ABSTRACT:
This invention relates to a fluid mechanism with two cylinder capacities, comprising a distributor valve defining first and second enclosures containing supply and exhaust fluids comprising two groups of distribution conduits, and a device for selecting the cylinder capacity, constituted by a bore and a slide element for selection. According to the invention, a first and a second connection conduit connect the first and second enclosures to the bore and open out between transverse planes; distribution conduits open out in the bore between these planes; and the slide element comprises a groove contained between said planes and establishing communication between the distribution conduits and the connection conduit. One application of the invention is the production of a compact motor.
