Definitions
- the invention relates to a Rotary piston device, machine or pump, having a piston located in the interior of a Housing moved and enclosed spaces enlarged and reduced (Meyers Grosses Taschenlexikon, 5 edition 1995, volume 19, page 7) A Roots machine with a disc-like piston disc is known (DE 588 285 C).
- rotation also understood to mean that back and forth Swiveling movements are possible, so not complete Revolutions are carried out in succession, but e.g. also back and forth swinging movements.
- the rotary piston device described below differs from the known constructions by Use of only a few parts (pistons and rotary cylinders) and by rotation around the center of mass (without eccentricity). This leads to good efficiencies and allows simple and thus inexpensive constructions. Like others Piston machines can do without valves.
- Piston engines are generally based on the Operating principle that a relative to an envelope movable piston, an enclosed volume increased or reduced.
- the piston should have this volume as much as possible limit tightly. Now you can easily convince yourself that a simple rotation of a piston around an axis leads rotationally symmetrical structures and none Changes in volume generated in any chambers. On The trick is the Wankel engine, which uses a gearbox an oscillation of the piston in a special enveloping Form leads to a change in volume in the chambers. there the piston does not rotate around the center of mass!
- Rotary piston is that of Paul Schatz found oloid (CH 500 000 C).
- the oloid is a body that passes through developable control areas is formed. You can look at him Think emerged when you round up two round beer mats radially cut in half and put together so that the Cross the lid. The periphery of one goes Cover through the center of each other. You put it this structure on a flat plate, e.g. a table like that each of the two lids touches the plate at one point. This applies to every possible position of the two lids.
- the Straight line between the support points Line straight of the oloid (compare figures according to Fig. 1).
- the oloid In addition to its aesthetics, the oloid has some Symmetry properties that are of interest here. You turn the oloid 90 ° around its longitudinal axis, so it takes a position which corresponds to a rotation of 180 ° around the vertical axis!
- the shape enveloping the oloid must be chosen so that the two rotating chambers are separated by the piston. Furthermore, the rotation of the oloid about the longitudinal axis is intended to pass through the shell is imprinted on the oloid. In addition, present you look again at the shape of the shell that arises when the oloid is rotated through 180 ° about the vertical axis and at the same time by 90 ° around the longitudinal axis. The changes Direction of rotation around the longitudinal axis creates a different shape the shell! If you think through the situation more closely, it poses one finds that with the direction of rotation maintained around the Longitudinal axis the "first" 180 ° rotation around the vertical axis describe a different form of envelope than the "second", i.e.
- the shape of the The shell depends on the shape of the oloid and the Function ⁇ (Fig. 4). Parts of the shell are covered by the circular edges of the oloid and parts through the Generated straight lines. Problem areas occur around the Vertical axis and at the pointed end of the cut. A Reduction or elimination of problem areas in the area the vertical axis can be reached by looking at the generating circles of the oloid pulls apart (opening angle 45 °) and additionally the oloid from a ball around the center can penetrate (Fig. 3).
- the ball and its shell are part of the shell a separation of the two chambers in the area around the Vertical axis.
- Suction pump offers e.g. the rotary piston as an anchor to train an electrical machine and the cover with to provide a corresponding winding. With that you would have a pump with only one moving part. Except Frictional losses result in no further losses from e.g. Mass redirection, as the vibration energy for the vibration taken about the longitudinal axis of the movement about the vertical axis and this is also fed again. The piston will so perform a pulsating movement.
- the basis of the preferred embodiment of the invention lying piston is not identical to that of Paul Schatz found form. However, it exhibits its symmetry properties on. Changes exist in the distance of the generating circles, in the alternative penetration with a ball in the center and a (slight) deformation of the oloid shell. Further changes are conceivable, e.g. Replace the circles of the oloid by ellipses. All of these changes touch not the symmetry properties.
- a particular problem with the rotary piston machine according to The invention consists in the transmission of mechanical forces on the piston or the oloid. Because there is not Possibility of simply pulling out an axis Way to accomplish a power transmission.
- the basis of the construction is the special one Geometry of the piston with its special Symmetry properties.
- the piston Put the piston with his Longitudinal axis on the X axis and with its vertical axis on the Y axis, so are the XY plane and the XZ plane Planes of symmetry, but not the YZ plane.
- the YZ level becomes the plane of symmetry when a piston half turns 90 ° the longitudinal axis is rotated!
- the piston 12 is inside two housing halves 10 ⁇ m its two axes rotatably.
- a bearing tread 11 is attached, which with the Longitudinal axis of the rotary piston 12 is firmly connected.
- the Rotary piston 12 is in the journal 15 about the longitudinal axis stored and can follow the shell freely.
- the tread is provided with a ring gear on the outside which Housing attached bevel gear 13 the movement of the piston transmits to the outside.
- 16 and 17 are inlet and outlet for a medium referred to by this the piston 12 or the bevel gear 13 to drive.
- the piston is essentially two spaced apart and a common surface having geometric surface elements or geometric bodies. It can be Ellipses or other shapes, but also around cylinders or cuboid act that one around one, two or three axes can rotate.
- the one formed by the shells Interior of the housing has essentially one of the Spherical shape derived from rotation (uniaxial, biaxial or multiaxial) of the piston thus formed has arisen, essentially in Equatorial plane area diametrically opposite each other and perpendicular to and distal from the plane of symmetry of the Interior at least one fluid inlet and outlet is arranged.
- the design with a ball in the center also allows more than attach two side wings to the ball (fan arrangement), that of the shell when rotating around the follow longitudinal axes.
- the rotary piston machine as an internal combustion engine
