Patent number: 10570804Abstract: A regulator has a regulation unit (422, 622) with an adjustment unit (624), having a drive unit (414, 620) configured for adjusting the adjustment unit (624), and having a lockable and unlockable force store (412, 610-616). The regulation unit (422, 622) and the adjustment unit (624) are in contact with one another via the force store (412, 610-616), and the regulation unit (422, 622) can, in the case of a locked and charged force store (412, 610-616), be displaced by the adjustment unit (624) within an adjustment range (630) so as to drive the force store (412, 610-616). In the event of unlocking the charged force store (412, 610), a discharge of the force store (412, 610-616) causes the regulation unit (422, 622) to be moved automatically into a safety position independently of the adjustment unit (624).Type: GrantFiled: August 2, 2017Date of Patent: February 25, 2020Assignee: Dr. Ing. h.c.F.
