Improved pressure adapter for hydraulic system

Abstract

A pressure adapter having a first assembly and a second assembly, movable in rotation relative to each other along a main axis, the first assembly has a casing and a cam, the second assembly has a cylinder block with a plurality of housings in which pistons slide. Each piston is positioned in a housing. Each pair formed by a piston and a housing defines between the piston and the housing a first chamber and a second chamber distinct from each other. The first chamber and the second chamber define distinct displacements, in which the assembly of the first chambers performs a hydraulic motor function, adapted to be connected to a supply providing a first flow rate Q1 at a first pressure P1 and to perform a relative rotation of the first assembly and the second assembly, the assembly of the second chambers performs a hydraulic pump function, adapted to deliver a second flow rate Q2 at a second pressure P2.
