Abstract

The devices comprises a distributor () that presents distribution ducts opening out into a radial distribution face (A), and a distributor-counterpart engaged in each other in such a manner that two main enclosures () are provided between their opposite axially-extending faces. The device comprises a cylinder-capacity selector comprising two slides () arranged after the other in a bore () of the element engaged in the other, to which are connected the main enclosures () and at least some of the distribution ducts (). The slides are able to adopt at least three distinct configurations establishing different connections between the main ducts () and the distribution ducts via the main enclosures, in order to be able to obtain at least three distinct operating cylinder capacities.
