Definitions

  • the invention relates to a turbocharger according to the preamble of claim 1.
  • the throttle valve mounted behind the compressor of the turbocharger in the air collector.
  • the throttle closes and the compressor of the turbocharger would promote due to its inertia air against a nearly closed volume. This would mean that the compressor would no longer be able to pump continuously and backflows would form. The compressor would pump. The speed of the turbocharger would therefore decrease very quickly.
  • turbochargers can be provided with a recirculation valve (also called a recirculation valve), which opens pressure-controlled from a certain negative pressure via a spring-loaded valve element, a connecting channel, which returns the air to the compressor inlet.
  • a recirculation valve also called a recirculation valve
  • the compressor housing which has a valve flange for the recirculation valve, mainly produced by chill casting or sand casting. Furthermore, it is also known to produce such a valve housing in die casting, but here several moldings must be joined together, since the geometry of the individual moldings is to be chosen so that they can be demoulded in the die casting. However, this increases the design effort and thus the manufacturing cost.
  • Verbhdungskanal the compressor housing which leads from the compressor spiral to the compressor inlet and the flange of the valve flange for the recirculation valve at an angle of large 0 ° to the reference side of the compressor housing, it is possible to use in die casting so-called slide, the can be pulled out of the compressor housing due to the setting of said angle to values of more than 0 ° after the casting process, which makes it possible to the compressor housing of the turbocharger according to the invention cost-effective way to produce in one piece in the die-casting.
  • a compressor housing according to the invention is defined as a self-negotiable object.
  • Fig. 1 is a perspective view of a turbocharger according to the invention for explaining the basic structure thereof;
  • FIG. 2 is a sectional view of the compressor housing according to the invention for a turbocharger according to FIG. 1.
  • turbocharger 1 serves to illustrate the principal 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 conventional components such as a rotor shaft, the compressor and the turbine wheel are provided, which will not be explained in more detail below, since they are not required for the explanation of the principles of the present invention.
  • FIG. 2 the compressor housing 5 of the compressor 3 is shown in a sectional view.
  • the compressor housing 5 has a reference surface BF, which is arranged perpendicular to the turbocharger axis A L and the coil axially limited to the bearing housing side.
  • the compressor housing 5 has a valve flange 6, on which the recirculation valve explained in the introduction, which in FIG. 2 is not shown in detail, can be fastened.
  • the valve flange 6 has a flange surface 8, in which an inlet opening 10 is arranged, to which a connecting channel 9 connects to the compressor inlet 7.
  • the valve flange 6 has a valve seat 11 for the closing element, not shown, of the recirculation valve.
  • the channel axis A K is arranged at an angle ⁇ to the valve seat.
  • the flange 8 is arranged at an angle ⁇ to the reference surface BF, which, as the angle ß in the illustrated embodiment is greater than 0 ° and preferably formed as an acute angle.
  • the line BF 1 represents a parallel displacement of the reference surface BF in order to be able to represent the position of the angle ⁇ in a simplified manner.
  • valve housing 5 By choosing the angle ⁇ and ß with angular dimensions of more than 0 °, it is possible to produce the valve housing 5 in one piece by die casting, as it is possible by an appropriate choice of the angle ⁇ and ß greater than 0 °, in the range of to be cast compressor housing in which the connecting channel 9 is to arise to arrange a slide, which can be removed from the molded valve housing 5 after the casting process.
  • A inner diameter of the valve opening 10
  • a L ; G distance of the center of the valve opening 10 to the
  • Turbocharger axis A L I distance between the reference side or the reference surface BF and the center of the valve opening 10; V: distance of the intersection of the valve flange axis A VF with the spiral cross-section center to the reference surface BF; R: distance of the inner wall of the inlet nozzle 7 of the

Abstract

L'invention concerne un turbocompresseur (1), comprenant : une turbine (2) ; et un compresseur (3) relié à la turbine (2) via un corps de palier (4) et comportant un carter de compresseur (5) qui présente une surface de référence (BF) perpendiculairement à un axe (A<SUB>L</SUB>) du turbocompresseur, une bride de soupape (6), pourvue d'un siège de soupape (11), pour une soupape à air ambiant pulsé, et un canal de liaison (9) vers une entrée de compresseur (7). La bride de soupape (6) présente une surface de bride (8) qui est disposée inclinée sous un angle calculable (a) par rapport à la surface de référence (BF), et le canal de liaison (9) présente un axe de canal (A<SUB>?</SUB>) qui est disposé incliné sous un angle calculable (ß).
