Abstract

The electronically controlled electro-hydraulic step by step motor is for driving the elements of a machine which is operated in successive steps. It is composed of an electrical part (electronically controlled step by step motor) and a hydraulic part (hydraulic amplifier for the hydraulic motor couple end controlled valve). The electrical part (2) is composed of at least two step by step motors (4, 5) which cooperate with the servo-feeler (12) of the valve (13) via a common mechanism such as a differential gear mechanism. The resolving powers of the step by step motors (4, 5) are different.
