20080258412 | Roll Regulation Actuator - A roll regulation actuator for installation between two axially aligned rods, in particular between two rods of a stabilizer, includes a cylindrical housing and a device arranged in the housing for providing a torque acting on at least one of the rods. The device includes a first piston displaceable in the housing with a first piston rod having a first thread. The device further includes a first ball nut rotatably mounted in the housing. The first ball nut engages the first piston rod via a first counter-thread matching the first thread, and is able to be coupled to one end of a first rod. The device further includes a first pressure chamber acting on a first side of the first piston. | 10-23-2008 |
