ABSTRACT:
The invention relates to a fluid engine constituted by cylinders divided into two groups, by a valve bank which comprises two enclosures connected selectively to a source of fluid and to a reservoir, and connecting each cylinder of a first group, with the said enclosures, successively, and by means for selecting the speed of the engine, which means comprise a movable member adapted to occupy two positions which, in a first position, creates a communication between the cylinder of the second group and the enclosures, successively, and in a second position, isolate said cylinders from one of the enclosures.
Said engine comprises a shuttle valve which, when the movable member is in its second position, connects the cylinders of the second group to that of the two enclosures which contains the fluid under the lowest pressure.
The invention finds an application in the production of a mechanically reliable reversible engine.
