LINEAR CONCENTRIC VARIABLE DISPLACEMENT PUMP/MOTOR SYSTEM

摘要

The present invention relates to a linear concentric variable displacement pump/motor system (1000) comprising a main rotor (10) comprising a cylindrical hole (60) extending along its center for receiving a piston guide and a cylindrical body (20), the cylindrical body (20) having two longitudinal grooves (30, 30') opposite to each other which receive the vanes (90) of the rotor; a secondary rotor (100); a main rotor synchronizer (200); a secondary rotor synchronizer (400); a piston (500) having a cylindrical shape and surrounding said main rotor (10), said blades (90) and said main rotor synchronizer (200), said piston (500) having a central hole (510) configured to receive a cylindrical guiding rod; and a housing (600) comprising two cylindrical inner chambers (610, 620) and having at least two channels (630, 630'), the front portion of the housing (600) having at least two additional holes (640, 650).
