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).
A regulator having a regulation unit (422, 622), having an adjustment unit (624), having a drive unit (414, 620) which is configured for adjusting the adjustment unit (624), and having a lockable and unlockable force store (412, 610-616), wherein 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 means of the adjustment unit (624) within an adjustment range (630) so as to concomitantly drive the force store (412, 610-616), wherein, in the event of unlocking of the charged force store (412, 610-616), a discharge of the force store (412, 610-616) which at least partially occurs here causes the regulation unit (422, 622) to be automatically moved into a safety position independently of the adjustment unit (624).
A method for operating an electronically controlled regulator having a regulation unit that is adjustable by an electronically driven adjustment unit, in which method a fail-safe function is realized by means of a lockable and unlockable force store which, in normal operation, in a charged and locked state, produces operative contact between adjustment unit and regulation unit and is driven concomitantly with the regulation unit during adjustment of the regulation unit and which, in a fault situation, is unlocked and thereby at least partially discharged, whereby the regulation unit is automatically moved into a safety position independently of the adjustment unit.
