Embodiment Construction
[0016] In Figures 1 to 3 a compact hydraulic unit 10 is shown with an electric motor pump unit 12 having a common housing. A valve housing 14 is secured to the casing of the motor pump unit 12, by means of which the motor pump unit 12 is mounted on the upper side of a hydraulic tank 16. A solenoid valve 18 is attached to the valve box 14 . For example, the hydraulic unit described is used to actuate a lift cylinder (not shown) in an industrial truck. When the motor of the motor pump device 12 is turned on, the liquid medium is delivered to the lifting cylinder from the storage tank 16. The valve element provides a check valve which prevents backflow of liquid media and maintains the lift cylinder at the set position. Activating the solenoid valve 18, the liquid medium will flow back from the lift cylinder, ie through a hose 20, which is shown in dashed lines in FIGS. 2 and 3 . Hoses are located within the tank 16 and lead to a filter unit 22 which will be described in more ...
