Definitions

  • the invention relates to a rotary piston machine with a rotor, which has numerous chambers in which there are reciprocating flap pistons which delimit working spaces.
  • a rotary piston machine can either be designed as an expansion machine (motor) or as a compressor.
  • a rotary internal combustion engine is known, the rotor of which has several chambers. In each chamber there is a valve piston which swings back and forth around a valve shaft and delimits a working space. The volume of the work area is increased and decreased periodically when the valve piston moves.
  • the chamber in which the valve piston moves is divided by the valve piston into the working space and a dead space. The dead space is not available for work, so the Machine with low volume only has a low output.
  • Another disadvantage is that the inlet or outlet spaces of the stator must be arranged in the axial direction next to the rotor because there is no circumferential connection between the working spaces and the rotor. The openings must therefore be arranged in the front of the work area, which makes it difficult to seal and control the gas exchange precisely.
  • the invention has for its object to provide a rotary piston machine which has a favorable ratio of work performance and volume or work performance and weight and has a high efficiency.
  • each flap piston is driven in phase opposition to one another and each of the flap pistons separates two working spaces from one another in the same chamber. This prevents the creation of dead spaces behind the valve piston.
  • Each flap piston interacts with two different work rooms, in which opposite work processes are carried out. If compression occurs in one work area, the gas is pushed out of the other work area.
  • the rotary piston machine according to the invention can be designed as an effective and compact hydraulic motor or as a hydraulic pump.
  • An advantage is that the lengths to be sealed are relatively short, so that the problem of sealing the work spaces is reduced.
  • Another advantage is that the gearbox, which is required to control the flap piston, can be arranged coaxially inside the rotor, so that the entire machine has a compact design. The problem of lubricating the gearbox and the flap piston can also be solved in a simple manner.
  • the rotary piston machine shown is a compressor. However, the machine could also be operated as an expansion machine, with only the inlets and the outlets having to be exchanged. It is also possible to operate half of the machine as a compressor and the other half as an expansion machine (motor).
  • the machine has a cylindrical housing 10 which is closed by end walls 11, 12.
  • the rotor shaft 13 protrudes from an opening in the end wall 11 and is connected to a drive device when the machine is operated as a compressor.
  • Two stationary protruding from the opposite end wall 12 coaxial pipes 50 and 14 for the supply and discharge of lubricating oil.
  • the housing 10 rests on feet 15. On its peripheral surface there is an inlet 16 through which the fluid to be compressed is fed into the machine.
  • the compressed fluid exits at two outlets 17 and 18, which are connected to one another by external pipes 19. These pipes 19 lead to the main outlet 20th
  • the housing 10 is part of the stator 21, which also includes the tubes 50 and 14.
  • the tube 50 leads into the interior of the rotor 22.
  • This tube 50 carries a toothing 23 inside the machine, which forms the sun gear of a planetary gear.
  • the rotor 22 is mounted on the tube 50 via axial pressure bearings 24, 25 and needle bearings 26, 27.
  • the rotor 22 has an annular body 28 which is connected to a flange 29 of the rotor shaft 13 in the interior of the housing 10.
  • the ring body 28, which consists of several assembled parts, contains twelve evenly distributed over the circumference 30 chambers which are V-shaped and each form a segment of a circle with an angle of approximately 90 °.
  • a valve shaft 31 is supported near the inner end of each chamber 30, from which a valve piston 32 projects radially.
  • the flap pistons 32 are flat disks that move back and forth in the V-shaped chambers 30 between the one wall and the other wall by being pivoted about the axes of the flap shafts 31.
  • Each chamber 30 is circumferentially delimited by a wall 33 which has a circular contour and is at the same distance from the associated valve shaft 31 at all points.
  • the annular body 28 thus forms a ring of chambers 30, each of which widens radially outwards.
  • the flap shafts 31 and thus the flap pistons 32 are controlled by connecting rod drives 34.
  • the other end of the connecting rod 36 is mounted on a pin 37 which projects eccentrically from the axis 38 of the planet gear 39.
  • a planet gear 39 is assigned to each flap shaft 31.
  • the planet gear 39 is arranged between the valve shaft 31 and the sun gear 40 which is integrally formed on the tube 50.
  • the planet gears 39 mesh with the toothing 23 of the sun gear 40.
  • the ratio of the number of teeth of the sun gear 40 and the planet gear 39 is z: 1, where z is half the number of flap pistons, in the present case 6.
  • the planet gears 39 control the movements of the Flap piston 32 in synchronism with the rotation of the rotor 22.
  • two adjacent flap pistons 32 are driven in phase opposition to each other, i.e. if one of the valve pistons lies against the left end of its chamber, the adjacent valve piston lies against the right end of its chamber.
  • the back and forth movement of the flap piston 32 is achieved in that the planet gears 39 roll continuously on the toothing 23 of the sun gear 40.
  • the planet gear is rotated and it causes the reciprocating pivoting movement of the flap piston 32 via the connecting rod drive 34.
  • the walls 33 of the chambers 30 form an annular casing 41 which rotates with the other parts of the rotor 22.
  • This coat 41 which is the outer boundary of the rotor 22 forms, is closely enclosed by the housing 10.
  • the housing alternately has z inlet spaces A, C, D and z outlet spaces B, D, E distributed over the circumference, on the radially inward walls of which there are window-like openings 42.
  • Each pair of inlet and outlet windows together with two rotating chambers 30 along them form a separate compressor.
  • the z partial compressors can either be operated individually or connected in groups in parallel or in series. As shown in FIG. 2, the present example contains two identical two-stage compressors, the inlets and outlets of which are connected in parallel.
  • the inlet spaces A and C of the two first stages are connected to the inlet 16.
  • Rooms D are both outlets of the first and second tier inlets and are connected to rooms B, the two other outlets of the first tier.
  • the outlet spaces E of the two second stages are connected to the main outlet 20 via external lines 19.
  • the connections emerge on the one hand from FIG. 2 and on the other hand from FIG. 1.
  • the welds 45 indicate the meandering dividing line between the rooms.
  • the rooms A, B, C and .E each extend over a range of 30 ° of the circumference, ie over the same angular extent as a chamber 30.
  • the room D has the double angular extent as the other rooms, ie 60 °.
  • Adjacent chambers 30 are separated from one another by walls 43 which taper radially outwards. At the ends of the walls 43, however, the adjacent chambers are interconnected.
  • the jacket 41 has a radial, slot-like one opening 44, which runs along the openings 42, so that the two chambers are connected in sections via the openings 44 and 42 to the associated inlet and outlet spaces A, B, C, D, E.
  • the lubricating oil is supplied under pressure through the inlet port 50 'and introduced into the machine through the interior of the hollow tube 50.
  • the lubricating oil is distributed over the grooves 48 and bores 49 in the rotor 22 and is distributed to the connecting rod drives 34, the planet gears 39 and the chambers 30.
  • the lubricating oil then reaches the tubes 46, which run radially through the sun gear 40 and open into the tube 14.
  • the lubricating oil is discharged through the pipe 14.
  • the rotor shaft 13 is rotated so that the rotor 22 rotates in the direction of the arrow 47.
  • Gas is sucked into the chambers 30 via the openings 44 and 42 from the rooms A and C, which are connected to the inlet 16, and is subsequently compressed in a first stage.
  • the compressed gas is pushed into rooms B and D and subsequently sucked out of room D and further compressed in a second stage.
  • the gas compressed in this way in two stages is pushed out into the space E and reaches the outlet 17.
  • Each group of chambers 30 thus carries out a double two-stage compression.
  • Room D is twice the size of the other rooms because it combines the gases from the first two compression stages.
  • Each flap piston 32 delimits two working spaces, one of which widens and the other shrinks. In this way, each valve piston is used twice.
