DE1062483B - Control slide for internal combustion engines with pistons rotating in an annular space - Google Patents

Description

The invention relates to a control slide for internal combustion engines with in an annular space rotating piston. In the case of these machines (see, for example, the German patents 819 606 and 904 694) the control slide divides the annulus into two zones, higher and lower Pressure. The piston and the slide axis cross each other perpendicularly in these machines, whereby compared to machines with parallel piston and slide axes, the advantage of better sealing is achieved.

Internal combustion engines with rotating pistons have already become known in which in or on a combustion chamber is formed on the control slide, but these are machines with piston and slide axes arranged parallel to one another. They are sealed between the subspaces of higher and lower pressure essentially through line contact with insufficient goodness.

To improve the seal, special intricate devices have been taken by but which makes the production more expensive and the operational reliability is reduced. With a well-known Machine with intersecting piston and slide axes is a stationary combustion chamber intended.

Operates m a known way, a single control slide at the same time with two annulus machines together, so, the one as a compressor, the other used as an expansion machine. The dimensions of the two annular spaces can be unequal.

For this purpose, according to the invention, in a manner known per se, with its axis of rotation, the The axis of rotation of the pistons is arranged to cross vertically and the annular spaces are different in two zones The pressure-dividing rotary valve itself creates the combustion chamber.

In the drawing is a section of a working simultaneously with two annular spaces, one Combustion chamber having control slide of an internal combustion engine shown.

The control slide 3, which rotates around the axis 1 and is mounted in the housing 2, simultaneously controls the two ring cylinders 4 and 5, whose runners 6 and 7 with the pistons 8 and 9 attached to them are in Rotate depending on the control slide.

The hollow peripheral wall 10 of the control slide passes through slots 11 in the walls of the annular spaces. She owns at least one Slot that allows the pistons 8, 9 to pass through at a given point in time.

the piston 8 acts here as a compressor, with z. B. the gas to be sealed in the direction of arrow 12 through the runner 6 enters through it in a known manner. With the front of the piston 8, this is compressed Gas simultaneously in the direction of arrow 13 through an opening 14 into a combustion chamber 15 serving The cavity of the control slide is pressed in.

During the rotation of the control slide by 180 ° z. B. via the hollow part 16 of the axis 1 fuel can be injected through a nozzle 18 into the combustion chamber 15 in the direction of the arrow 17.

In the position 14 ', which the opening 14 assumes after approximately 180 ° rotation, the flow out of it hot combustion gases from the combustion chamber and act in the direction of arrow 19 on the piston 9 in the Cylinder 5 of the other annular space machine acting as an expansion machine. From the back of the Piston 9, the exhaust gas is simultaneously pushed out in the direction of arrow 21 by rotor 7.

A gear (not shown), which ensures that the two rotors 6 and 7 run in the same direction, is connected to a gear 22 of the axis 1 so that the control slide 3 rotates in the desired time, ie at a speed corresponding to the speed of the rotors 6, 7 .
