Definitions

  • the invention relates to a rotary piston machine, in particular a blower with a housing having an inlet and an outlet opening for a working medium, with a rotor which is rotatably arranged within this housing and which consists of a drive shaft which is rotatably mounted on one side of the housing about an axis of rotation and is fastened to the latter Disc, a plurality of axles supported at one end thereof, passing substantially through the center of respective conveyor blades, and an annular member located on the opposite side of the housing and supporting the other ends of the axles, and one within the rotor , however, eccentrically to the drive shaft on a pivot pin which can be fastened to the opposite side of the housing and which rotates the guide vanes in such a way that the gaps between adjacent conveyor blades, the housing and the guide part are full at each take the largest and smallest possible volume per revolution.
  • blowers which work according to the displacement method and whose operation is not possible without friction 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 piston machine of this type is known from US-A 1 385 084.
  • a disadvantage of this known machine is the fact that the conveyor blades are arranged in openings in a cylindrical component which represents a considerable flow resistance, that the rotor is essentially only supported on one side, and that the running properties of the annular component are unsatisfactory: and that the sealing of the side edges' of the conveyor blades that pass to the fixed sides of the housing, is difficult.
  • FR-A 975 985 further similar arrangements are shown in FR-A 975 985.
  • two essentially identical rotor disks are provided, so that the axes for the conveyor blades are supported uniformly.
  • the axes are arranged at the radially inner ends of the conveyor blades, so that these are subjected to considerable centrifugal and pressure forces.
  • the axes run through the center of the respective blades, but in this embodiment the rotor is only supported on one side.
  • the side edges of the conveyor blades run past fixed surfaces, which makes satisfactory sealing of the blade edges without loss of friction difficult.
  • the pivotably arranged rotating conveyor blades are steered by control levers provided in a control housing, which control a fixed cylindrical guide part which is attached eccentrically to the axis of rotation of the drive shaft.
  • the object of the invention is to eliminate the disadvantages of the arrangement mentioned at the outset and, in particular, to simplify the sealing of the conveying vanes with respect to the housing and to reduce the friction losses. At the same time, a mechanically stable arrangement is to be created.
  • annular component is designed in the form of a second disc, and that the two discs extend over the entire pivoting range of the conveyor blades.
  • the axes for the conveyor blades are evenly supported at both ends and the fact that the disks rotate with the rotor enables a simple and low-friction sealing of the side edges of the conveyor blades.
  • the advantageous effect of the freely rotatable guide part, against which the vanes lie tightly due to the centrifugal force and the delivery pressure, is maintained, which represents a rotating limitation of the gaps formed between adjacent delivery vanes and thereby directs the delivery vanes directly and safely.
  • the second disk is preferably mounted on a shaft provided on the journal and coaxial with the drive shaft.
  • the journal is also preferably rotatably arranged in the housing for adjustment about said axis of rotation.
  • the position of the guide part in the housing can be adjusted after loosening the fastening for the axle journal and by turning the same, whereby the smallest possible gap width can be achieved in each case.
  • the rotary piston blower consists of a housing 10 which has an inlet opening 11 and an outlet opening 12 for the working medium, the flow direction of which is indicated by the arrows 13.
  • a rotatably arranged rotor 14 which consists of a drive shaft 16 which is rotatably mounted on one side of the housing 10 about an axis of rotation 15, a disk 17 fastened to this, a plurality of disks 17 which are supported at one end by the disk 17, consists essentially of the center of the respective delivery blades 18 and 19 axes and an on the opposite side of the housing 10 located, the other ends of the axles supporting annular member in the form of a second disc 20.
  • a guide part 22 which is freely rotatably mounted on a journal 21 fastened to the opposite side of the housing 10.
  • the guide part 22 steers the conveyor blades 18 in such a way that they are located between adjacent conveyor blades, the housing and the interstices 23 located in the guide part take up the largest and the smallest possible volume with each full revolution. Since the drive shaft 16 of the rotor 14 and the journal 7 representing the axis of rotation of the cylindrical guide part 22 are offset from one another, air is conveyed in the direction of the arrow 13 shown in FIG. 1.
  • the two disks 17 and 20 extend over the entire swivel range of the conveyor blades.
  • the second disk 20 is mounted on a shaft 24 provided on the journal 21 and coaxial with the drive shaft 16.
  • the journal 21 is releasably attached to the housing by the nut 25.
  • the nut 25 is loosened and the journal is rotated about the axis of rotation 15.
  • the latter accordingly results in a rotating boundary surface of the interspaces 23 without any significant friction of the conveyor blades 18 on the guide part 22.
  • the weight and area distribution of the conveying blades 18 with respect to their respective axes 19 are selected such that the conveying blades are only slightly pressed against the cylindrical guide part 2 due to the centrifugal force, but due to the back pressure of the conveying medium.
  • the housing 10 has two sides 27 which are essentially square in plan view.
