Definitions
- Liquid container with shut-off device Liquid container with shut-off device.
- Fluid reservoirs for hydraulic units are known in many forms, for example as brake fluid reservoirs for supplying brake devices for hydraulic motor vehicle brake systems.
- the hydraulic connection to the respective unit is usually made by connecting pieces that are integratively formed on the outside of the container housing and that are sealingly received in corresponding receiving seats in the hydraulic unit.
- shut-off devices are known which have to be mounted in the interior of the container housing during the manufacture of the liquid container.
- shut-off device Complexity in manufacture, construction and assembly, a large space requirement for assembly tools and tool inserts and the need for additional structural elements for storing and fixing the shut-off device within the container housing are viewed as disadvantageous lig in such solutions.
- large-volume components must be handled, which also have to be completely scrapped in the event of a fault.
- Another shut-off device is known from DE 102014 213 709 A1, which is implemented in the form of a cartridge that can be inserted from the outside into the connection stub of a finished container.
- Such a solution additionally limits the diameter of the inner channel in the connection piece and reduces the flow cross-section, and can therefore preferably be used for larger diameters.
- Generic liquid containers are usually constructed as a shell steering body from two half-shells welded to one another in a pressure-tight manner.
- the two half-shells are usually manufactured in an injection molding process.
- the aim is to adapt all sprue parts to the demolding direction, for example to design nozzles directed in the demolding direction. Even minor adjustments to different installation positions and installation space conditions at the installation site can lead to completely redesigned container housings and injection molding tools.
- shut-off devices which could be adapted more flexibly to different installation configurations, the shut-off devices could also be used with comparatively narrow connecting pieces and their assembly and functional testing could be carried out more easily.
- Fig.l shows a greatly simplified representation of an embodiment of the liquid container within a braking device for a hydraulic motor vehicle brake system in cross section.
- FIG. 2 three-dimensional representation of a further embodiment of the liquid container.
- Fig. 3 the module according to the embodiment according to Fig.l in assembly (a) and exploded view (b).
- FIG. 4 shows an enlarged sectional view of an embodiment of the connecting piece with the shut-off device mounted.
- FIG. 5 three-dimensional views of a base body of the module according to FIG. 3
- FIG. 1 shows, in a greatly simplified manner, a braking device 100 for a hydraulic motor vehicle brake system, with a hydraulic unit 2 for generating and / or modulating a brake pressure and a fluid container 1 mounted on unit 2.
- the liquid container 1 has a container housing 3, the interior of which in the embodiment shown is divided into two inner chambers 4, 4 'which can be filled with a brake fluid.
- a filler neck 17 that can be closed with a closure cap is provided.
- the hydraulic connection between the unit 2 and the inner chambers 4, 4 takes place through inner channels 6, 6 'within two connecting pieces 5, 5' arranged parallel to one another and arranged on the outside of the liquid container 1.
- the two connecting pieces 5, 5 ' are received in corresponding receiving seats 7, 7' in the unit 2 and are sealed to the outside therein by means of sealing elements 19, 19 '.
- shut-off devices 8, 8 ' are used to forcibly block the inner channels 5, 5' when the connecting pieces 5, 5 'are located outside of the receiving seats 6, 6'.
- FIG. 4 Reference is made to FIG. 4 for the preferred construction of a shut-off device 8.
- the liquid container 1 is constructed as a shell body with egg ner lower and an upper half-shells 20, 20 '.
- the two half-shells 20, 20 ' are manufactured in an injection molding process and then welded to a circumferential joint seam 21 in a hydraulically tight and pressure-resistant manner.
- the joining seam 21 runs in a so-called dividing plane 22, which is favorable for manufacture.
- the dividing plane 22 is preferably oriented orthogonally to the axis of the filler neck 17 which is designed as an integral part of the upper half-shell 20 '.
- the two connecting pieces 5, 5 ' are oriented orthogonally to the filler neck 17 or parallel to the dividing plane 22 and thus transversely to the direction of deformation of the lower half-shell 20.
- connecting pieces 5, 5 'formed in one piece with the half-shell 20 such a configuration would not be realizable without a comparatively complex injection molding tool with separate tool inserts.
- the container housing 3 has an opening 10 in an outer wall which is easy to manufacture and which is closed from the outside by the module 9 so that it is pressure-tight.
- connection between the module 9 and the container housing 3 is stoffschlüs sig, in particular realized by welding, in a particularly simple and permanently tight manner.
- Other types of connection such as gluing, screwing, locking, clipping, etc. are also if of course permitted within the invention
- the module 9 can be built, function-checked, stored and transported as a separately manageable assembly without the voluminous container housing 3 having to be handled at the same time.
- the alignment of the two connecting pieces 5, 5 is, in contrast to the embodiment described above, slightly inclined relative to the orthogonal of the axis of the filler neck 17 or relative to the separation level 22.
- the connecting pieces 5, 5 are essentially transverse to the axis of the filler neck 17, however aligned exactly orthogonally to it. This may be necessary, for example, to adapt the plug-in direction to the slight inclination of the spray wall in the vehicle on which the unit 2 is installed on it.
- the module 9 according to the invention can effectively be used as a pre-equipped and functionally tested unit component which is attached to the container housing 3 on differently designed and shaped variants.
- the respective variants of the container housing 3 or individual Half-shells 20, 21 can be produced in simply structured injection molding tools and can thus be adapted to different installation conditions at a comparatively low cost - for example, different orientations of the connection pieces 5, 5 ', external shapes, internal structures, volumes and the like.
- the liquid container 1 could be efficiently adapted to different hydraulic units 2 with, for example, differently designed interfaces or liquid throughputs by a suitable variant of the module 9 being attached to the same container housing 3.
- FIG. 3 shows the exemplary embodiment of the module 9 according to FIG. 2 in an assembled and exploded view.
- the module 9 has a base body made of plastic by injection molding, the two connecting pieces 5, 5 'are formed in one piece with the base body 15.
- the shut-off device 8 is arranged essentially completely within the connecting piece 5.
- a spring 12 and a pin-shaped valve body 11 is pushed from the outside into the connector 5 so that the inner-chamber end of the Ventilkör pers 11 protrudes from the connector 5 inward.
- a sealing body 13 is attached, which at the same time serves to hold the valve body 11 in the connection stub 5 in the closed state.
- shut-off device 8 in the closed state in cross section.
- the shut-off device 8 is arranged in a substantially space-saving manner in the inner channel 6 of the connecting piece 5 and is fastened. It has a spring-loaded valve body 11 with a sealing body 13 provided on the inner chamber side. In a closed state shown here, the sealing body rests on a valve seat 14 formed in the mouth area of the inner channel 6 and thereby blocks the inner channel 6.
- the length of the valve body 11 is designed in the embodiment shown in such a way that it protrudes outwards from the connection piece 5 in the closed state.
- valve body 11 can also be shortened so that it is located completely within the inner channel 6 in the closed state.
- a separate support means is required within the receiving seat zes 7, which engages axially in the channel 6 when the socket is set in the receiving seat 7 and moves the valve body 11 in the direction of the inner chamber 4.
- FIG. 5 shows the base body 15 of the module 9 according to FIGS. 2 and 3.
- the module 9 is an optimal place for placing separate fastening means 18, which are provided for fixing the liquid container 1 on the unit 2 are. Adaptations to different fixing interfaces can thus be implemented comparatively inexpensively, without the container housing 3 having to be changed for this purpose.
- the fastening means 18 is implemented as a pair of eyelets formed in one piece with the base body 15, which are provided for inserting a transverse pin (not shown here).
- a transverse pin (not shown here).
- one of the eyelets has special Federla rule, which are used to hold a thickened end of the cross pin.
- connection surface 16 is provided on the base body 15.
- the connection surface 16 can be adapted accordingly as required.
- this area of the base body can be designed with an increased material thickness and an adapted, for example roughened, surface.
- the remaining areas of the base body 15, on the other hand, can be optimized, for example, for inexpensive production and low material consumption.
