Abstract

Positive displacement machines as internal combustion engines, comprising the compressor (1), the combustion chamber (9), the engine (2) and a variable-speed drive (13), inserted between compressor and engine, designed on a simple operating principle so that it can be used in place of piston engines or of gas turbines. The efficiency of the machine is greater than that of piston engines and of turbines due to pulsed combustion and also to the fact that no balancing of masses is necessary on the moving parts. The operating principle is characterised in that a number of spherical cup rings (3) are inserted into one another, that, together with these, spherical cone-shaped, undulatory, opposing working chambers (8) are formed by a helical shaft (4), the volume of which chambers varies, migrating inwards or outwards with the rotation of the shaft. The spherical cup rings perform a tumbling movement. The shaft has a lefthand thread on one side and righthand thread on the opposite side. Sealing of the working chambers is achieved by sealing rings (7) in the spherical cups and by engagement in toothing-like depressions (5) of the housing (6). The pulsed combustion in the combustion chamber with its ignition device (12) and the injection nozzle (11) allows the temperature of all components to be controlled. The arrangement of the variable-speed drive between compressor and engine permits control of the combustion chamber pressure and a speed control ... Original abstract incomplete. <IMAGE>

Zu den hervorragenden Merkmalen zählen:The outstanding features include:

  • - die Kugelschalenabschnitte, die von einer Welle so bewegt wer­ den, daß sich bei der Rotation der Welle immer größer bzw im­ mer kleiner werdende abgeschlossene Arbeitsräume bilden,- The spherical shell sections that are moved by a shaft the that with the rotation of the shaft always larger or in form smaller and smaller working spaces,
  • - die Arbeitsräume, die soweit als nötig, durch die Kühlung des Gehäuses gekühlt werden können,- The work rooms, as far as necessary, by cooling the Housing can be cooled
  • - die Verbindung des Kompressors mit dem Motor zu einer Bauein­ heit,- The connection of the compressor with the motor to a building Ness,
  • - die Anordnung, die Bauweise und der Betrieb der Pulsations­ brennkammer, wodurch erreicht wird, daß durch den Motor ein Arbeitsmedium mit hohen Temperaturdifferenzen strömt, somit der Wirkungsgrad erheblich gesteigert und die Bauteiltempe­ raturen niedrig gehalten werden,- the arrangement, construction and operation of the pulsations combustion chamber, which is achieved by the engine Working medium with high temperature differences flows, therefore the efficiency increased significantly and the component temperature temperatures are kept low,
  • - die mechanische Koppelung des Kompressors mit dem Motor mittels Regelgetriebes, was eine Drehmoment- und eine Drehzahlver­ änderung an der Abtriebswelle wesentlich erleichtert,- The mechanical coupling of the compressor to the engine by means of Control gear, what a torque and a speed ver Modification of the output shaft is much easier,
  • - der Einsatz eines Prozeßrechners zum Vergleich der Eingangs­ signale mit den Sollwerten für die Regelung der Maschine.- The use of a process computer to compare the input signals with the setpoints for controlling the machine.

Die hervorragenden Merkmale zeigen dieKomplexität der Zusammen­ hänge zwischen den mechanischen Bauteilen und des Arbeitspro­ zesses, sie können nicht alle Merkmale dieser Maschine charakte­ risieren.The excellent features show the complexity of the together hang between the mechanical components and the work pro zesses, you cannot characterize all the characteristics of this machine rize.
