Überdies ist die Gerätegröße des Hydraulikaggrega­ tes aufgrund des erläuterten Aufbaus nicht mehr zu verklei­ nern, was die Wahl der Einbaulage bzw. des Einbauortes er­ schwert.In German patent application P 41 07 625.7 is already a hydraulic unit for slip-controlled motor driving Stuff braking systems described, the valve body directly at one the memory, pressure generator and to central housing having drive elements is flanged. The functional elements described above are ver on all sides divides arranged in receiving bores of the central housing, so that to produce the complicated central housing and of the separately manufactured valve holder body in processing a variety of work positions to be taken into account in the sequence program of the machine tool gen. In addition, the unit size of the hydraulic unit Due to the structure explained, it can no longer be downsized nern what the choice of installation position or location sword.

Daher ist es die Aufgabe der Erfindung, ein möglichst kom­ paktbauendes Hydraulikaggregat zu schaffen, das sich auf möglichst einfache Weise präzise und kostengünstig herstel­ len läßt.It is therefore the object of the invention to achieve the most possible to create a compact hydraulic unit that is based on as simple as possible precise and inexpensive to manufacture len leaves.

Diese Aufgabe wird erfindungsgemäß durch die den Patentan­ spruch 1 kennzeichnenden Merkmale gelöst, wonach der Ventil­ aufnahmekörper die Speicher-, Ventil-, Druckerzeuger- und Antriebselemente derart aufnimmt, daß die Druckerzeugerele­ mente und das Antriebselement zwischen den im Abstand zuein­ ander ausgerichteten beiden Ventilreihen angeordnet werden können, wobei das seitlich zu den Ventilreihen überstehende Gehäusematerial des Ventilaufnahmekörpers zur Aufnahme der Speicherelemente genutzt werden kann.This object is achieved by the patent Proof 1 characteristic resolved, after which the valve  receiving body the memory, valve, pressure generator and Drive elements receives such that the Druckzeugerele elements and the drive element between them at a distance be arranged at the two aligned valve rows can, the projecting laterally to the valve rows Housing material of the valve body for receiving the Storage elements can be used.

Fig. 6 eine weitere Ausführungsform zur Dämpfungskammer. Fig. 6 shows another embodiment of the damping chamber.

Die Fig. 1 skizziert die grundlegende Anordnung der Ventil 1, 1′-, Druckerzeuger 5- und Antriebselemente 6 im Ventil­ aufnahmekörper 3. Sowohl die Aufnahmebohrung 8, welche die aus Elektromotor und Exzenterantrieb gebildeten Antriebsele­ mente 6 aufnimmt, wie auch die Ventilelemente 1, 1′ sind achsparallel ausgerichtet. Hierzu erstreckt sich die Aufnah­ mebohrung 7 des als doppelflutige Radialkolbenpumpe ausge­ führten Druckzeugerelementes 5 quer zur Achse des Elektromo­ tors und zu den Ventilachsen. In der nachfolgend gezeigten Schnittdarstellung des Ventilaufnahmekörpers 3 befindet sich somit das Druckerzeugerelement 5 zwischen den Anschlußebenen der Ventilelemente 1, 1′ und des Elektromotors. Fig. 1 outlines the basic arrangement of the valve 1 , 1 '-, pressure generator 5 - and drive elements 6 in the valve receiving body 3rd Both the receiving bore 8 , which receives the drive elements formed from the electric motor and eccentric drive elements 6 , as well as the valve elements 1 , 1 'are aligned axially parallel. For this purpose, the Aufnah mebohrung 7 extends out as a double-flow radial piston pump pressure generator element 5 transversely to the axis of the electromotive and to the valve axes. In the sectional view of the valve receiving body 3 shown below, the pressure generator element 5 is thus between the connection levels of the valve elements 1 , 1 'and the electric motor.

Fig. 2 zeigt einen Querschnitt durch den Ventilaufnahmekör­ per 3 an der Stelle A-A gemäß Fig. 1. Der Ventilaufnahme­ körper 3 weist eine im wesentlichen quadratische Blockform auf, in die zwei parallel zueinander liegende Reihen von Ventilaufnahmebohrungen 2, 2′ eingebracht sind. Zwischen den beiden Ventilreihen x, y befindet sich die hierzu achspa­ rallel verlaufende Aufnahmebohrung 7 des Druckerzeugerele­ mentes 5. Außerhalb zu den beiden Ventilreihen x, y gelegen, befindet sich die lotrecht zu den Ventilaufnahmebohrungen 2, 2′ angeordneten Aufnahmebohrungen 9, 10 für die als Be­ standteil der Speicherelemente wirksamen Druckspeicherkolben 12, 12′. Die Druckmittelbohrungen 4, 13 verbinden die Ventil­ aufnahmebohrungen 2 der in der Grundstellung als Auslaßven­ tile wirksamen elektromagnetisch geschlossenen Ventilelemen­ te 1, 1′ mit den Aufnahmebohrungen 9, 10 der Speicherelemente. Eine neben den Aufnahmebohrungen 9, 10 der Speicherelemente und dazu parallel angeordnete weitere Aufnahmebohrung 11 steht über eine Druckmittelbohrung 15 mit dem druckseitigen Pumpenabschnitt der Aufnahmebohrung 7 in Verbindung. Hydrau­ lische Druckspitzen des Druckerzeugeelementes gelangen somit zur Dämpfung der Pumpengeräusche in die zugeordnete Aufnah­ mebohrung 11. Die Aufnahmebohrung 11 ist entweder über einen separaten Deckel oder mitunter durch den als Tiefziehteil kappenförmig ausgebildeten Deckel 21 der Aufnahmebohrungen 9, 10 integriert. In der gezeigten Ausführungsform eignet sich der als Schraubverschlußstopfen ausgebildete separate Deckel 21 gleichzeitig zur Einspannung und Anpressung des die beiden Aufnahmebohrungen 9, 10 verschließenden Deckels 21, so daß Befestigungsmittel für den Deckel 21 eingespart werden können. Die den Speicherelementen zugewandte Ventil­ reihe x nimmt ausschließlich die in der Grundstellung elek­ tromagnetisch geschlossenen Ventilelemente (Auslaßventile) auf. Die zweite Ventilreihe y faßt die in der Grundstellung elektromagnetisch geöffneten Ventilelemente (Einlaßventile) zusammen. Hierdurch ergibt sich die abbildungsgemäße Kanal­ führung, wonach die Druckmittelbohrungen 4 den Druckmittel­ verbraucher 19 jeweils mit den Ventilaufnahmebohrungen 2, 2′ der Einlaß- und Auslaßventile verbinden. Durch die gezeigte Verbohrung des Ventilaufnahmekörpers 3 ist u. a. auch vorge­ sehen, die Kabeldurchführung 26 für den Elektromotor unmit­ telbar im Ventilaufnahmekörper 3 anzuordnen. Fig. 2 shows a cross section through the Ventilaufnahmekör by 3 at point AA according to Fig. 1. The valve receiving body 3 has an essentially square block shape, in which two rows of valve receiving bores 2 , 2 'lying parallel to each other are introduced. Between the two rows of valves x, y there is the receiving bore 7 of the Druckzeugerele element 5 that runs parallel to this axis. Located outside of the two rows of valves x, y, is the perpendicular to the valve receiving bores 2 , 2 'arranged receiving bores 9 , 10 for the pressure accumulator piston 12 , 12 ' effective as part of the storage elements. The pressure medium bores 4 , 13 connect the valve receiving bores 2 of the in the basic position as Auslaßven tile effective electromagnetically closed Ventilelemen te 1 , 1 'with the receiving bores 9 , 10 of the storage elements. A next to the receiving bores 9 , 10 of the storage elements and further receiving bore 11 arranged parallel thereto is connected via a pressure medium bore 15 with the pressure-side pump section of the receiving bore 7 . Hydraulic pressure peaks of the pressure generating element thus reach the damping of the pump noises in the associated receiving bore 11 . The receiving bore 11 is either integrated via a separate cover or sometimes through the lid 21 of the receiving bores 9 , 10 which is designed as a deep-drawn part. In the embodiment shown, the separate cover 21 designed as a screw plug is suitable at the same time for clamping and pressing the cover 21 closing the two receiving bores 9 , 10 , so that fastening means for the cover 21 can be saved. The valve row x facing the storage elements only accepts the electromagnetically closed valve elements (exhaust valves) in the basic position. The second row of valves y combines the valve elements (intake valves) which are electromagnetically opened in the basic position. This results in the image-wise channel guide, after which the pressure medium holes 4 the pressure medium consumer 19 are connected to the valve accommodating bores 2, 2 'of the intake and exhaust valves. Through the shown drilling of the valve receiving body 3 is also seen easily see the cable bushing 26 for the electric motor immediately arranged in the valve receiving body 3 .

Die Fig. 3 zeigt einen auf der Blattfläche gedrehten Ver­ tikalschnitt an der Stelle B-B gemäß Fig. 2, der die Kanal­ führung und die Ausformungen der Aufnahmebohrung 2, 2′, 11 verdeutlicht. Die Ventilaufnahmebohrungen 2, 2′ stehen über eine Druckmittelbohrung 4 mit dem Druckmittelverbraucher 19 (Radbremse) in Verbindung. Die Ventilaufnahmebohrung 2′ weist am Gehäuseboden einen weiteren Kanalabzweig auf, der in den die Aufnahmebohrung 11 mit dem Druckmittelversorger 14 verbindenden Kanal 16 einmündet. Der Kanal 16 liegt zum Zwecke einer ungehinderten Entlüftung der Aufnahmebohrung 11 möglichst weit am Außenrand und damit in erhöhter Lage zur Aufnahmebohrung 11. Ein im Einmündungsbereich des Kanals 16 in die als Dämpfungskammer wirksame Aufnahmebohrung 11 ein­ gesetztes Filterelement 17 verhindert den Transport von Schmutzpartikeln in die Bohrung der Blende 27, die ebenfalls im Kanal 6 angeordnet ist. Wahlweise zu dem in Fig. 2 als Schraubverschluß ausgebildeten Deckel 21 ist dieser in Fig. 3 im Halbschnitt mittels einer selbsteinschneidenden Verbin­ dung sowie in den Ventilaufnahmekörper 3 konisch erweitert ausgeführt. Der härtere Werkstoff des Deckels 21 verdrängt beim Einpressen sodann das weichere Material des Ventilauf­ nahmekörpers 3 (z. B. Aluminium) in die nasenförmig abgesetz­ ten Umfangsnuten des Deckels 21, womit ein fester und flüs­ sigkeitsdichter Sitz des Deckels 21 geschaffen ist. Die ko­ nische Erweiterung des Deckels 21 begünstigt das Entweichen von in der Ausnahmebohrung 11 befindlichen Lufteinschlüssen. Da der zum Verschluß der Aufnahmebohrung 11 vorgesehene Deckel 21 gleichzeitig den als Tiefziehteil kappenförmig ge­ stalteten weiteren Deckel 21 abdichtend zu halten hat, ist vorzugsweise eine als Moosgummi ausgeführte Dichtplatte 29 dazwischengelegt. Der als Tiefziehteil ausgeführte Deckel 21 ist partiell an seiner Anpreßfläche mit Ausdrückungen 28 versehen, die infolge des daraus abgeleiteten Zwischenraums ein Verquetschen und damit eine Beschädigung der Dichtplatte 29 verhindern. Die für das Druckerzeugerelement vorgesehene Aufnahmebohrung 7 befindet sich äußerst kompaktbauend von dem Kanal 16, der Druckmittelbohrung 4 und den Ventilaufnah­ mebohrungen 2, 2′ umgeben im Ventilaufnahmekörper 3, so daß die normalerweise nur in einer vorgelagerten Schnittstelle in der Zeichnung ersichtliche weitere Druckmittelbohrung 15 eine ungehinderte hydraulische Verbindung zur Aufnahmeboh­ rung 11 herstellt. Fig. 3 shows a turned on the blade surface Ver tikalschnitt at the point BB of FIG. 2, the channel guide and the shapes of the receiving bore 2 , 2 ', 11 illustrates. The valve receiving bores 2 , 2 'are connected via a pressure medium bore 4 with the pressure medium consumer 19 (wheel brake). The valve receiving bore 2 'has a further channel branch on the housing base, which opens into the channel 16 connecting the receiving bore 11 with the pressure medium supplier 14 . For the purpose of unimpeded ventilation of the receiving bore 11, the channel 16 is located as far as possible on the outer edge and thus in an elevated position relative to the receiving bore 11 . A set filter element 17 in the opening region of the channel 16 into the receiving bore 11 which acts as a damping chamber prevents the transport of dirt particles into the bore of the diaphragm 27 , which is also arranged in the channel 6 . Optionally to the lid 21 formed in FIG. 2 as a screw closure, this is executed in FIG. 3 in half section by means of a self-tapping connection and in the valve receptacle body 3 expanded conically. The harder material of the cover 21 then displaces the pressed-in, the softer material of the valve body 3 (z. B. aluminum) in the nose-shaped peripheral grooves of the cover 21 , thus creating a firm and liquid-tight seat of the cover 21 is created. The ko African expansion of the lid 21 favors the escape of air pockets located in the exception bore 11 . Since the cover 21 provided for closing the receiving bore 11 has at the same time to keep the cover 21 shaped as a deep-drawn part in the form of a deep-drawn part, a sealing plate 29 designed as cellular rubber is preferably interposed. The cover 21, which is designed as a deep-drawn part, is partially provided on its contact surface with expressions 28 which, as a result of the intermediate space derived therefrom, prevent the sealing plate 29 from being squeezed and thus damaged. The provided for the pressure generator receiving bore 7 is extremely compact from the channel 16 , the pressure medium bore 4 and the Ventilaufnah mebohrungen 2 , 2 'surrounded in the valve receiving body 3 , so that the normally visible only in an upstream interface in the drawing further pressure medium bore 15 an unobstructed hydraulic connection to the tion Bohr 11 creates.

In Fig. 4 ist eine in Fig. 2 gekennzeichnete weitere Schnittstelle C-C in der Seitenansicht skizziert, welche den Anschluß der Druckmittelbohrung 13 an der Saugseite für das Druckerzeugerelement in der Aufnahmebohrung 7 verdeutlicht. Zur ungehinderten Entlüftung der den Druckspeicherkolben 12′ aufweisenden Aufnahmebohrung 10, ist zwischen dem Druckspei­ cherkolben 20 und der zugehörigen Einmündung der Druckmit­ telbohrung 13 eine im wesentlichen scheibenförmige Umlenk­ einrichtung 20 befestigt, die über ihre in Entlüftungsrich­ tung nach oben gerichtete partielle Gehäuseöffnung eine Um­ lenkung der Druckmittelsäule bewirkt. Die Umlenkeinrichtung 20 ist mittels eines Führungszapfens gegen Positionsverände­ rung geschützt und reibschlüssig oder formschlüssig befestigt.In Fig. 4, a further interface CC marked in Fig. 2 is sketched in the side view, which illustrates the connection of the pressure medium bore 13 on the suction side for the pressure generator element in the receiving bore 7 . For unobstructed ventilation of the pressure accumulator piston 12 'receiving bore 10 , between the Druckspei cherkolben 20 and the associated mouth of Druckmit telbohrung 13 a substantially disc-shaped deflection device 20 is attached, the direction of their upward ventilation in the direction of a partial housing opening around the Pressure medium column causes. The deflection device 20 is protected by means of a guide pin against changes in position and is attached in a frictional or positive manner.

In Fig. 5 ist abweichend von den vorangegangenen Ausfüh­ rungsformen die als Volumenschlucker verwendete Aufnahmeboh­ rung 11 ebenfalls, wie die voran beschriebene Speicherele­ mente, konstruktiv mit einem federbelasteten Dämpfungskolben 24 versehen. Der Dämpfungskolben 24 ist im hülsenförmigen Schaft des Deckels 21 abgedichtet geführt, wobei in der Grundposition des Kolbens dieser durch die Federkraft beauf­ schlagt an einem im Schaft des Deckels 21 eingesetzten Sprengring 15 anliegt. Zur Entlüftung und Fortführung von Druckleckage ist der Deckelrand von einer Leckage- und Druckentlastungsbohrung 22 durchdrungen, die von einem am Deckelrand umlaufenden Dichtring 23 normalerweise verschlos­ sen ist. In Folge der variablen Volumenaufnahme der Aufnah­ mebohrung 11 durch den Dämpfungskolben 24, weist der Kanal 16 zusätzlich ein in Richtung des Dämpfungskolbens 24 wirksa­ mes Rückschlagventil 18 auf, womit eine unerwünschte Volu­ menzunahme bei Betätigung des Bremspedals verhindert wird. Der Zulauf von Druckmittel über das in die Ventilaufnahme­ bohrung 2′ eingesetzte Einlaßventil zur Radbremse bleibt von der Schaltstellung des Rückschlagventils 18 unbeeinflußt. Das durch den Dämpfungskolben 24 in der Aufnahmebohrung 11 zwischengespeicherte Druckmittelvolumen verhindert während des Pumpenbetriebs eine die Hauptzylinder-Manschetten schä­ digende Rückstellbewegung der Arbeitskolben.In Fig. 5, deviating from the previous embodiments, the receptacle 11 used as a volume swallow is also, like the storage elements described above, structurally provided with a spring-loaded damping piston 24 . The damping piston 24 is guided in a sealed manner in the sleeve-shaped shaft of the cover 21 , wherein in the basic position of the piston it is struck by the spring force and bears against a snap ring 15 inserted in the shaft of the cover 21 . To vent and continue pressure leakage, the lid edge is penetrated by a leakage and pressure relief bore 22 , which is normally closed by a sealing ring 23 encircling the lid edge. As a result of the variable volume uptake of the receiving bore 11 through the damping piston 24 , the channel 16 additionally has a check valve 18 effective in the direction of the damping piston 24 , thus preventing an undesirable increase in volume when the brake pedal is actuated. The inflow of pressure medium through the bore in the valve receptacle 2 'used inlet valve to the wheel brake remains unaffected by the switching position of the check valve 18 . The temporarily stored by the damping piston 24 in the receiving bore 11 pressure medium volume prevents the master cylinder cuffs damaging restoring movement of the working piston during pump operation.

Eine weitere Ausgestaltungsvariante zur Ausbildung der als Dämpfungskammer wirksamen Aufnahmebohrung 11 (vergleiche Fig. 2, 3 und 5) sieht vor, die Wirkungsmechanismen eines Reflexionsdämpfers mit denen eines Speicherdämpfers zu vereinigen. Dies zeigt beispielhaft die Fig. 6, wonach der die Aufnahmebohrung 11 verschließende Deckel als Speicherdämpfer aus einer Reihenschaltung von einer Membran 30 und einer Topfmanschette 31 gebildet ist, während die Reflexionsdämpfung aus dem bereits beschriebenen Zusammenwirken von zwischengespeicherten Druckmittelvolumen mit Hilfe einer Blende 27 zustande kommt.A further embodiment variant for forming the receiving bore 11 which acts as a damping chamber (compare FIGS. 2, 3 and 5) provides for the mechanisms of action of a reflection damper to be combined with those of a storage damper. This example shows the Fig. 6, according to which the receiving bore, while the return loss is 11 closing lid as a storage damper comprising a series circuit of a membrane 30 and a cup seal 31 is formed from the previously described interaction of cached pressure medium flow by means of a diaphragm 27 into existence.

In einer Zusammenfassung wird nachfolgend die Funktionsweise des nach Fig. 1 bis 6 gezeigten Hydraulikaggregates für ei­ nen Radbremskreis einer schlupfgeregelten Kraftfahrzeug­ bremsanlage erläutert.In a summary, the mode of operation of the hydraulic unit shown in FIGS . 1 to 6 for a wheel brake circuit of a slip-controlled motor vehicle brake system is explained below.

Die Druckmitteleinspeisung in das Hydraulikaggregat erfolgt durch Betätigung des Hauptzylinders (Druckmittelversorger 14), womit Druckmittel in die das Einlaßventil aufnehmende Ventilaufnahmebohrung 2′ und damit zur Radbremse (Druckmit­ telverbraucher 19) gelangt. Die das Einlaßventil mit dem Auslaßventil verbindende Druckmittelbohrung 4 steht eben­ falls unter dem fußkraftproportionalen Druck, während das Auslaßventil die zum Druckspeicherkolben 21 führende Druck­ mittelbohrung 13 sperrt. Mit Beginn der Bremsschlupfregelung treibt der Elektromotor (Antriebselement 6) die Radialkol­ benpumpe (Druckerzeugerelement 5) an, womit das über die Druckmittelbohrung 13 jeweils aus dem Speicherelement (Auf­ nahmebohrung 9, 10) angesaugte Druckmittelvolumen über die Druckmittelbohrung 15 in die Geräuschdämpfungskammer (Auf­ nahmebohrung 11) gefördert wird, um von dort über die Blende 27 den Kanal (16) auf den Tandemhauptzylinder (Druckmittel­ versorger 14) zu wirken, wobei über die Ventilaufnahmeboh­ rungen 2, 2′ die Druckmodulation in Abhängigkeit von der elektromagnetischen Ansteuerung der Einlaß- und Auslaßventi­ le (Ventilelemente 1, 1′) in jeder entsprechend zugehörigen Radbremse (Druckmittelverbraucher 19) erfolgt.The pressure medium feed into the hydraulic unit takes place by actuation of the master cylinder (pressure medium supplier 14 ), with which pressure medium enters the valve receiving bore 2 'receiving the inlet valve and thus to the wheel brake (Druckmit tel consumer 19 ). The connecting the inlet valve with the outlet valve pressure medium bore 4 is just if under the foot force-proportional pressure, while the outlet valve closes the pressure medium bore 13 leading to the pressure accumulator piston 21 . At the beginning of the brake slip control, the electric motor (drive element 6 ) drives the radial piston pump (pressure generator element 5 ), so that the pressure medium volume sucked in via the pressure medium bore 13 from the storage element (on receiving bore 9 , 10 ) via the pressure medium bore 15 into the noise damping chamber (on receiving bore 11 ) is promoted to act from there via the orifice 27, the channel ( 16 ) on the tandem master cylinder (pressure medium supplier 14 ), with the valve receiving holes 2 , 2 'the pressure modulation depending on the electromagnetic control of the inlet and outlet valves (Valve elements 1 , 1 ') in each corresponding associated wheel brake (pressure medium consumer 19 ).
