A pressure-supplying arrangement is proposed which is essentially composed of an electric motor (3), a pump (1) and an accumulator (2). At least the pump (1) and the accumulator (2) are assembled in a common housing (4) in order to reduce pressure vibrations and noise. The pressure-supplying arrangement is intended for hydraulic servo brakes and is especially suitable for such with anti-lock devices. <IMAGE>

Description

DruckbeschaffungseinrichtungPrint procurement facility

Stand der Technik Die Erfindung geht aus von einer Druckbeschaffungseinrichtung nach der Gattung des Hauptanspruchs. Eine derartige Druckbeschaffungseinrichtung ist bekannt (DE-GM 76 07 737).PRIOR ART The invention is based on a print procurement device according to the genre of the main claim. Such a print procurement facility is known (DE-GM 76 07 737).

Dieser bekannten Einrichtung liegt die Aufgabe zugrunde, eine kompakte Baueinheit zu schaffen. Dabei ist aber die Lösung so getroffen, daß Pumpe und Speicher getrennte Bauteile sind.This known device is based on the task of a compact To create structural unit. But the solution is such that the pump and the memory are separate components.

Es ist zwar ebenfalls bereits bekannt, eine Pumpe unmittelbar mit einer Dämpferkammer zusammen zu bauen, um Druckschwingungen und Geräusche zu vermindern (DE-OS 27 03 761).It is also already known to use a pump directly to build a damper chamber together to reduce pressure vibrations and noise (DE-OS 27 03 761).

Eine solche Bauart hat aber einen getrennt angeordneten Speicher, so daß sie umständlich und teuer ist.However, such a design has a separately arranged memory, so that it is cumbersome and expensive.

Vorteile der Erfindung Die Druckbeschaffungseinrichtung mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegneüber den Vorteil, daß der unmittelbare Zusammenbau von Pumpe und Speicher die Dämpfung von Druckschwingungen und des Geräuschpegels innerhalb dieser Kombination ermöglicht. Die Verwendung zusätzlicher Bauelemente erübrigt sich deshalb.Advantages of the Invention The print procurement device with the characterizing Features of the main claim has the advantage that the immediate Assembly of pump and accumulator, damping of pressure oscillations and the noise level within this combination enables. The use of additional components is unnecessary therefore.

Weitere vorteilhafte Merkmale der Erfindung ergeben sichaus der Beschreibung und aus den Unteransprüchen.Further advantageous features of the invention emerge from the description and from the subclaims.

Zeichnung Ein Ausführungsbeispiel der Erfindung ist in der Zeåchnung dargestellt und in der nachfolgenden Beschreibung näher erläutert.Drawing An embodiment of the invention is in the drawing and explained in more detail in the following description.

Beschreibung des Ausführungsbeispiels Eine Druckbeschaffungseinrichtung besteht im wesentlichen aus einer Pumpe 1, einem Speicher 2 und einem die Pumpe 1 antreibenden Elektromotor 3. Für die Pumpe 1- und den Speicher 2 ist ein gemeinsames Gehäuse 4 vorgesehen, indem sie direkt zusammengebaut angeordnet sind, und an dieses Gehäuse 4 ist der Elektromotor 3 angeflanscht.Description of the Embodiment A print acquisition device consists essentially of a pump 1, a memory 2 and a pump 1 driving electric motor 3. For the pump 1 and the memory 2 is a common one Housing 4 provided by being arranged directly assembled, and attached to this Housing 4 is flanged to the electric motor 3.

Das Gehäuse 4 nimmt eine Antriebswelle 5 auf, die vom Motor 3 über eine Kupplung 6 angetrieben wird und die einen Exzenter 7 trägt, der einen federbelasteten Pumpenkolben 8 antreibt. Ein einseitig von dem Pumpenkolben 8 begrenzter Pumpenarbeitsraum 9 ist im unteren Totpunkt des Pumpenkolbens 8 an eine Saugleitung 10 angeschlossen. Diese Verbindung wird beim Förderhub des Pumpenkolbens 8 von dessen Mantelfläche überfahren und abgeriegelt.The housing 4 accommodates a drive shaft 5, which is driven by the motor 3 a clutch 6 is driven and which carries an eccentric 7 which has a spring-loaded Pump piston 8 drives. A pump working space bounded on one side by the pump piston 8 9 is connected to a suction line 10 at the bottom dead center of the pump piston 8. This connection is made during the delivery stroke of the pump piston 8 by its lateral surface run over and cordoned off.

Am Ende des Pumpenarbeitsraumes 9 sitzt ein Druckventil 12, das gefördertes Druckmittel über einen Gehäusekanal 11 in eine Speicherkammer 13 des Speichers 2 gelangen läßt. Die Speicherkammer 13 wird durch einen Kolben 14-als beweglicher Wand begrenzt, auf dessen Rückseite in einer Federkammer 15 Gas als Feder einwirkt. Jedoch kann in der-Federkammer 15 auch eine Stahlfeder vorgesehen sein, und es kann der Kolben 14 auch als Membran oder Blase ausgebildet sein. Der Speicher 2 ist, wie gezeichnet, senkrecht zur Achse des Pumpenkolbens 8 angeordnet, er kann aber auch gleichachsig zum Pumpenkolben 8 vorgesehen sein.At the end of the pump working space 9 there is a pressure valve 12, the pumped Pressure medium via a housing channel 11 into a storage chamber 13 of the storage unit 2 can get. The storage chamber 13 is made more movable by a piston 14 Wall limited, on the back of which acts in a spring chamber 15 gas as a spring. However a steel spring can also be provided in the spring chamber 15, and the Piston 14 can also be designed as a membrane or bladder. The memory 2 is how drawn, arranged perpendicular to the axis of the pump piston 8, but it can also be provided coaxially to the pump piston 8.

Ein Ausgang des Speichers führt über eine Drossel 16 zu einer Förderleitung 17, an die ein Verbraucher angeschlossen ist. Parallel zur Drossel 16 ist ein Rückschlagventil 18 angeordnet, das eine Kugel 19 als Schließkörper hat, die von einer Feder 20 gegen einen Ventilsitz 21 gedrückt wird. Es ist aber als Alternative auch möglich, anstatt der Belastung des Kugelschließkörpers 19 durch die Feder 20 einen Kolben 22 zu verwenden und diesen über eine Zweigleitung 23 dem Druck in der Förderleitung 17 auszusetzen und mit einem Stößel 24 auf den Kugelschließkörper 19 einwirken zu lassen. Diese Alternative ist in die Zeichnung gestrichelt eingezeichnet. Sie hat den Vorteil, daß ein durch das Rückschlagventil 18 entstehender Druckverlust geringer ist.An output of the memory leads via a throttle 16 to a delivery line 17 to which a consumer is connected. A check valve is parallel to the throttle 16 18 arranged, which has a ball 19 as a closing body, which by a spring 20 against a valve seat 21 is pressed. But it is also possible as an alternative instead of the loading of the ball closure body 19 by the spring 20 to use a piston 22 and to expose it to the pressure in the delivery line 17 via a branch line 23 and to act on the ball locking body 19 with a plunger 24. These The alternative is shown in dashed lines in the drawing. She has the advantage that a pressure loss caused by the check valve 18 is lower.

Der Speicher-Kolben 14 arbeitet mit einem in der Speicherkammer 13 angeordneten, gleichachsig zum Kolben 14 liegenden Schalterstößel 25 zusammen, der eine Gehäusewand 26 abgedichtet durchdringt und der auf einen elektrischen Schalter einwirken kann.The storage piston 14 works with one in the storage chamber 13 arranged, coaxially to the piston 14 lying switch plunger 25 together, the a housing wall 26 penetrates sealed and the on an electrical switch can act.

Wirkungsweise Der Elektromotor 3 treibt die Pumpe 1 an, und diese erzeugt im Pumpenarbeitsraum 9 einen Pumpendruck in einem Druckmittel. Das Druckmittel gelangt über das Druckventil 12 in den Gehäusekanal 11, der unmittelbar zu dem Speicher 2 führt. Die bei der Arbeit der Pumpe 1 entstehenden Druckstöße und Druckschwingungen werden in der vom Druckmittel unmittelbar erreichten Speicherkammer 13 gedämpft und geglättet. Außerdem werden eventuell-auftretende Geräusche ebenfalls gedämpft.Mode of operation The electric motor 3 drives the pump 1, and this generates a pump pressure in a pressure medium in the pump working space 9. The pressure medium reaches the pressure valve 12 in the housing channel 11, which is directly leads to the memory 2. The pressure surges that occur when the pump 1 is working and pressure oscillations are in the storage chamber directly reached by the pressure medium 13 dampened and smoothed. In addition, any noises that may occur are also muffled.

Das Rückschlagventil 18 weist einen bestimmten Öffnungsdruck auf und hat die Aufgabe, einem an die Förderleitung 17 angeschlossenen Verbraucher Druckmittel relativ unverzögert zur Verfügung zu stellen, wenn eine größere -Druckmittelmenge benötigt wird.The check valve 18 has a certain opening pressure and has the task of supplying pressure medium to a consumer connected to the delivery line 17 to be made available relatively instantaneously when a larger amount of pressure medium is needed.

Die Bewegung des Speicherkolbens 14 beim Füllen und Entleeren des Speichers wird zum Betätigen des Schalters 27 verwendet, der den Elektromotor 3 ein- und au-sschaltet-und/ oder bei zu niedrigem Speicherdruck eine-Warnlampe ansteuert.The movement of the storage piston 14 when filling and emptying the The memory is used to operate the switch 27 that controls the electric motor 3 switches on and off and / or triggers a warning lamp when the accumulator pressure is too low.

Die erfindungsgemäße Druckbeschaffungseinrichtung ist für hydraulische Servobremsen bestimmt und eignet sich besonders für solche mit Blockierschutzeinrichtungen, weil dort kompakte~Bauelemente erforderlich sind und Geräusche vermieden werden müssen.The pressure acquisition device according to the invention is for hydraulic Servo brakes are intended and particularly suitable for those with anti-lock devices, because compact components are required there and noises are avoided have to.
