Definitions

  • the present invention relates to a displacement machine for compressible media according to the preamble of the claim 1.
  • a generic displacement machine based on the spiral principle is known for example from DE-A-42 03 346.
  • Machines of this type are characterized by pulsations of relatively low amplitude promotion of for example from air or an air-fuel mixture existing gaseous working medium and can therefore also for charging internal combustion engines Advantage.
  • a positive displacement machine along spiral conveying spaces between also spirally formed, acting as a displacer Strips and the two cylinder walls of the delivery rooms due to different curvature of the spiral shape, about crescent-shaped work chambers included, which themselves from an inlet for the work equipment through the Move delivery rooms through to an outlet, whereby their volume is constantly decreasing and the pressure of the Working medium is increased accordingly.
  • each ledge has outer faces when viewed in the radial direction and inner sealing surfaces, which at the beginning on the inlet side of the strips start and at the outlet end the last end.
  • Each of the strips thus forms together with the corresponding cylinder wall of the assigned delivery chamber a working chamber every 180 ° angle of rotation of the drive.
  • CH Patent Specification No. 673 679 also shows in detail the way, as in displacement machines after the Spiral principle the working chambers by a circular movement the one attached to the disc of the displacer Last in cooperation with the spiral conveyor rooms arise in the housing.
  • Such work chambers will be both through the inside of the bar and through the Outside limited.
  • Typical of this arrangement is that from a spiral ledge as it progresses Rotary movement of the eccentric drive and guide shafts a new working chamber every 180 ° is formed, or the filling process of a working chamber is completed.
  • DE-A-41 33 429 discloses a possibility of symmetrical Disrupt sequence of suction and delivery cycles.
  • the solution shown therein assumes that the funding areas in the Housing and the spiral strips on the disc of the To shift the rotor polarly so that the Sequence of suction and delivery cycles no longer uniform is. Furthermore, the strips are on the pane the runner no longer mirror-symmetrical on both sides arranged the disc, but again angular with respect the axis of rotation of the eccentric drive shaft against each other postponed. This creates the desired irregularity the suction and delivery cycles of the machine elevated.
  • the displacement machine according to the invention has given Speed of the drive an increased periodicity of Suction and delivery cycles. Show any pulsations therefore only very small amplitudes.
  • the present invention leaves a completely symmetrical one Arrangement of the strips on the pane too what helps the pulsations as well as tilting moments on the Prevent or reduce displacers.
  • a displacer of a displacement machine which is arranged as a rotor in a housing 7 ''.
  • a disc 2 of the displacer 1 On both sides of a disc 2 of the displacer 1 are each two offset by at least approximately 180 ° to one another, spiral-shaped displacer arranged; it are strips 3, 3 'which are perpendicular to the Disk 2 are held.
  • the spirals themselves are shown in the Example of several, adjoining Arcs formed.
  • 4 denotes a hub, with which the disc 2 is mounted on a bearing 22 is.
  • the bearing 22 itself sits on an eccentric disk 23, which in turn is part of a drive shaft 24 is.
  • the eccentricity e (Fig. 2) of the eccentric 23 on the drive shaft 24 corresponds to that of the eccentric bolt 26 the guide shaft 27.
  • Are the outlet side of the strips 3, 3 ' 2 openings 6 are present in the disk, so that the working medium get from one side of the disc to the other can, for example, through a central outlet 13 to be led away, the one on the right in Fig. 1 shown housing part 7 'of the housing 7' 'is formed.
  • a pulley is designated, which is rotatably with the drive shaft 24 is connected.
  • the drive shaft 24 is in one by means of a bearing 58 1 on the left in FIG. 1 and by means of of a bearing 62 in the housing part 7 '. Through the pulley 19 becomes the displacer 1 via the drive shaft 24 driven. On the also mounted on the housing part 7 '' Guide shaft 27 is also fixed against rotation Toothed belt pulley 10 which by means of a toothed belt 16 for angularly accurate synchronous drive of the guide shaft 27 with the drive shaft 24 coupled to the toothed belt pulley 9 is. Through the drive designed in this way leads the displacer 1 a rotating, rotation-free in machine operation Sliding movement off. 40, 40 'are centrifugal weights, which are attached to the drive shaft 24. They serve to compensate for the displacer 1 during Machine operation acting on the eccentric 23 Centrifugal force.
  • FIG. 2 is the housing part shown on the left in Fig. 1 7 'of the two axially abutting housing parts 7, 7 'assembled, via mounting eyes 8 for receiving of screw connections 8 'interconnected housing 7 '' shown.
  • 11 and 11 ' respectively denote two Conveyor spaces offset by 180 °, which according to Art a spiral slot in each of the two housing parts 7, 7 'are incorporated. They always run on the radially outer circumference of the spiral in the housing 7 '' arranged inlet 12, 12 'to the centrally arranged, two delivery rooms 11, 11 'common outlet 13.
  • the displacer 1 is better known Design shown separately.
  • they are radial outer and radially inner sealing surfaces 30, 30 'or 31, 31 'forming sections of the strips 3, 3', which on the outer cylinder walls 14, 14 'and inner Cylinder walls 15, 15 'of the machined into the housing parts 7, 7' Funding rooms 11, 11 'for formation and displacement approach the working chambers, entered in bold.
  • the inlet side Beginning 32, 33 and the outlet end 34, 35 of the inner sealing surfaces 31, 31 'and outer sealing surfaces 30, 30 ' in the direction of movement of the medium and thus viewed in the circumferential direction, for example opposite.
  • the Crosspieces 17, 17 'towards beads protruding inwards 36, which are intended to begin with 32 of the concerned to cooperate with the outer sealing surface 30 or 30 '.
  • FIG. 5a shows the displacer 1 in a first position, in the outer spiral sealing surface 30 of the strip 3 a first working chamber 41, which is indicated by hatching is included.
  • the angle of rotation of the drive is next to the housing 7 '' based on the position of the center of rotation 59 of the drive shaft 24 and the center axis 61 of the eccentric disk 23 shown.
  • FIG. 5b shows the displacer 1 in a second position which is the drive with respect to that shown in Fig. 5a Position rotated clockwise by approximately 90 ° Has.
  • the working chamber 41 is in this position open on the outlet side and the inner spiral sealing surface 31 the bar 3 closes a second working chamber 42, the also hatched is a.
  • This Working chamber 42 has at least approximately the same Size as the working chamber 41.
  • FIGS. 5c and 5d show the outside Sealing surface 30 'or inner sealing surface 31' included Working chamber 43 and 44, the further rotation of the drive by about 90 ° angle of rotation be formed.
  • FIGS. 5a to 5d it can thus be seen that according to the invention on each side of the disc 2 of the rotor 1 at intervals of approximately 90 ° angle of rotation of the drive in each case a working chamber 41, 42, 43, 44 included becomes.
  • the strips 3, 3 ' are opposite the disc 2 of the Displacer 1 arranged symmetrically and the beginnings 32, 33 and ends 34, 35 of the sealing surfaces 30, 30 ', 31, 31' so that the machine operation per revolution of the The resulting working chambers are about the same size are.
