used in the following for hydraulic fluids.
