Abstract

Hydraulic device for driving, in synchronism and with an alternating movement, two or more than two members, in particular motor vehicle windshield wipers, comprising at least two reciprocating motors, the pistons of which are provided with interceptor members, the pistons of which are provided with spring intercepting members, to control the communication between the pressure chambers of said motors and the outlet, said pressure chambers being fed by means of only one pressure source with a continuous flow through a distributor, characterized by means (T1-T4 and 138-140) connected operatively with the mobile equipment (58-26) of the distributor (I) and by means of fluid under pressure (S, K) that respond to the pressure that is formed, each time, in at least part of the engine chambers (M-Mp), to control the operation of the driving means (T1-T4-138-140) mentioned above, so as to locate and retain r Stably move the distributor equipment (T) in two preselected positions, while continuous switchable connections to said positions are provided for at least part of the chambers (Ml, Mp2) of the drive motors, to connect said motors with the inlet duct (Ma) and the outlet duct (Sc) of the pressure generator.
