Abstract (en)

[origin: WO2014108616A1] A hydraulic machine comprising a barrel (12) driven in rotation by an input shaft (6), comprising cylinders (14) each receiving a piston (16) bearing on one side on a tiltable tray (20) that can pivot about an axis perpendicular to the input shaft, the cylinders bearing, on the side opposite the tray, on a circular closing plate (24) comprising a low pressure manifold and a high pressure manifold separated at the ends of same by two intermediate spaces, at least one of these spaces comprising at least one connection to a precompression chamber, characterised in that the tilt of the tray (20) comprises a second tilt angle that gives an angular offset of the top and bottom dead centres of the pistons (16), relative to the mid points of the intermediate spaces.
