Hydraulic energy storage for electrohydraulic actuator utilized for clutch i.e. double clutch, has plate spring device designed, mounted and prestressed in such manner that spring force value changes around relatively small force amount
The storage (1) has a plate spring device (20) exerting a plate spring force for storage of energy, where the plate spring force depends on a plate spring path. The plate spring device is designed, mounted and prestressed in such a manner that the value of plate spring force changes around relatively small force amount during load cycle of the storage in a nominal force area, where the plate spring path changes around relatively a large path amount in a nominal path area. The plate spring device cooperates with a piston (10) that moves back and forth. An independent claim is also included for an electrohydraulic actuator comprising a diaphragm spring.
