Abstract (en)
- A hydraulic system (101) for an industrial truck is presented. The hydraulic system (101) comprises: a reservoir (107) having an inlet (107b) and an outlet (1 07a); a hydraulic apparatus (102) having a first port (1 05a), connected to the outlet (107a), and a second port (105b) connected to a consumer (112). The inlet (107b) is connected to the first port (105a) via a first valve (110) and to the consumer (112) via a second valve (114). Each of the first and second valves (110, 114) is switchable between a first state allowing fluid flow towards the reservoir (107) and a second state blocking fluid flow towards the reservoir (107). A fluid flow from the consumer (112) to the reservoir (107) is controllable so as to pass through at least one of the first and second valves (110, 114). - A method of energy regeneration in a hydraulic system is also presented.
