Description

Cylinder rotary valve control The present invention relates to a revolving control valve cylinder, particularly for being used in a suction induction arrangement for an internal combustion polyclinic engine, with a suction induction manifold and individual suction tubes disposed one at a time. side of another flowing into a flange, said rotary valve cylinder being arranged in a longitudinal transverse bore of the individual suction tubes to open close the individual suction tubes. In the case of a suction induction arrangement according to EP B 0 177 794, individual suction tubes are grouped with a suction collecting tube in a unit, said induction tubes being flanged to said individual suction tubes as an additional component part. of aspiration, which is communicated on the one hand through a throttle butterfly part with the suction collection tube, and on the other side with the individual aspiration tubes. In each case, the second individual suction tubes can be closed or opened by means of butterflies which are mounted on respective shafts passing through the suction induction distributor. This arrangement of suction tubes known per se is relatively expensive in terms of their manufacture and causes problems in relation to a problem-free concurrent operation of the butterflies mounted in a tilting manner in the suction induction distributor with the second individual suction tubes , arranged elsewhere component. An arrangement of suction tubes for an internal combustion poly-cylinder engine is known from DE 42 44 504. In this case, the suction tube arrangement has a tubular shaping suction induction manifold, from which first individual suction tubes emerge, which extend in an arc-like manner around the suction induction manifold and lead towards the suction tubes. different cylinders of both rows of cylinders. Second individual suction tubes, shorter, also leave the suction induction distributor and open into the respective individual suction tubes. The suction induction distributor and the first and second individual suction tubes are formed in a component part formed in one piece, which has a longitudinal perforation. In said longitudinal perforation a rotary control valve cylinder is mounted, which has for each of the second individual suction tubes a through opening, which can be brought into alignment or out of alignment with the corresponding individual suction tube by means of a rotary movement of the control rotary valve cylinder. In practice it has been shown that such a rotating control cylinder cylinder causes swirling in the aspirated air. This swirling causes, in certain operating states of the motor, a decrease in the power of the internal combustion engine. Said windings are particularly disadvantageous in those areas where the rotary control valve cylinder extends transversely through all the suction ducts and causing in those suction ducts, which are not closed by means of the rotary control valve cylinder and that must be permanently open, a strong modification of the inner contour of the pipeline. The present invention therefore has the purpose of providing a rotary valve cylinder for control, with which the disadvantages mentioned above are overcome, which is simple to manufacture and which also does not disadvantageously affect the intake air flow. Said purpose is met inventively by means of a rotating control cylinder cylinder of the initially mentioned type, which is characterized in that said rotating control valve cylinder is constituted by a rotating control sleeve and a stationary core, the respective individual suction tubes being closed or opened by a rotary movement of the control sleeve. The advantage of the present invention lies in the fact that the rotating control valve cylinder is constituted by two component parts, that is to say that on the one hand it is constituted by a rotating control sleeve and on the other hand by a stationary core, taking place a closing and opening of the respective individual suction tube by means of a rotary movement of the control sleeve. The aim of the stationary core is to optimize the internal contour that influences the current in the individual suction tube. According to one embodiment of the present invention, the stationary core is connected by at least one end to the suction induction distributor. In order to fix the core, a plug-in connection or a screw connection is suitable as an example. In the region of the individual suction tubes, the support of the stationary core takes place via bearings or bearing areas, known indirectly through the rotating control sleeve. The rotating control sleeve, which extends through all the individual suction tubes, is provided with through openings in the corresponding areas of those individual suction tubes, which must not be closed, in particular in such a way that both in the closed position as well as in the open position the internal contour of the current of the individual open suction tube is not affected. An alternative solution of the proposed purpose provides that the revolving control cylinder cylinder is provided with butterflies, the system being constituted by the rotating control valve cylinder and the butterflies fixed by means of a fixing part in the induction distributor of aspiration. This particularly simple construction is characterized in that in this case the rotating control valve cylinder only causes a small resistance to the air flow in the individual suction pipes which do not close. The fastening part can be connected according to a particularly advantageous embodiment of the present invention with an intermediate flange of the suction pipe. Both the fixing part, as well as the combined rotary valve / control cylinder / butterflies can be pre-assembled, and can therefore be installed economically in a vacuum induction distributor. These and other features of further preferred developments of the present invention arise, in addition to the claims, also from the specification and the drawings, the individual characteristics may be materialized in each case by themselves or several in the form of subordinate combinations in the embodiment of the present invention and in other fields, and may represent advantageous embodiments, as well as susceptible to protection, for which protection is claimed. The present invention will be described below in more detail in connection with exemplary embodiments illustrated in the accompanying drawings, in which: Figure 1 illustrates a cut through an outlet flange of an induction manifold. Figure 2 illustrates a cut through an outlet flange of a suction induction distributor according to a second cutting plane. Figure 3 illustrates the output flange of a vacuum induction distribution with ducting in the closed state. Figure 4 illustrates the output flange of a suction induction distributor with ducting in the open state.

Figure 5 illustrates the output flange of a suction induction distribution with an interrupted duct, and open state. Figure 6 illustrates a rotary control valve with butterflies. Figure 7 illustrates the output flange of a butterfly induction induction manifold. To optimize the torque and the power of an internal combustion motor, cylinders of rotary control valves 10 are used, according to FIG. 1, arranged in the suction conduits, it being possible to vary the length of the rotary valve with said rotary valve cylinders. suction tube. In order to generate a high moment of rotation, the air of a long pipeline is tapped (channel of moment of rotation), while for high power and high number of revolutions the air of a short pipeline (power channeling) is sucked. The rotating control cylinder cylinder 10 has, in this case, the purpose of opening or closing the power channel 11. The outline of the free transverse section of the rotary control cylinder 10 corresponds to the cross section of the channeling of the suction tube, thus avoiding that the current falls off or is prevented. In the event that the rotating control cylinder cylinder 10 is to be used to cut the ducting of a suction pipe provided with two ducts, for example for a direct injection engine, it is necessary to open and close one of the ducts as shown in FIG. illustrated in figure 1, while the second neighboring channel, according to figure 2, is open in both positions d command. The inner contour 12 of the rotating control valve cylinder 10 has a disadvantageous influence on the current fillets, since in it swirls 13 are formed or the current fillets are detached. Figure 2 illustrates that the second channeling (turning moment pipeline 14) has an unfavorable inner contour at any position of the rotary control valve 10.

Figure 3 illustrates the possibility of sealing the power duct 11 by means of a rotating control valve cylinder 10, which is constituted by a mobile control sleeve 15 and a stationary core 16, in particular without making modifications to the internal contour of the individual suction tubes. In the drawing illustrated in the present case, the power duct 11 is closed by means of a corresponding position of the control sleeve 15. Figure 4 illustrates, on the contrary, the power duct 11 in the open state, the respective portions of the duct being superimposed on each other. control sleeve 15 and del-core 16 ^ Figure 5 illustrates the ducting of the moment of rotation 14, through which the core 16 also extends, as well as respective portions of the control sleeve 15. The sleeve 15 presents in the region of the duct of moment of rotation 14 both the through openings 18, 19, as well as the through openings 20, 21, which means that both in the closed position and also in the open position of the control sleeve 15 said duct of moment of rotation 14 is always in a state open and therefore no disturbances are generated in the contour of the free cross section of the pipe. Figure 6 illustrates a variant for improving the assembly of a rotating control valve cylinder with butterflies applied on it. In this case, the cylinder 22 of the rotary control valve extends through a flange 23, into which the respective individual suction tubes 24, 25, 26, 27, 28, 29 open, arranged side by side . The rotating control valve cylinder 22 is governed by the actuating device 30, which carries the same for closing the individual suction tubes 24, 26, 28 respectively butterflies 31, 32, 33, which are illustrated in FIG. present in open state. The rotating control valve cylinder is reduced in its cross section in the area of the individual suction tubes 25, 27, 29 so that the current is affected as little as possible in these ducts. The respective "butterflies 31-33 are fixed by way of example through a screw connection, a rivet connection on the rotary control valve cylinder 22. ___77 Figure 7 illustrates a cut through the individual suction tube 24 illustrated in Figure 6, the butterfly 31 being illustrated in a semi-open position. The assembly of the throttle body is substantially facilitated by the provision of a fastening part 34, on which the rotary control valve cylinder 22 can be preassembled, as well as the respective butterflies. the other component elements in the area of the flange 35 of the individual suction tubes A flange seal 36, which is embodied as a profiled cross-section seal, holds the fixing part 34 in the desired position and ensures in addition, the seal between the flange-shaped portion 35 or the entire flange structure of the suction pipe arrangement to be mounted on an internal combustion poly-cylinder engine, in fact there is also the possibility of providing an intermediate flange, which supports to the fixing part 34 and the rotating control valve cylinder This intermediate flange is also a pre-assembled building unit, which is an inse between the arrangement of suction tubes and the internal combustion poly-cylinder engine,
