Patentanspruch:Claim: Magnetisch betätigtes Plattenrückschlagventil für hydraulische und pneumatische Anlagen, insbesondere für Verdrängerpumpen, mit einem plattenförmigen Ventilverschlußteil, das der Mündung eines Zuflußkanals zugeordnet ist, so daß bei einem bestimmten Druck in dem Zuflußkanal die Ventilplatte von ihrem Sitz abgehoben und der Zuflußkanal mit einem Abflußkanal verbunden wird, d a durch gekennzeichnet, daß das Ventilgehäuse in ein erstes, ferromagnetisches, den Znflußkanal (2) und den Ventilsitz enthaltendes Gehäuseteil (3) und ein zweites, nicht magnetisierbares und eine ringförmige Nut (4) mit einer Ausnehmung (5) für die Ventilplatte (1) als Abflußkanal enthaltendes zweites Gehäuseteil (6) unterteilt ist und die Ventilplatte (1) ein Magnet ist.Magnetically operated plate check valve for hydraulic and pneumatic systems, in particular for positive displacement pumps, with a plate-shaped valve closure part, which is the mouth of a Inflow channel is assigned, so that at a certain pressure in the inflow channel, the valve plate lifted from their seat and the inflow channel is connected to an outflow channel, d a through characterized in that the valve housing in a first, ferromagnetic, the Znflußkanal (2) and the valve seat containing housing part (3) and a second, non-magnetizable and one a second annular groove (4) with a recess (5) for the valve plate (1) as a drainage channel Housing part (6) is divided and the valve plate (1) is a magnet. Die Erfindung betrifft ein magnetisch betätigtes Plattenrückschlagveniil für hydraulische und pneumatische Anlagen, insbesondere für Verdrängerpumpen, nach dem Oberbegriff des Patentanspruches.The invention relates to a magnetically operated plate check valve for hydraulic and pneumatic Systems, in particular for positive displacement pumps, according to the preamble of the patent claim. Derartige Ventile sollen ein gutes Ansprechen auf hochfrequente Förderstrom- oder Druckimpulse sowie ein leichtes Ansprechen auf kleine StromimpuLse oder kleine Druckdifferenzen sicher gewährleisten. Durch die FR-PS 15 07 256 ist ein solches Ventil bekannt, das im wesentlichen aus einem scheibenförmigen Ventilplättchen aus ferroniagnetischem Werkstoff und einem ringförmigen Magneten besteht, die beide in entsprechenden Gehäuseteilen angeordnet sind. Bei einem anderen bekannten Plattenventil nach der US-PS 26 67 895 ist die Ventilscheibe als Magnet ausgebildet. Hierbei wird die Schließkraft dur.:h einen zweiten > Magneten erzeugt, der ein zusätzliches Bauteil darstellt.Such valves should respond well to high-frequency flow or pressure pulses as well ensure easy response to small current impulses or small pressure differences. By the FR-PS 15 07 256 such a valve is known, which consists essentially of a disc-shaped valve plate consists of ferroniagnetischem material and a ring-shaped magnet, both in corresponding Housing parts are arranged. In another known plate valve according to the US-PS 26 67 895, the valve disc is designed as a magnet. Here, the closing force is dur.:h a second > Magnet generated, which represents an additional component. Der Erfindung liegt die Aufgabe zugrunde, ein magnetisch betätigtes Platienrückschlagventil zu schaffen, das neben den beschriebenen vorteilhaften Eigenschaften einen sehr einfachen Aufbau mit nur wenig ίο Bauteilen aufweist.The invention is based on the object of creating a magnetically actuated plate check valve, In addition to the advantageous properties described, this has a very simple structure with only a little ίο has components. Diese Aufgabe wird gemäß der vorliegenden Erfindung durch die im kennzeichnenden Teil des Patentanspruches angegebenen Merkmale gelöst.This object is achieved according to the present invention by the in the characterizing part of Patent claim specified features solved. Nachstehend wird die Erfindung anhand eines in einer Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Es zeigtThe invention is described in greater detail below with the aid of an exemplary embodiment shown in a drawing explained. It shows Fig. 1 einen Querschnitt durch das Plattenrückschlagventil, 1 shows a cross section through the plate check valve, Fig. 2 den Schnitt durch das Ventil nach der Linie H-Il der Fig. 1.FIG. 2 shows the section through the valve along the line II-II in FIG. 1. Ein scheibenförmiger Magnet ist als Ventilplatte I ausgebildet, die einen Kanal 2 in einem Gehäuseteil 3 aus feriOniagnetischem Werkstoff öldicht abschließt. Sobald der Druck des Fördermittel in dem Kanal 2 einen bestimmten Wert überschreitet, wird die Ventilplatte t von ihrem Sitz auf dem ferromagnetischen Gehäuseteil 3 abgehoben. Dadurch wird der Kanal 2 an eine ringförmige Nut 4 mit jeweils einer Ausnehmung 5 für die Ventilplatte 1 in einem zweiten Gehäuseteil 6 aus nicht magnetisierbarem Material angeschlossen. Die Ausnehmung 5 dient zur Führung der Ventilplatte 1 und ist so dimensioniert, daß bei einer entsprechenden Druckminderung im Kanal 2 die Ventilplatte t wieder fest und öldicht auf dem Rand des Kanals 2 gehalten werden kann.A disk-shaped magnet is designed as a valve plate I, which has a channel 2 in a housing part 3 made of feriOniagnetic material seals oil-tight. As soon as the pressure of the conveying medium in channel 2 exceeds a certain value, the valve plate t lifted from its seat on the ferromagnetic housing part 3. This turns channel 2 on an annular groove 4, each with a recess 5 for the valve plate 1 in a second housing part 6 non-magnetizable material connected. The recess 5 is used to guide the valve plate 1 and is dimensioned so that with a corresponding pressure reduction in channel 2, the valve plate t again can be held firmly and oil-tight on the edge of the channel 2.
