Abstract
The invention relates to a hydraulic circuit for supplying at least one motor incorporating "disengageable" pistons, comprising a fluid distributor valve obturating, in one of its positions, the supply and exhaust conduits of said motor. According to the invention, the fluid distributor valve comprises a shuttle valve presenting two inlet connections and one outlet connection, and, in said position, establishes communications of the supply conduit with one of the inlet connections, of the exhaust conduit with the other inlet connection, and of a conduit evacuating fluid towards a reservoir with said outlet connection of the shuttle valve. One application of the invention is the production of a vehicle translation circuit comprising a "disengageable" assistant motor.
