<p>The invention relates to a rotary piston device, of pump or compressor-type, which may be used for pumping, compressing and sucking up fluids. According to the invention, the rotary piston device ensures the pumping, compressing and sucking up of fluids by the fact that the rotor (2) comprises a ball provided in its medial area with the circular slot (9) playing the role of a pumping chamber, and, in the central area there is provided with a disc-shaped shutter rotary piston (6), which may rotate inside the rotor (2) actuated by some bevel-gear wheels (11 and 12), actuated in their turn by an axle (13), which performs at the same time a rotary motion around itself and a rotary motion together. with the rotor (2), motion synchronized with the motion of the rotor (2). A negative-pressure region is formed behind the rotary shutter piston between the housing (1) provided with a statical shutter (3) and the rotary shutter piston (6), having as effect the sucking up and the discharging of working fluids.</p> |
