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.
Characteristic
1. Compact structure, light
2.Strong durability
3.Various panel options
4.Handle form can meet the requirements of ergonomics
5.Typically used in cranes, construction equipment, agricultural
equipment, mining equipment. Installed on operating mechanism or
pilot operated valves.
