Definitions

  • the present invention relates to media mass control elements for controlling flow masses of fluid media.
  • the invention relates in particular to systems for the mass flow control of gaseous or liquid media.
  • the present invention relates to air mass controls in internal combustion engines (internal combustion engines) for mobile and stationary applications.
  • Ball valves for controlling flow masses of gaseous or liquid media have been known for a long time. Flap systems such as throttle flaps, which have a continuous axis for actuating the flaps or other actuating elements, are currently frequently used in internal combustion engines of motor vehicles. These axes have several disadvantages. The flaps form a flow resistance even in the open position. The axes cause a so-called "wave shadow" and thus reduce the possible flow volume, disrupt the media flow and lead to turbulence and other, often undesirable physical effects. In addition, the axes of the flaps must be sealed with seals so that no impermissibly large leaks or Secondary air rates arise which have a negative impact on tax quality.
  • the invention is based on the object of providing a media mass control element which makes it possible to generate a pulsed or pulse-charged air stream for the introduction into the combustion chambers of a Brerin engine.

  • the invention is based on the object of providing an intake device for internal combustion engines which uses the advantages of a media mass control element according to the invention.
  • a media mass control element having a housing and a shut-off element.
  • the housing has an inlet opening and an outlet opening.
  • the shut-off element is rotatably mounted in the housing and has an essentially spherical geometry with a through opening.
  • the shut-off element has an axis of rotation defined by a passage in the housing, about which it can be rotated mechanically. In at least one position of the shut-off element, the entrance opening and the through opening and the through opening and the exit opening are respectively aligned.

  • the media mass control element is characterized in that the shut-off element has an essentially tubular section that defines the through opening.
  • the tubular section is provided with at least one rib.
  • the rib or the ribs can be designed as transverse ribs, longitudinal ribs (stringers) and / or oblique ribs, full or partial ribs.
  • the tubular section and the ribs have essentially the same wall thickness.
  • the edges of the ends of the section and the edge of the at least one rib preferably lie on the surface of an essentially spherical body of revolution.
  • shut-off element in one embodiment could also be described as a shut-off body of a ball valve, which was provided with a rib structure by milling on the outer surface of the ball.

  • Such a design is not yet known in metallic embodiments for ball valves.
  • the shut-off element described here has the same wall thicknesses at every point (system with the same wall thicknesses as possible), and thus avoids the disadvantages such as warpage and formation of voids that occur with a shut-off element made of all-plastic.
  • the ribs and stringers allow the outer contour of a sphere to be maintained without the mass and volume of a sphere having to be present. In this way, the smallest possible changes in wall thickness are achieved and also stresses caused by the geometry are avoided.
  • the shut-off element according to the invention only comprises the section delimiting the passage and a rib which, when the shut-off element is closed, covers or closes a remaining gap between the section and the housing.
  • the rib can preferably be designed such that it always bears against the housing when the shut-off element is actuated and does not come into the region of the inlet or outlet opening. Thus, the rib that seals the gap between the tubular portion and the housing cannot catch on the edges of the inlet or outlet opening.
  • the advantages of the ribbed structure can be illustrated as follows: The mass of the ball is drastically reduced compared to a solid ball. This not only reduces the material requirement during manufacture, but also the forces required to actuate the shut-off element. Depending on the given loads, the ribs and stringers can be arranged closer or further apart.
  • the shut-off element according to the invention can be injection molded be produced with little distortion and with low manufacturing tolerances, making post-processing unnecessary.
  • the low mass permits switching times, that is to say the total time of the opening and closing process of the media mass control element essentially below a time period of approximately 2.5 milliseconds (ms) and in particular essentially in a time range of approximately 0.5 ms to approx. 2.5 ms to reach.

  • the media mass control element according to this aspect of the present invention is characterized in that the shut-off element is designed as a ball flattened on one or both sides, the flattened surfaces of which are essentially parallel to the passage opening or perpendicular to the axis of rotation of the shut-off element.
  • the dimension of the media mass control element in the direction of the axis of rotation of the shut-off element can be reduced compared to that of a media mass control element with a completely spherical shut-off element.
  • the media mass control element according to the invention which is flattened on at least one side, does not show this problem.
  • the width of a double-flattened media mass control element according to the invention is hardly greater than that of a conventional throttle valve. In the flattened area e.g. Potentiometers or other control, sensor and / or regulating units can be accommodated.

In at least one position of the shut-off element, the entrance opening and the through opening and the through opening and the exit opening are respectively aligned. In at least one other position of the shut-off element, the connection between the inlet and outlet opening is at least partially closed.
  • the media mass control element according to this aspect is characterized in that the through opening of the shut-off element changes from a substantially circular cross section on the inlet side to an elongated cross section on the outlet side, the width of the through opening remaining essentially the same.
  • the through opening can essentially be described as a laterally flattened truncated cone-like cavity which has an essentially circular cross section at one end and a rather elongated cross section at the other end.
  • part of the shut-off element is recessed on the air outlet side, so that the aerodynamics on the outlet side are not disturbed by component segments which protrude into the air outlet storm stream.
  • the flow is restricted to only one side of the shut-off element in comparison with a conventional ball shut-off valve which evenly rotates the through opening at both ends of the ball against the housing and thus obstructs the flow of the medium at two points.
  • a conventional ball shut-off valve which evenly rotates the through opening at both ends of the ball against the housing and thus obstructs the flow of the medium at two points.
  • the following advantageous effect is thus achieved: in a conventional ball valve, the flow of the medium is hindered at the transition from the inlet side to the through hole of the shut-off ball and changes into a turbulent flow.
  • the second transition from the through hole to the outlet side represents the same cross-sectional constriction as the first transition, with the difference that the flow resistance is higher for a turbulent flow. This makes it difficult to control the flow behavior.
  • the flow is only impeded by a cross-sectional constriction, and the flow is less turbulent after the media mass control element, and the flow behavior can thus be better controlled.
  • a media mass control element having a housing and a shut-off element.
  • the case points thereby an entrance opening and an exit opening.
  • the shut-off element is rotatably mounted in the housing and has an essentially spherical geometry with a through opening.
  • the shut-off element has an axis of rotation defined by a passage in the housing, about which it can be rotated mechanically. In at least one position of the shut-off element, the entrance opening and the through opening and the through opening and the exit opening are respectively aligned. In at least one other position of the shut-off element, the connection between the inlet and outlet opening is at least partially closed.
  • the media mass control element is characterized by a shut-off element which essentially forms the shape of two hemispheres which are arranged offset with respect to one another and partially abut one another. In essence, the shape could be described as a sphere that was divided in the middle and reconnected with a slight offset.
  • This aspect of the present invention represents an optimized sealing concept in the closed state of the ball segment control unit.
  • the inlet side is offset in the area of a circumferential seal so that the seal can rest on the entire body over the entire surface.
  • a gap between the shut-off element and the housing in the open state essentially forms the shape of two semi-spherical shells which are arranged offset with respect to one another.
  • this construction ensures that the media mass control element forms a stop for the movement of the shut-off element in the open state.
  • the particularly desired effect is that the shut-off element narrows the gap between the shut-off element and the edge of the inlet or outlet openings when it is moved in the direction of the closed position.
  • the shut-off element preferably has an essentially tubular section which defines the through opening and which is provided with at least one rib.
  • the section and the ribs have essentially the same wall thickness.

  • Plain bearings or rolling bearings such as ball, roller or needle bearings can be considered as bearings.
  • the storage of the shut-off element brings special advantages. As a result, the ribs and the stringers no longer have to guide the shut-off element in the housing, so that the ribs can no longer get caught on the inlet or outlet opening.
  • the bearings can also reduce wear, which is particularly important for media mass controls that have short switching times.
  • the media mass control element can thus be designed with a certain gap between the housing and the shut-off element, which further reduces the forces for actuating the media mass control element.
  • the storage means that all ribs and stringers that are not necessary for reasons of stability or sealing can be dispensed with.
  • the shut-off element preferably has at least one peripheral seal which seals the inlet and / or the outlet opening when the shut-off element is closed.
  • the seal applied to the shut-off element means that even a ribbed surface cannot wear the seal excessively quickly.
  • Another advantage of the seal attached to the shut-off element is that the seal can only be attached to the ribs and stringers and to the ends of the tubular section or to the surfaces that adjoin the passage. Of course, a seal running around the bearing can also be attached to the shut-off element.

  • the seal can be located on any outer rib segment, but it can also be fixed on only a few segments, for example on the front edge and all the way back around the bearings. Ideally, the seal is closed all round.
  • the front edge closes the ball segment relatively media-tight, since this edge lies firmly on the front edge of the housing.
