Definitions

  • the invention relates to a turbocharger according to the preamble of claim 1.
  • the throttle valve which is used to specify the engine load, is located behind the compressor of the turbocharger in the air collector.
  • the throttle valve closes and the turbocharger's compressor would deliver air against an almost closed volume due to its inertia. The consequence of this would be that the compressor could no longer deliver continuously and backflows would form.
  • the compressor would pump. The speed of the turbocharger would therefore decrease very quickly.
  • turbochargers can be equipped with a recirculation valve (also called a diverter valve), which opens pressure-controlled from a certain negative pressure via a spring-loaded valve element, a connection channel that returns the air to the compressor inlet. So it’s
  • a turbocharger corresponding to the preamble of claim 1 is known from DE 100 20041 C2.
  • the valve closing part is designed as a membrane with a circumferential sealing lip. Pressure and temperature loads acting on this diaphragm, as well as the presence of aggressive motor blowby, lead to premature wear and premature failure of the diaphragm and thus of the diverter valve.
  • the embodiment of the present invention no longer contains a membrane as a valve closing part.
  • This is completely replaced either by a shut-off device that has a sealing ring with an annular body, such as an O-ring body, or by a shut-off device that has an annular body with a sealing lip that seals on a conically tapering surface of the valve head carry out.
  • This combination of an axial and radial seal compensates for tolerances in manufacturing depth and increases the reliability and safety of the seal.
  • the tapered sealing system ensures maximum tightness in the extended state ("closed" position) and the In the open state (“open” position), minimal friction can be reached.
  • the system pressure P2 increases . By pressing the sealing lip of the diverter valve, the sealing capacity is compensated for and thus also compensates for possible abrasion losses.
  • a diverter valve according to the invention is defined as an independently tradable object.
  • FIG. 1 is a perspective view of a turbocharger according to the invention to explain its basic structure.
  • FIG. 2 shows a schematically, slightly simplified sectional illustration of the air recirculation valve for a turbocharger according to FIG. 1.
  • turbocharger 1 serves to illustrate the basic components of a turbocharger 1 according to the invention, which, as usual, has a turbine 2 and a compressor 3, which is connected to the turbine 2 via a bearing housing 4.
  • a turbine 2 and a compressor 3 which is connected to the turbine 2 via a bearing housing 4.
  • all other usual components such as a rotor shaft, the compressor wheel and the turbine wheel are also provided, but these are not explained in more detail below, since they are not necessary for explaining the principles of the present invention.
  • Fig. 2 the overflow air valve 5 of the compressor 3 according to the invention is shown in a sectional view.
  • the shut-off device 12 shown therein has an annular body 15 on which an annular sealing lip 14 is arranged pointing radially inwards. According to the representation chosen in Fig. 2 the sealing lip 14 is arranged at an acute angle with respect to the ring body 15 facing upwards.
  • the sealing lip 14 is part of a sealing device 11 which also has a valve sealing head 16 which has a cone section 18 which tapers from a cylinder section 17 in the direction of the compressor housing 5 of the compressor 3.
  • the cylinder section 16 is followed by the cone section 18, which extends from one of its ends 20 with a diameter that corresponds to that of the cylinder section 17 to an end 20 ′ with a smaller diameter in the direction of the compressor housing 5 rejuvenated.
  • the valve sealing head 16 also has a stop plate 19 which adjoins the end 20 'of the cone section 18 via a central cylindrical connection region 34.
  • the diverter valve 10 also has a housing part 21 in which a receiving groove 23 is arranged, into which the annular body 15 of the shut-off element 12 is inserted, as can be seen in detail from FIG. 2.
  • the housing part 21 also has an underside 24 which faces the stop plate 19. At least one stop part 22 is arranged on the underside 24, which can be seen in FIG. 2. This stop part 22 limits the stroke of the valve sealing head 16 and thus prevents the coil 25 from striking the iron core 32.
  • the stop part 22 is preferably ring-shaped, but can also consist of several separate individual parts.
  • the diverter valve 10 also has an armature 25 which is arranged in a coil 26. The coil 26 surrounds the armature 25 on the circumference.
  • the power supply to the coil 26 is ensured by an electrical connector 35.
  • the stop plate 19 is provided with at least one pressure compensation bore 27 which connects an interior 28 of the compressor housing 5 with a cavity 29 which is delimited by the cylinder section 17 and the cone section 18.
  • the armature 25 of the diverter air valve is also provided with at least one pressure compensation bore 30, which connects the cavity 29 to a receiving space 31 in the diverter air valve 10.
  • the receiving space 31 is delimited by the coil 26, the armature 25 and an iron core 32 opposite this at the upper end of the air recirculation valve 10.
  • a coil spring 33 is arranged, which is supported on its upper end on the iron core 32 and on the other lower end on the armature 25 according to the illustration selected in FIG. 2.
