Definitions
- the specified in claim 1,2 and 3 invention is based on this problem, a valve device consisting of compact and easy to manufacture rotary valves. It does not cause engine damage of the type that occurs with valves with camshafts if the controller does not work properly. It saves power for a drive and at the same time vibration, noise, and height of an internal combustion engine is reduced.
- Valve device can be produced by vinous and compact components.
- the invention relates to a rotary valve (Fig.l) having laterally at equal intervals symmetrically arranged openings.
- the rotary valve has a center of gravity, which lies on its axis of rotation.
- the pressure difference in an entire working cycle causes only a maximum of an axially resultant force along the axis of rotation, since inlet openings (or.
- Outlet openings of the cylinder also have a symmetrical arrangement. These factors prevent imbalance during operation of a rotary valve.
- the invention relates to a method for operating an internal combustion engine with a
- Valve device in which one or more rotary valves are used externally around the cylinder wall around and their axis of rotation is parallel to the cylinder axis ( Figure 4). It is possible to combine different openings of the cylinder and the rotary valve. For example: a) A cylinder has only outlet openings to an upper rotary valve and inlet openings to a lower valve (Fig. 8). Or b) a cylinder with paired inlet and outlet openings in only one (upper) rotary valve (Fig. 5, Fig.6).
- the inner wall of the rotary valve forms with the outer wall of the cylinder by their common identical running surface a sliding surface.
- This sliding surface is not exactly parallel to the axis of rotation, but slightly conical, so that the rotary valve by the different
- the opening angle of the valve or the cylinder can be increased or decreased by design to realize different opening times for the gas exchange.
- the number of openings of a rotary valve corresponds to the number of working cycles performed, in one full revolution (360 °). That is, the rotary valve has the factor 1 / n to the duty cycle of an engine, where n is the number of openings of a rotary valve.
- a rotary valve slows by a factor of 1 / (2 * n) to the crankshaft. Therefore, a rotary valve with 4 orifices in a four-stroke engine requires only one revolution when the crankshaft turns eight times (Fig.6).
- a phase shift of the inlet and outlet timing can be realized (for example by means of rotary valve drive by cylindrical gears with helical teeth).
