Definitions

  • the invention relates to a rotary piston blower in which a component rotating about an axis of rotation is equipped with a plurality of conveying blades which can be pivoted on axes and which are steered by a cylindrical guide part which is arranged eccentrically to the axis of rotation in such a way that the space which results between the blade surfaces on the one hand and the housing wall on the other occupies the largest and smallest possible volume with each full revolution.
  • blowers which work according to the displacement method and whose operation is not possible without frictional losses even with great manufacturing accuracy, is to convey gases, such as mainly air, against pressure levels caused by centrifugal force. (Radial) or propeller (axial) fans with economically applicable speeds can no longer be reached.
  • a rotary lobe blower of this type known from FR-PS 975 985
  • pivoting rotary conveyor blades in a control housing located outside the medium to be conveyed are controlled by levers which scan a stationary cylindrical guide part which is attached to the center of the axis of rotation.
  • this blower has constant friction — the rotating guide lever on the fixed guide part.
  • the rotating conveyor blades on three of four circumferential sides are designed to be as frictionless and tightly sealed as possible with respect to the fixed housing. This is only possible to a limited extent by means of one-sided guidance of the blades and requires a high mechanical outlay.
  • the invention has for its object to eliminate the deficiencies of the blower according to FR-PS 975 985 by simplifying the sealing of the conveyor blades against the housing and reducing the friction losses.
  • the rounded, lighter end of the conveying blades 3 which are mounted outside their center of gravity, lie against the cylindrical guide part 2.
  • the latter accordingly results in a rotating boundary surface of the conveying cavities formed by the conveying vanes 3 without any significant friction of the conveying vanes 3 on the guide part 2 occurring.
  • the weight and area distribution of the conveyor blades 3 in relation to their respective axis 4 should be chosen so that the conveyor blades 3 are only slightly due to the centrifugal force, but due to the back pressure of the conveying medium to a greater extent to the cylindrical guide part 2 be pressed.
