Definitions

  • the invention relates in particular to a valve system for internal combustion engines for exhaust gas recirculation with at least one housing in which a drive unit with a drive shaft, an eccentrically driven clutch unit and at least a valve is arranged, the valve comprising at least one valve rod, a valve closing body and a valve seat, the coupling unit the rotational movement of the drive unit in a linear movement of the valve rods transforms.
  • Such a valve system has in essentially a drive unit, a gear unit with a pin eccentrically arranged bearings as coupling parts and a valve with valve rod, Valve closing member and valve seat, the gear unit with the valve rod in There is an active connection and can thus open or close the valve. Furthermore it has an outlet opening and an inlet opening.
  • the object of the invention is to create a valve system create, which avoids the disadvantages mentioned above and is also easy to set up and is inexpensive to manufacture.
  • the coupling unit advantageously consists of a through the drive shaft eccentrically driven coupling element and at least two fixed to the coupling element connected coupling strands, the coupling strands each from a first eccentric, a connecting shaft arranged in a bearing, that at its first end with the first eccentric and at its second end with a second eccentric is firmly connected and one is fixed to the second eccentric connected bearing element exist.
  • a valve system designed in this way therefore requires several valves to be actuated only one drive unit and possibly a sensor unit. Furthermore only one housing is required for the valves, so that the entire valve system pre-assembled on the intake line or the exhaust lines can. This reduces both the mechanical and the electrical assembly effort considerably, which in addition to the reduced component costs also a There is a reduction in assembly costs.
  • valves depending on the angular position of the first to the second eccentric of a clutch train either synchronously, that is simultaneous opening and closing of the valves, especially in internal combustion engines V-shaped or asynchronous, i.e. opening and closing at different times of the valves to operate. This creates a variety of installation options for a created such a valve system.
  • a particularly simple form of mounting the connecting shaft of the two eccentrics is created in that the bearing with the housing of the valve system connected is.
  • the roller bearings are advantageously arranged in scenes that with the valve rods are firmly connected, so that positive guidance of the valve rods arises.
  • valve system When this valve system is attached to suction pipes made of plastic or magnesium water cooling can be integrated into the housing.
  • valve system is created which is simple and is built robustly and also saves weight. Furthermore one reaches one high flexibility with regard to installation and pre-assembly. Due to the forced control the valves can also be actively closed and locked.
  • Figure 1 shows a perspective view of a valve system according to the invention with cut housing and without housing cover.
  • Figure 2 shows a perspective view of the valve system without a drive unit and without housing cover with cut housing.
  • Figure 3 shows a perspective view of a section of the valve system without Housing cover and here in particular a coupling unit according to the invention and a backdrop for forced guidance, with arrows to show the direction of movement of the individual components of the coupling device.
  • Figure 4 shows a perspective view of an output part of the clutch unit asynchronous operation.
  • the valve system shown consists of a drive unit 1, which one Electric motor 2 with a planetary gear 3 and one from a motor housing 4 emerging drive shaft 5 there.
  • a drive unit 1 On the end of the from the engine case 4 emerging drive shaft 5 is an eccentrically arranged driver 6 firmly attached, which in turn via a pin 7 with a coupling element 8, which is perpendicular to the drive shaft 5, is rotatably connected.
  • the rotary motion the drive shaft 5 is on this coupling element on two identical coupling strands 9 transferred.
  • the eccentrically arranged driver 6, the pin 7, the Coupling element 8 and the two coupling strands 9 form a coupling unit 10.
  • Each of the two coupling strands 9 consists of a first eccentric 11, the is in turn connected to the coupling element 8 via a pin 12, as well as one in a bearing 13 which is fixedly mounted with respect to the drive shaft 5 Connecting shaft 14, the first eccentric 11 with a second eccentric 15 connects.
  • This second eccentric 15 is in turn connected to a pin 16 a bearing element, in this case a roller bearing 17.
  • This roller bearing 17 simultaneously forms the end member of the coupling unit 10 or the two Coupling strands 9.
  • the two roller bearings 17 are each arranged in a link 18, the movement of the coupling unit 10 or the rolling bearing 17 on two Valve rods 19, which are simultaneously positively guided by the backdrop 18, transmits.
  • FIG. 3 shows the individual directions of movement of the components of the coupling unit 10 represented again by arrows.
  • the rotary motion the drive shaft 5 by the eccentrically arranged driver 6 in essentially converted into a horizontal movement of the coupling element 8.
  • This transmits this movement to the roller bearing 17, from which a essential vertical movement of the scenes 18 and thus the fixed with the scenes connected valve rods 19 arises.
  • two valve plates 20 which are fixedly connected to the valve rods 19 against their Valve seats 21, which are part of a housing part 22, pressed.
  • valve plate 20 By moving the Drive shaft 5 in the opposite direction, the valve plate from the valve seat 21 lifted off, whereby a fluidic connection between the outlet opening 23 and Inlet opening 24 is made.
  • a spring element 25 is provided, which the valve rod 19 in the direction of Bearing 17 holds under bias. This pre-tension arises through the introduction of the spring element 25 between a support surface 26 of the housing part 22 and a support ring 27, which is either part of the backdrop 18, or as in the embodiment is a spring plate arranged under the backdrop 18.
  • the support ring 27 of the backdrop 18 In the event of a failure of the electric motor 2 is the support ring 27 of the backdrop 18 in the direction of Rolling bearing 17 loaded by the force of the spring element 25 and thus the valve plate 20 pressed against the valve seat 21 via the valve rod 19.
  • the housing part 22 is constructed so that it is not only the valve seat 21, the outlet opening 23, the inlet opening 24 and the bearing surface 26 for the spring element 25 includes, but also has two bearing receiving base 28, which Bearing 13 of the connecting shafts 14.
  • the entire valve system is closed by a housing cover, not shown in the drawings.
  • the valves can vary depending on Position of the first eccentric 11 in relation to the second eccentric 15 either synchronously, which is particularly useful for V-shaped internal combustion engines, or as shown in Figure 4 are operated asynchronously.
  • the second eccentric 15 one coupling strand 9 by 180 ° compared to the eccentric 15 of the other Coupling strand rotated, causing an opposite movement of the two Valve rods 19 are formed.
  • every angular position is the two eccentrics 15 conceivable to each other.
  • a water cooling can advantageously be integrated into the housing, which makes it possible to use this valve on intake manifolds when used as an exhaust gas recirculation valve made of plastic or magnesium.
