Abstract

A hydraulic transmission circuit comprising three or four coupled hydraulic elementary motors, each elementary motor having a first and a second secondary enclosure. The circuit includes four distribution valves for which the respective outlet channels may be selectively connected to two main conduits for supplying fluid to and discharging fluid from the circuit. The outlet channels of the first and second valves are connected to at least one of the first secondary enclosures; those of the third and fourth valves are connected to at least one of the second secondary enclosures. Each of the elementary motors has a first secondary enclosure connected to a single valve from among the first or second valve and a second secondary enclosure connected to a single valve from among the third or fourth valve. The valve pairs thereby connected to said elementary motors respectively, are all distinct, two by two.
