Abstract

Owing to the compression and expansion phase produced in a rotation of the slide, the entire assembly is a two-stroke heat engine. Due to the good blocking function between the differential pressures, a displacement effect is achieved in the rotation, making the same assembly suitable for drive functions and for compression functions. Design advantages 1.) Simple construction with few moving parts. 2.) Acceleration of the masses in one direction. 3.) Thrust power in one direction. 4.) Rotating drum provides the function for blocking element and charging element, and output, cooling, lubrication and flywheel. 5.) Low residual gas retention and hence good fresh-gas charging, due to small clearance. 6.) Good mixing of the charge, and heat division into reaction heat and compression heat by virtue of the two assemblies.

Description

Generic term

Rotary piston motor that can be swiveled by a slider mounted in a rotating drum, the through a spatially fixed, free running slotted cylinder core and thus pushes creates a volume-changing spatial expansion, is for drive tasks as well as for compression suitable for gases.  

Description mechanics and function

The locking slide ( 2 ), which can be pivoted on one side within a drum ( 1 ), pushes the excess length resulting from the eccentricity into the slotted cylinder core ( 4 ) enclosed by the cylinder ring ( 3 ), the main task being performed by the barrier between the pressure differences.

The figure shown in Fig. III shows the cylinder core provided with slideways ( 4 ) which is evenly provided on the outer surface with holes which are equipped with compression springs and balls, so that the cylinder ring ( 3 ) pushed over the cylinder core with little play in a uniform manner Distance to the cylinder core ( 4 ) floats.

Only by turning the eccentrically designed bearing bush ( 5 ) for the cylinder core ( 4 ) is a constantly even pressure on the drum ( 1 ) achieved.

The side seal is provided by the split cylinder ring ( 3 ), whereby the balls in the middle row are pushed into the conical cutting shaft by the spring pressure.

The illustration in Fig. IV shows the likewise split, spring-loaded gate valve ( 2 ) whose gate valve suspension is cup-shaped to enable installation within a thin-walled drum ( 1 ).

The agregates Fig. I mounted on both sides of the same design, but with different functions, are screwed together offset in the middle to keep the load path short.

Fig. V at the same time, the loading valve ( 7 ) and its start and end of charge are controlled by the position of the guide rollers ( 8 ) through the driven belt placed in the middle.

Fig. VI the cooling is achieved through uniformly distributed in the drum wall through ventilation channels ( 14 ) which are cut in the area of the output.

Fig. VIII now a fixed area on the curled blade ring (15) causes rotation of the drum at (1) a slingshot effect, which produces a steady stream of air through the ventilation channels (14).

The lubricating oil is fed through a bearing channel in the feed channel ( 16 ) located in the cylinder core, distributed over oil channels ( 17 ) at the slide gate suspension and collected and separated by a fixed trough-shaped lamellar ring ( 6 ).

Through the inlet channel (9) of the charge compressor (10) is supplied with circulation of the blocking slide (2) on the suction side continuously a mixture, during the same time held on the pressure side of the locking slide (2) has a compression which at matching pressure ratio by the charging valve (7 ) is reloaded in the correct period.

At the end of the charge, after the loading valve ( 7 ) has closed, the charge enclosed in the motor ( 11 ) is ignited, with expansion on one side of the locking slide and, at the same time, being pushed out or flung through the exhaust duct ( 12 ) on the other side of the locking slide.

Criticism of the state of the art Reciprocating engine

When cranking the accelerated masses continuously in the opposite direction again is also redirected during a crank circulation Piston speed changed continuously.

task

The task is accelerated masses move evenly in the same direction.

solution

Due to the good shut-off devices between the pressure-neutral Cylinder core and the rotating drum creates a volume-changing room design which in the case of expansion is only an expansion into one Allows direction and thus a uniformly continuous Rotary motion generated.

Claims (2)

Characterized in that the locking function between the pressure differences through the divided cylinder ring , which floats with little play on the cylinder core evenly occupied with compression springs and balls and thus produces a seal in the radial as well as in the axial direction and causes the distribution of the lubricant. In addition, the also divided locking slide with the locking slide suspension, which due to the bowl-shaped design within a relatively thin-walled drum finds an important locking function. Characterized in that two units of the same type, which differ due to other tasks only by different inlet and outlet channels, are screwed together in the middle to achieve short load paths.
In addition to the stripping section, the center also houses the blade ring for cooling and oil separation, the charging valve with control device and the spark plug.
