A rotary-piston machine (10) comprising a housing (5) having a cavity (9) and a rotor (2) received in the housing (5) is disclosed. The rotor (2) has a rotor axis (A) and a peripheral surface (21), inlet and outlet passages in communication with said cavity (9), one or more vanes (1) radially slideable received in slots in the rotor (2), each vane (1) extending radially from the internal surface (20) of the housing (5) to the rotor axis (A), and at least one working chamber (9a) being part of the cavity (9) and is defined by the internal surface (20) of the housing (5), the peripheral surface (21) of the rotor (2) and the side surface of at least one vane (1). Each vane (1) is rigid and journalled in a fixed axle shaft (8) having a central axis (B) being coincident with the axis extending centrally through the cavity (9) of the housing (5), which axis (B) extend in parallel with and spaced a distance (d) from the rotor axis (A). The rotor (2) proper constitute the unit for power take off or power input. The internal peripheral surface (20) of the housing is circular in any cross section. Each vane (1) is rigid (without joint) and tiltable arranged in a bearing (3) in the rotor. The bearing (3) is such arranged that each vane (1) is radially slideable in respect of the rotor (2) simultaneously as the vane (1) is able to tilt or oscillate within said bearing (3) in the rotor (2). Each radial section of the vane tip may have the form of a circle sector having centre of curvature coincident with the central axis (B) of the housing (5). |
