PCT No. PCT/EP91/01041 Sec. 371 Date Apr. 23, 1992 Sec. 102(e) Date Apr. 23, 1992 PCT Filed Jun. 6, 1991 PCT Pub. No. WO92/03325 PCT Pub. Date Mar. 5, 1992.A device for actuating the control valve (14) of a hydraulic power steering system for automotive vehicles, the rotary motion of a steering wheel being transmitted by means of a steering shaft (2) and the steering torque being transmitted by a relative rotation between the steering shaft (2) and a pinion shaft (4), and wherein the control valve (14) is a linear slide valve. A sleeve (6) embracing the steering shaft (2)and the pinion shaft (4) converts the relative rotation between the two shafts into an axial displacement axially and helically extending coulisse-type guides (7, 8), angularly disposed to one another, within which pins (9, 10), rigidly coupled to the steering shaft (2) and the pinion shaft (4), are received.
