<p>The invention relates to a rotary machine for delivering liquids or gases, the invention is a rotary machine for delivering liquids or gases comprising a driving unit (2) coupled with a rotating part (11), a housing (1) provided with suction and delivery openings (5, 7) and a stationary part (3) arranged in said housing (1). The machine according to the invention may be a pump or compressor and is very advantageous among others for pumping corrosive and erodent fluids or compressing gases, wherein, according to the invention, the rotating part (11) is provided with rolls (15) rotatably mounted on shafts (16) arranged radially with respect to the axis of rotation (6) of the machine, said stationary part is an elastic disc (3) provided with channels (8) within said disc (3) and with ribs (25) on the surface facing the rolls (15) along said channels (8), wherein each of the channels are including an angle with the respective radii (R) and one end thereof is connected to the suction opening (7), the other one to the pressure opening (5). The rolls (15) are of conical shape having a greater diameter radially outside than inside and are arranged in uniform distances from each other along a circle coaxial with the axis of rotation (6). The respective heights (h) of the ribs (25) are greater than that of the channels (8) in the same axial directions. The elastic discs (3) preferably consist of two parts (3a, 3b) in axial direction: a support part (3a) at the front wall of the housing and a pressed part (3b) facing the inside of the housing (1), the channels (8) being between these two parts (3a, 3b).</p> |
