Description

The present invention relates to a machine

  which, with appropriate equipment and adapta-

  tation of the basic design, can constitute an engine

  of the internal combustion type, a pump or a compressor.

  The basic element of the new machine comprises a circular envelope, in which is supported

  in a rotating manner a hollow cylindrical body whose sur-

  inner face of the wall surrounds a space delimited by cavities alternating with projecting parts

  Mvers the center of this space, each cavity being diametrically

  opposite to an inward projecting part. A solid cylindrical body is disposed within the said

  space, this cylindrical body being crossed transverse-

  on its axis by a bore in which a

  the piston can move back and forth.

  The defined space inside the cylindrical body

  that hollow is called, in what follows, "workspace", because in the operation of combustion engine

  internal, explosion and relaxation take place in this space.

  this, and cause the rotation of the hollow cylindrical body,

  so that a rotary motion can be taken on its

  (through which it is supported in rota-

  in the circular envelope). Similarly, the machine

  can be driven by applying a couple of entral-

  on the shaft, with the consequence that a fluid, for

  example of air or another gas, is compressed in the

  work pace. In pump operation, the fluid

  to be conveyed is sucked into the workspace and re-

  stepped out of this space. It is clear to those skilled in the art that a basic machine, such as the one described above, can perform the three functions when it has

  has been adapted to the desired function by known means.

  The basic element, indicated above, works as follows. The cavities, which are delimited in the vertical direction by the wall surface of the hollow cylindrical body and by an end face of the piston piece, plus portions of the solid cylindrical body, constitute

  rooms in which the operating phases take place

  machine, for example an explosion followed by a relaxation, or an aspiration followed by a compression or a pumping action. These chambers decrease and increase in volume alternately: the piston piece is caused to perform an axial movement in one direction or the other, each time an end face of the piston piece passes a protrusion or protuberance directed to

  inside the inner wall surface of the cymbal body

  hollow lindrique. Since, as already indicated, each cavity

  in the wall of the hollow body is located in front of a

  protruding towards the center of the hollow body, the movement

  alternative of the piston piece becomes possible. We suppose

  For example, a fuel mixture is injected into the working space, as defined above, and is ignited by means of a spark plug of the usual type in internal combustion engines. An explosion occurs, the mixture is burned, causing the body to rotate

  hollow cylindrical. Since there are several work spaces

  vail, ignition and explosion in a workspace

  are followed by the same phases in a workspace

  the consequence being that the hollow cylindrical body

  turns uniformly in the envelope. Of course, this movement

  rotation can be used in a known manner.

  It is clear to those skilled in the art that, similarly, the new machine can operate as a pump or compressor, once it has been suitably

adapted for this.

  The description above is that of the basic elements

  of the new machine. In what follows, a description is given of

  China or a moteu4built on this principle, but with

  the elements that allow it to work practically.

  The invention will be better understood in the light of

  the description of its embodiments, not limited to

  are shown in the accompanying drawings.

  Fig. 1 is an axial section of a machine according to the invention. Fig. 2 is a horizontal section along the line

II-II of Figure 1.

  Fig. 3 is a section along line III-III of

Figure 1.

  Fig. 4 is an axial section through the workpiece

  piston shape, indicated above.

  Fig. 5, 6, 7 and 8 are horizontal sections

  similar to Figure 2, at different stages of the

  the cuts are made at different levels.

  Fig. 9 represents a variant embodiment of

  the rotating machine according to the invention.

  In the casing or housing 1 is rotatably supported

  a shaft 2 secured to a cylindrical body 2 '. In practice

  This part of the machine can be composed of several

  some elements assembled together but which may

  must be regarded as interdependent with regard to the operation.

  As shown in FIG. 2, the wall

  body 2 'has three cavities which can be compared

  rer, sectional views transverse to axis 2, a clover.

  As already indicated, a protrusion or projection is located diametrically opposed to each cavity. The cavities, which are crescent-shaped, are designated by the letters a, b, c while the respective opposing protuberances

  are designated by a ', b', c '. At the top of each protuber

  are provided with gaskets 11 for sealing

  required between the contacting faces of the protuberances a ', b', c 'and a body (described below), which moves by

compared to these.

  As shown in FIGS. 1 and 2, in the

- 2501291

  cylindrical body 2 'are disposed, at two levels and at a rate of one at each level, solid cylindrical bodies which are traversed by a bore 101 perpendicular to the shaft 2. A body 3 is housed slidably in the bore 101.The body 3 is traversed by a light 25,

  in which the tree passes.

  mity of the body 3 are retained parts 4 in the form of pistons.

  tone, one in each face.

  Each of these parts 4 comprises, from one of its circular end faces, a short shaft 4 'on which is keyed a gear wheel 5. These wheels meshing

  with an internal toothing 102 secured to the body 2 '(fi

  Figure 3). In accordance with the contour of the inner wall of the body 2, the toothing 102 has a configuration in the form of

Clover.

  FIGS. 1 and 2 show that the two bodies 3, placed one below the other, are also

  shifted relative to each other in their long-term direction

  gitudinale. As indicated above, the interior space defined by the body 2 'is the working space and, in the case of an adaptation by internal combustion engine, the compression,

  the explosion and expansion of the fuel mixture

  kill in cavities a, b, c in the shape of a crescent. In

  Accordingly, inlet ports 9 are provided in each

  that cavity and orifices 11 allow the exit of each

  than cavity. Other passages 12 communicate the space

  from the first level to the second level.

  These passages 12 are controlled by shutters or valves.

  13. A spark plug or fuel injector

ble can be placed at 14.

  Figure 4 illustrates a preferred form of

  truction of the body 4. It is composed of two parts

  15 and 18, in the form of a bowl, each having on the

  inner bottom of the bowl, a boss 15 ', 18' respectively.

  Both bosses are aligned with each other. Around

  aligned bosses 15 ', 18' is arranged a helical spring

  coldal 16 which tends to bring the two parties and the

  thus keeps tightly assembled. An annular pad

  17 provides sealing between the parts 15, 18. The machine according to the invention functions as

  described below, with reference to FIGS. 5 to 8.

  the machine is started by means of a device

  tif of usual launch, that is to say that we turn the

  cylinder 2 ', for example in the opposite direction to the

  the clockwise, and at the same time is injected a mixture of air and fuel, for example in the chamber c-shaped crescent, through the inlet port 9. The fuel mixture is first compressed in b and explodes at the desired moment. The compression results from the movement of the body 2 'counterclockwise, which causes the volume decrease of the chamber t. This movement is

  possible because the body 3 can fade and move

  To the right in Figure 5. When the boss is reached by the piston piece on the left, the body

  3 is pushed to the right. If we then inject

  fuel in the chamber a, compression occurs, followed by explosion and expansion, which

  tends to rotate the cylindrical body 2 and to maintain

  rotate. The process is repeated in room c,

And so on.

  However, as already indicated, bodies 3 can be superimposed on each other, as represented in fact in FIG. 1. Therefore, preferably, the stages of compression, explosion and relaxation can occur.

  in the different rooms of the groups superimposed. AIN-

  if, the fuel can be injected into one of the chambers

  for example on the right side of the lower group of Figure 1, be partially compressed in this chamber

  and transferred through line 12 (see FIG. 1 and FIGS.

  5 to 8) in an upper chamber where compression is complete and the explosion occurs. The valve 13 prevents the combustion gas from returning to a lower chamber. The outlets through which exhaust gases escape are visible in FIGS. 1 to 8.

  Referring now to Figure 9 which represents

  an alternative embodiment of the invention. This provision

  also includes housing 1, shaft 2, body 2 'and body 100. It is assumed that in the construction of FIG. 9, body 100 rotates while body 2

is fixed.

  In the three protuberances a ', b', it is

  views of the cylindrical chambers 110, 111, 112 respectively.

  The chamber 110 is connected with the space of the cavity b by a passage 114, the chamber 111 to the cavity c by a passage

  114 and the chamber 112 to the cavity has by a passage 114. Of

  on the other hand, a passage 116 connects the cavity a to the chamber 110,

  a passage 117 connects the chamber 111 to the cavity b and a step

  wise 118 goes from the cavity c to the chamber 112.

  This device works according to the same principle

  than the preceding embodiments, with the modification

below.

  It is assumed, as before, that piece 100

  turn clockwise, the compres-

  sion is thus carried out in the part of the cavity b which is at the top part in FIG. 9 and it is

  transmits through the passage 117 in the room 111. If we inject

  then fuel in this chamber, the explosion takes place as soon as the pressure is high enough, that is to say that

  the engine operates on the principle of the diesel engine. always

  sometimes, a spark plug can be placed in the wall

  of the body 2 and the engine can operate in Otto engine. AT-

  near the explosion, the gases that relax penetrate through the passage 114 into the cavity where the operation is renewed and

  is repeated again in cavity a and chamber 110.

  It is understood that modifications of detail may be made in the form and construction of the device according to the invention without departing from the scope

of it.
