Abstract
Mechanically controlled power transmission device comprising a rotary engine driving, through a lever and a clevis, a hydraulic slide valve which consists, in a known manner, of a rod sliding in a hole and includes blocks capable of selectively establishing communication between firstly a user device and secondly a high pressure source or an outlet. Two springs act on the slide valve in opposite directions, return the latter, in the event of a breakdown, into a neutral position which is preferably a position in which no communication is established. The device of the invention is for use in the motor car industry.
