Definitions

  • the invention relates to an exhaust gas recirculation valve system for internal combustion engines for exhaust gas recirculation with a drive shaft, an eccentrically driven clutch unit and at least two valves, wherein each of the valves at least a valve rod, a valve closing body and a valve seat and wherein the coupling unit is an operative connection between the drive unit and the at least two Valve rods manufactured in such a way that the rotational movement of the drive unit is converted into a linear movement of the valve rods.
  • valve system for example, in the US 4,027,636 disclosed.
  • two valves are actuated via a camshaft, one of which is an exhaust gas recirculation valve and one is arranged in the air inlet duct and thus serves as an air throttle.
  • a decoupling of two exhaust gas lines and a regulation of an exhaust gas flow in two exhaust gas lines by means of a controllable drive is not disclosed.
  • Another disadvantage is the required large space.
  • EGR valves which essentially have a drive unit, a gear unit with a pin eccentrically arranged bearing as a coupling part and a valve with valve rod, valve closing member and valve seat, wherein the gear unit is in operative connection with the valve rod and thereby open the valve or can close. Furthermore, it has an outlet opening and an inlet opening.
  • the present invention seeks to provide a valve system which avoids the disadvantages mentioned above and also simple and inexpensive to manufacture.
  • the coupling unit consists of a coupling element driven eccentrically by the drive shaft and at least two coupling strands fixedly connected to the coupling element, the coupling strands each consisting of a first eccentric, a connecting shaft arranged in a bearing, which at its first end with the first eccentric and at its second end is fixedly connected to a second eccentric and a fixedly connected to the second eccentric bearing element.
  • Such a designed valve system thus requires only a drive unit and optionally a sensor unit for actuating a plurality of valves. Furthermore, only one housing is required for the valves so that the entire valve system can be pre-assembled on the intake line or the exhaust gas lines. This considerably reduces both the mechanical and the electrical installation effort, which in addition to the reduced component costs also results in a reduction of the assembly costs.
  • valves either synchronously, ie simultaneous opening and closing of the valves, especially in internal combustion engines in V-design or asynchronous, ie temporally offset opening and closing valves, to operate. This creates a variety of installation options for such a valve system.
  • a particularly simple form of storage of the connecting shaft of the two eccentrics is created by the fact that the bearing is connected to the housing of the valve system.
  • the bearings are advantageously arranged in scenes, which are firmly connected to the valve rods, so that a positive guidance of the valve rods is formed.
  • valve system is thus created, which is simple and robust and also saves weight. Furthermore, one achieves a high degree of flexibility with regard to installation and pre-assembly. Due to the forced operation, the valves can also be actively closed and locked.
  • the illustrated valve system consists of a drive unit 1, which consists of an electric motor 2 with a planetary gear 3 and a drive shaft 5 emerging from a motor housing 4.
  • a drive unit 1 which consists of an electric motor 2 with a planetary gear 3 and a drive shaft 5 emerging from a motor housing 4.
  • an eccentrically arranged driver 6 is fixedly mounted, which in turn is rotatably connected via a pin 7 with a coupling element 8, which is perpendicular to the drive shaft 5.
  • the rotational movement of the drive shaft 5 is transmitted via this coupling element to two identical coupling strands 9.
  • 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, which in turn is connected via a pin 12 to the coupling element 8, and a in a bearing 13, which is fixedly mounted with respect to the drive shaft 5, arranged connecting shaft 14, which connects the first eccentric 11 with a second eccentric 15.
  • This second eccentric 15 is in turn connected via a pin 16 to a bearing element, in this case a rolling bearing 17.
  • the two rolling bearings 17 are each arranged in a slot 18, the movement of the coupling unit 10 and the rolling bearing 17 on two valve rods 19, which at the same time through the backdrop 18 be forced, transfers.
  • FIG. 3 the individual directions of movement of the components of the coupling unit 10 are once again shown by arrows.
  • the rotational movement of the drive shaft 5 is converted by the eccentrically arranged driver 6 substantially in a horizontal movement of the coupling element 8.
  • this horizontal movement is substantially converted via the fixed rotating connecting shaft 14 in a rotational movement of the second eccentric 15.
  • This transmits this movement to the bearings 17, resulting in a substantially vertical movement of the scenes 18 and thus the firmly connected to the scenes valve rods 19 is formed.
  • this vertical movement will be 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 plates By the movement of the drive shaft 5 in the opposite direction, the valve plates are lifted from the valve seat 21, whereby a fluidic connection between the outlet port 23 and inlet port 24 is made.
  • a spring element 25 is provided, which holds the valve rod 19 in the direction of the bearing 17 under tension.
  • This bias is created by introducing the spring element 25 between a bearing surface 26 of the housing part 22 and a support ring 27, which is either part of the link 18, or as in the exemplary embodiment is arranged under the gate 18 spring plate.
  • the support ring 27 of the link 18 is loaded in the direction of the roller bearing 17 by the force of the spring element 25 and thus the valve plate 20 is pressed via the valve stem 19 against the valve seat 21.
  • the housing part 22 is constructed so that it not only includes the valve seat 21, the outlet opening 23, the inlet opening 24 and the support surface 26 for the spring element 25, but additionally has two bearing receiving socket 28 which receive the bearings 13 of the connecting shafts 14.
  • the entire valve system is closed by a housing cover, not shown in the drawings.
  • the valves Due to the separation of the exhaust gas strands in the inlet region, the valves, depending on the position of the respective first eccentric 11 to the second eccentric 15 either synchronously, which is useful in particular in internal combustion engines in V-design, or as in FIG. 4 shown asynchronously operated.
  • the second eccentric 15 of a coupling strand 9 is rotated by 180 ° compared to the eccentric 15 of the other coupling strand, whereby an opposite movement of the two valve rods 19 is formed.
  • any angular position of the two eccentric 15 is conceivable to each other.
  • a water cooling can be integrated into the housing, which makes it possible to install this valve when used as an exhaust gas recirculation valve and suction pipes made of plastic or magnesium.
  • valves with an actuator are actuated independently by the use of the coupling unit.
  • Such a design reduces costs, space and the number of components and thus weight.
  • the valves are actively closed by the forced operation and also held in this closed position.
  • Changes in the execution for example, a multi-part of the housing or other design of the valves, for example, as a cone valve or similar. do not limit the scope of the invention.
