Definitions
- the invention relates to a rotary slide control for Internal combustion engines and piston pumps with one Cylinder head, in which a rotationally symmetrical, dome-shaped, with one coupled with a drive Rotary valve is arranged rotatable about the cylinder axis and in the cylinder head at least one intake port and at least one outlet channel provided, and in Rotary slide valve one with the inlet channel and the outlet channel Corresponding control opening are provided, in which in the area of the inlet duct and the outlet duct at least on the side of the cylinder facing the A freely rotatable sealing ring is arranged, the rotary valve is driven in the middle and the Cylinder head and the cylinder on both sides of the Rotary valve are provided with cooling channels.
- the technical problem underlying the invention therefore consists in the known known Rotary valve control with regard to their Reliability, resilience, service life and Improve thrift.
- the rotatable Seals have a multiple function. Because now regardless of the rotation of the rotary valve mechanically or preferably hydraulically driven they are also lubricated and cooled.
- the sealing rings on the outside i.e. the one on the cylinder opposite side of the rotary valve not only seal the Rotary valve from the inlet and outlet channels, but they also act as thrust bearings around which the Pistons generated and acting on the rotary valve Dampen compressive forces.
- the sealing rings which act as axial bearings, also prevent a possible vibration of the rotary valve when changing the load during the operation of the device. This allows the wall thickness of the rotary valve at the same time reduce so that less heat is stored in it and the momentum caused by their mass be reduced.
- the suspension unit can also be fitted with in their spring characteristics of controllable springs to be - for example in one application Internal combustion engine - the engine characteristics to the Adjust requirements and for example a higher one To be able to achieve torque.
- Fig. 1 are the cylinder 7 with the arranged therein Recognize piston 9 and the cylinder head 8.
- cylinder head 8 and cylinder 7 have cavities 10 for receiving Coolant.
- the rotary valve 1 provided with a collar 11 arranged.
- the upper end of the collar 11 is non-positively provided with a drive wheel 12.
- the Middle part of the cylinder head 8 has a cup-shaped Well 13 on, in the bottom of an opening for the Inclusion of an ignition device, for example one Spark plug is provided.
- the suspension device 16 switched on.
- the exhaust port 6 can be seen in the cylinder head 8, which compared to the rotary valve 1 by rotatable Sealing rings 2 and 3 are sealed. Sealing rings 14 and 15 are also used to seal the collar 11 against the Cylinder 7 and the cylinder head 8 are provided.
- Fig. 1 is in the area of the outer Edge of the rotary valve 1 in the cylinder head 8 circumferential channel available, which via the opening 17th communicates with the outside atmosphere.
- the sealing rings 3 are also axial bearings trained so that the compression of the Damp the rotary valve acting forces. If one during the operation of the device controllable Suspension device 16 is used, the Ejection clock of the device can be influenced the operating characteristics adapted and for example a higher torque can be achieved.
- FIG. 2 shows the relative position in a snapshot the opening 4 in the rotary valve 1 opposite the inlet channel 5 and the exhaust port 6 in the cylinder head 8 at one certain rotational position of the rotary valve 1.
- the rotary valve 1 is arranged in the center of the cylinder head. Due to the coolant contained in the cavities 10 Cylinder 7 and cylinder head 8 and thus also the Rotary valve 1 cooled.
- the facing the rotary valve 1 Surfaces of the cylinder head 8 and the cylinder 7 are on adapted the spherical shape of the rotary valve 1.
- the rotating sealing rings 2 and 3 which - as shown - installed on both sides of the inlet and outlet duct for the required sealing during operation.
- the degree of compression is not caused by a glowing valve limited.
- the flow in the inlet and outlet channels becomes by approx. 40% compared to valve actuated inputs and Exhaust openings improved.
- One by valve springs power loss caused does not occur.
- the speed limit is shifted to higher speeds. The The engine runs more smoothly and quietly. The better one Utilization of the fuel leads to protection of the Environment.
