Description
Stand der TechnikState of the art
Die Erfindung geht aus von einem Rückschlagventil nach den Merkmalen des Gattungsbegriffs des Hauptanspruchs.The invention relates to a check valve according to the features of the preamble of the main claim.

Vorteile der ErfindungAdvantages of the invention
Das Rückschlagventil nach den Merkmalen des Anspruchs 1 weist erfindungsgemäß einen aus Blech tiefgezogenen, kappenförmigen Ventilsitzträger mit einem Mittelloch auf, an dem der Ventilsitz ausgebildet ist. Dieser Ventilsitzträger ist an einer Stirnseite des Ventilgehäuses befestigt. Der Vorteil dieser Ausführung ist, dass der mechanisch beaufschlagte Ventilsitz damit aus einem verschleißfesteren Material als das Ventilgehäuse hergestellt ist, ohne dadurch den Herstellungsaufwand bzw. die kompakte oder kostengünstige Bauweise eines Rückschlagventils nach den gattungsbildenden Merkmalen des Anspruchs 1 nennenswert zu beeinflussen.The check valve according to the features of claim 1 according to the invention comprises a deep-drawn from sheet metal, cap-shaped valve seat carrier with a center hole on which the valve seat is formed. This valve seat carrier is attached to an end face of the valve housing. The advantage of this design is that the mechanically acted valve seat is thus made of a more wear-resistant material than the valve housing, without thereby affecting the production cost or the compact or inexpensive construction of a check valve according to the generic features of claim 1 appreciably.
Die Unteransprüche haben vorteilhafte Ausgestaltungen und Weiterbildungen der im Hauptanspruch angegebenen Erfindung zum Gegenstand.The dependent claims have advantageous refinements and developments of the invention specified in the main claim for the subject.
Das erfindungsgemäße Rückschlagventil ist insbesondere als Ein- und/oder Auslassventil für eine Kolbenpumpe einer beispielsweise schlupfgeregelten, hydraulischen Fahrzeugbremsanlage vorgesehen (Anspruch 6).The check valve according to the invention is provided in particular as an inlet and / or outlet valve for a piston pump, for example, a slip-controlled, hydraulic vehicle brake system (claim 6).
Die Kolbenpumpe ist insbesondere als Pumpe in einer Bremsanlage eines Fahrzeugs vorgesehen und wird beim Steuern des Drucks in Radbremszylindern verwendet. Je nach Art der Bremsanlage werden für derartige Bremsanlagen die Kurzbezeichnungen ABS bzw. ASR bzw. FDR bzw. EHB verwendet. In der Bremsanlage dient die Pumpe beispielsweise zum Rückfördern von Bremsflüssigkeit aus einem Radbremszylinder oder aus mehreren Radbremszylindern in einen Hauptbremszylinder (ABS) und/oder zum Fördern von Bremsflüssigkeit aus einem Vorratsbehälter in einen Radbremszylinder oder in mehrere Radbremszylinder (ASR bzw. FDR bzw. EHB). Die Pumpe wird beispielsweise bei einer Bremsanlage mit einer Radschlupfregelung (ABS bzw. ASR) und/oder bei einer als Lenkhilfe dienenden Bremsanlage (FDR) und/oder bei einer elektrohydraulischen Bremsanlage (EHB) benötigt. Mit der Radschlupfregelung (ABS bzw. ASR) kann beispielsweise ein Blockieren der Räder des Fahrzeugs während eines Bremsvorgangs bei starkem Druck auf das Bremspedal (ABS) und/oder ein Durchdrehen der angetriebenen Räder des Fahrzeugs bei starkem Druck auf das Gaspedal (ASR) verhindert werden. Bei einer als Lenkhilfe (FDR) dienenen Bremsanlage wird unabhängig von einer Betätigung des Bremspedals bzw. Gaspedals ein Bremsdruck in einem oder in mehreren Radbremszylindern aufgebaut, um beispielsweise ein Ausbrechen des Fahrzeugs aus der vom Fahrer gewünschten Spur zu verhindern. Die Pumpe kann auch bei einer elektrohydraulischen Bremsanlage (EHB) verwendet werden, bei der die Pumpe die Bremsflüssigkeit in den Radbremszylinder bzw. in die Radbremszylinder fördert, wenn ein elektrischer Bremspedalsensor eine Betätigung des Bremspedals erfaßt oder bei der die Pumpe zum Füllen eines Speichers der Bremsanlage dient.The piston pump is provided in particular as a pump in a brake system of a vehicle and is used in controlling the pressure in wheel brake cylinders. Depending on the type of brake system, the abbreviations ABS or ASR or FDR or EHB are used for such brake systems. In the brake system, the pump is used, for example, for returning brake fluid from a wheel brake cylinder or several wheel brake cylinders in a master cylinder (ABS) and / or for delivering brake fluid from a reservoir into a wheel brake cylinder or into several wheel brake cylinders (ASR or FDR or EHB). , The pump is required, for example, in a brake system with a wheel slip control system (ABS or ASR) and / or in a brake system (FDR) serving as power steering and / or in an electrohydraulic brake system (EHB). With the wheel slip control (ABS or ASR), for example, a blocking of the wheels of the vehicle during a braking operation with heavy pressure on the brake pedal (ABS) and / or a spin of the driven wheels of the vehicle with strong pressure on the accelerator pedal (ASR) can be prevented , When used as power steering (FDR) brake system, regardless of an operation of the brake pedal or accelerator pedal, a brake pressure is built in one or more wheel brake cylinders to prevent, for example, a breaking out of the vehicle from the driver desired track. The pump may also be used in an electrohydraulic brake system (EHB) in which the pump delivers the brake fluid to the wheel brake cylinder (s) when an electrical brake pedal sensor detects an operation of the brake pedal or the pump to fill a brake system reservoir serves.
