In addition, the housing has a fixing device, which allows the butterfly-valve unit (11) to be located on an intake module (1) in such a way that the connecting sleeve (17) is inserted into a lateral recess (8) of the intake module (1) in the vicinity of a butterfly valve pipe section (6).

Description

Throttle valve device
The present invention relates to have the throttle valve device of housing, this housing has sleeve pipe, axle is installed in this sleeve pipe and attaches troops to a unit in this closure.This throttle valve device is particularly suitable for being installed in the internal-combustion engine.
Disclose a kind of closure sleeve pipe in DE19825727A1, this sleeve pipe is used for power of IC engine is regulated and is arranged between the outlet of air cleaner for internal combustion engine and the inlet that air inlet is module.The closure sleeve pipe has housing, and this housing has sleeve pipe, axle is installed in sleeve pipe and attaches troops to a unit in this closure.The closure sleeve pipe is fixed on the outlet side of air-strainer and approaching side that air inlet the is module inlet by fixing device.
The objective of the invention is so to improve this known throttle valve device, so that it more simply and economically is used to different purposes.
The object of the invention realizes by the feature of independent claims.The feature of advantageous forms of implementation of the present invention has provided in the dependent claims.
The characteristics of the theme of dependent claims are: throttle valve device has fixing device, by this fixing device, it is in the module that throttle valve device can be arranged in air inlet, so that the sleeve pipe of throttle valve device housing radially being installed in the side space that air inlet is a module along it in the zone of closure pipeline section.
This side space is arranged in the zone of closure pipeline section.It radially and axially forms, and pipeline section or the housing that surrounds this pipeline section do not interrupt fully, have therefore formed its end.So throttle valve device allows to adopt identical fixing device in simple mode for the different application occasion that for example has different closure pipeline section diameters and casing diameter.Therefore, closure can only be required to be at internal-combustion engine and make the application in the model of manufacturer and the detection taken a lot of trouble, and can omit for the application in other model.
In addition, can be arranged in air inlet easily be in the module to throttle valve device.In addition, especially make needed material be less than common closure sleeve pipe basically by the sleeve pipe cross section that increases, common closure sleeve pipe is connected on the inlet side end that air inlet is a module with flange usually.Housing is made by composite according to an advantageous embodiment, and this is particularly advantageous, because because the quality of needed composite is less, thereby accurately processes simple.
According to schematic figures embodiments of the invention are described in further detail.Wherein:
Fig. 1 is that throttle valve device and air inlet are module;
Fig. 2 is among second embodiment, the throttle valve device of Fig. 1;
It is throttle valve device in the module, Fig. 1 that Fig. 3 is to use the air inlet at Fig. 1.
The 26S Proteasome Structure and Function components identical is represented with identical mark in institute's drawings attached.
Air inlet is that module 1 (Fig. 1) has trap 2 and suction tude 3 to 5, and these suction tude 3 to 5 are led in the intake duct of the internal-combustion engine that does not illustrate.Air inlet is that module 1 also has closure pipeline section 6, and this closure pipeline section 6 directly or indirectly links to each other with air-strainer at its side that enters.Closure pipeline section 6 has a space, and the housing that this space can not make pipeline section along form radial and axially or surround this pipeline section interrupts fully.In addition, be provided with one and survey flange 9 near space 8, this side flange 9 is used for fixing throttle valve device.
Throttle valve device 11 has housing, and this housing has cover 13 and lower housing portion 15.Preferably, lower housing portion has sleeve pipe 17, and this supporting element is installed with an axle 19 and one and attaches troops to a unit in this closure 21.This sleeve pipe has only 1cm to 5cm wide vertically.Therefore, correspondingly saved quality, for as far as possible accurately being made by composite, this is very important advantage especially.
In addition, Bearing Installation part 23 is arranged in the sidepiece of closure 21, and this sidepiece avoids covering 13, and this cover 13 forms taper, preferably becomes circular cone shape.Therefore, on the one hand, the axle that closure 21 is fixed thereon obtains suitable arrangement, and on the other hand, it is in the module that the profile by the Bearing Installation part reliably and accurately is fixed on air inlet to throttle valve device 11.
Housing also has the assembling set 25 of the actuator of closure 21, and preferably, this actuator forms the electric notor with corresponding speed changer.In addition, preferably, lower housing portion 15 has plug 27, and this plug forms and is used for holding corresponding corresponding plug, so this connection is used to have the servo-drive 25 of central unit or the power supply or the electrical signal cable of a sensor that does not illustrate.In addition, be provided with a fixing device, this fixing device becomes the form of the side flange 29 of throttle valve device.In addition, groove 33 is arranged to and closure pipeline section coaxial line, therefore and with the free pipe cross section coaxial line of sleeve pipe 17, this groove 33 is installed O shapes ring 35.
The flange 9 that throttle valve device is module 1 by the flange 29 and the air inlet of throttle valve device, preferably to be fixed to air inlet by screw 37,39 be in the module.Being installed to air inlet is under the situation in the module, and sleeve pipe 17 radially is installed in the side space 8 that air inlet is a module along it in the zone of closure pipeline section 6.Therefore, it is in the module that closure is inserted into air inlet as simple inserting member, and consequently, it is particularly suitable for highly integrated module scheme.Therefore, can make that the air inlet that comprises closure is that module forms whole outside compactness, in frequent small construction space, this is favourable especially.
If fixed block becomes flange 9 forms, can especially simply and reliably to be fixed on air inlet be in the module to closure so.
By the O shape in the groove 33 that is installed to sleeve pipe 17 ring 35, can guarantee in air inlet to be that module 1 can not produce leakage flow when carrying out work in closure pipeline section 6.In addition, O shape ring is the standard piece of cheap and simple.
In addition, have the profile of taper, especially circular cone shape by making Bearing Installation part 23, can especially reliably and accurately be fixed to air inlet to throttle valve device 11 is in the module 1, can guarantee that the axle 19 of closure 21 is well settled simultaneously.Preferably, the housing of throttle valve device 11 is formed by composite.
On the one hand, its manufacture cost is lower, on the other hand, compare with the structure that forms by metal, weight saving.By making the compact structure of sleeve pipe 17, can guarantee that also closure has perfect function in internal-combustion engine carries out the whole temperature range of work.Fig. 2 shows throttle valve device, and this throttle valve device only is different sealing gaskets with the difference of Fig. 1.In this embodiment, groove 31 is equipped with sealing gasket along the profile setting of sleeve pipe 17 in this groove.
Fig. 3 shows that to be in equipment air inlet under the installation situation, that have throttle valve device shown in Figure 1 be module 1, and wherein, closure pipeline section 6 cuts along hacures, so that observe better.
