As particularly advantageous embodiment, lubricant pipe is opened to pump chamber, so that lubricant can transport pump chambers.Cause
This, ensures the lubrication of running surface in a simple manner.Here, being if lubricant pipe is opened towards lubricant pipe
It is advantageous.
Detailed description of the invention
Below with reference to the accompanying drawings the exemplary embodiment that the present invention will be described in detail, in which:
Fig. 1 shows the longitudinal sectional view of motor vehicle vacuum pump of the present invention
Fig. 2 shows combined labyrinth and carbon gland/filter element enlarged drawings of motor vehicle vacuum pump in Fig. 1
Specific embodiment
Vacuum pump component is schematically shown in Fig. 1, mainly by motor vehicles vacuum pump 2, internal combustion engine 4 and with
The lubricant pump 6 that internal combustion engine 4 is connected forms.Here, vacuum pump 2 is rotatably mechanical coupling to by plug-in type coupling assembly 8
On the crankshaft or drive shaft of internal combustion engine 4.However, it is also possible to be configured to electric vacuum pump.This electric vacuum pump can also be with
It is directly connected to drive shaft, centre is not necessarily to coupling assembly.For example, the various subsidiary components that vacuum pump 2 is used for as motor vehicles, example
As air-operated brake servo unit provides actuating vacuum.Lubricant pump 6 conveys fluid lubricant, and the lubricant for internal combustion engine 4 is supplied
It is supplied with the lubricant of vacuum pump 2.
Vacuum pump 2 is so-called vane type oil pump, including pump case 10, and pump case 10 is mainly by housing body 12 and case lid
14 compositions.Pump rotor 16 is disposed in pump case 10, pump rotor 16 can rotate around a longitudinal axis and have the pump of removable installation
Rotor blade 18.In order to form the vacuum used for consumer, the both ends of eccentrically mounted pump rotor guide vane 18 are guided to wear
The running surface 20 of housing body 12 is crossed, so that being compressed in pump chambers 23 by the air that air intake branch 22 sucks, and is led to
Going out gas branch pipe discharge not shown in the figure is crossed, pump chambers 23 are surrounded by pump case 10 and are divided into two parts by pump rotor 16.
Pump rotor 16 has pump rotor outer surface 24, is formed together sliding with the hollow cylindrical surface 26 of pump case 10
Bearing assembly 28.In order to ensure slide bearing assembly 28 and the lubricant of the running surface 20 of housing body 12 are supplied, setting with
The lubricant provisioning component 30 that lubricant pump 6 is in fluid communication.
Pump case 10 includes the ledge surface 32 being arranged on internal combustion engine suitable position.In order to connect with unshowned drive shaft
It connects, the coupling element 34 of coupling assembly 8 is set, is rotatably fixed couples with pump rotor 16 in a known manner.
In order to ensure equally bearing lubricant provisioning component tight seal and dust-proof, lubricant entry compared with high dynamic pressure
Opening 36 is arranged in flange surface 32, in the openings press-fit combined labyrinth and carbon gland/filter element 38.Especially such as Fig. 2 institute
Show, in the present example embodiment, combined labyrinth and carbon gland/filter element 38 is made of filtration members 40, in the present embodiment filtration members
40 mainly include for limiting (clicked-on) filtering table 44 on the filtering nozzle 41 of flow, fringeware 42 and card.Annular
Sealing element 45 is placed in edge member 42.Alternatively, combined labyrinth and carbon gland/filter element 38 can be single piece.One-piece construction
Typically refer to the fringeware 42 of filtration members 40 and the one-piece construction of sealing element 45, wherein 45 injection molding of sealing element to filtering
On part 40.However, filtering table 44 can also be integrated by molding.
In this way, lubricant is by lubricant pump 6 through having the entrance opening 36 of combined labyrinth and carbon gland/filter element 38 to be pumped into neighbour
