Abstract

The impact-type valve lies between the water inlet (1) and outlet (2) of an appliance, with the control chamber (3) having a membrane (4) pressed by the valve disc (5) against the valve seat (6). The disc has control openings(12) on the inlet side and others (14) on the outlet side. The inlet side openings are spiral or zigzag grooves.

Description

Die Erfindung betrifft ein schlagartig, insbesondere elektromagnetisch verschließ­ bares Ventil, vorzugsweise zur Anordnung in Wasserzuleitungen von Haushaltsge­ räten mit einem Wassereinlaß, einem Wasserauslaß und einer zwischen diesen angeordneten Steuerkammer, in der zum Verschluß eine Membran durch einen Ventilteller gegen einen Ventilsitz gepreßt wird, wobei der Ventilteller mit einlaß­ seitigen Steueröffnungen und auslaßseitigen Steueröffnungen versehen ist.The invention relates to an abrupt, in particular electromagnetic closure bares valve, preferably for arrangement in water supply lines from household appliances advise with a water inlet, a water outlet and one between them Arranged control chamber in which a membrane is closed by a Valve plate is pressed against a valve seat, the valve plate with inlet side control openings and outlet-side control openings is provided.

Bei den vorgenannten Ventilen ist es bekannt, als einlaßseitige Steueröffnung(en) im Ventilteller eine oder mehrere dezentrale Bohrungen oder Steuerkerben in axi­ aler Richtung vorzusehen. Als auslaßseitige Steueröffnung fungiert eine zentrale Steuerbohrung, welche durch einen elektromagnetisch hebbaren Verschluß abge­ sperrt wird. Das Magnetventils öffnet bei Stromzufuhr auf eine Magnetspule, der Verschluß wird angehoben. Hierdurch wird eine Steuerkammer druckentlastet, da die zentrale Steuerbohrung einen größeren Querschnitt als die dezentralen auf­ weist. Die Druckentlastung führt zu einer Anhebung der Membran, welche hier­ durch den Wasserweg freigibt.In the aforementioned valves, it is known to act as an inlet-side control opening (s) one or more decentralized bores or control notches in axi in the valve disk in all directions. A central control opening acts as the outlet Control bore, which abge through an electromagnetically liftable closure is blocked. The solenoid valve opens when power is supplied to a solenoid which The lock is raised. This relieves pressure in a control chamber since the central control bore has a larger cross section than the decentralized ones points. The pressure relief leads to an increase in the membrane, which here released through the waterway.

Beim Verschluß der zentralen Steuerbohrung durch Abschalten der Stromzufuhr auf die Magnetspule wird die Steuerkammer über die dezentralen Steuerbohrun­ gen gefüllt und die Membran bewegt sich zum Ventilsitz. Das Ventil schließt. Je nach Geschwindigkeit dieser Bewegung, insbesondere während des letzten Teils vor dem Aufsetzen der Membran auf dem Ventilsitz entsteht ein Druckstoß in der Wasserleitung. Dieser verursacht starke Schwingungen und hierdurch Geräusche.When the central control hole is closed by switching off the power supply the control chamber is placed on the solenoid via the decentralized control bore filled and the membrane moves to the valve seat. The valve closes. Each according to the speed of this movement, especially during the last part before the membrane is placed on the valve seat, a pressure surge occurs in the Water pipe. This causes strong vibrations and therefore noise.

Um den Druckstoß zu verringern ist es bekannt, den Querschnitt der einlaßseitigen Steueröffnungen zu verringern. Dies kann jedoch aufgrund von Kalkablagerungen oder Verschmutzungen zu deren Verstopfung führen. In order to reduce the pressure surge, it is known to use the cross section of the inlet side Reduce tax openings. However, this can be due to lime deposits or contamination lead to their constipation.  

Der Erfindung liegt daher das Problem zugrunde, eine verbesserte Maßnahme zur Vermeidung von Druckstößen beim Schließen der eingangs genannten Ventile zu offenbaren. Erfindungsgemäß wird dieses Problem mit den im Patentanspruch 1 angegebenen Merkmalen gelöst.The invention is therefore based on the problem of an improved measure for Avoidance of pressure surges when closing the valves mentioned at the beginning reveal. According to the invention, this problem is solved with that in claim 1 specified features solved.

Der mit der Erfindung erreichbare Vorteil besteht in einer Verlängerung der einlaß­ seitigen Steueröffnung. Hierdurch erhöht sich deren Strömungswiderstand und es kommt zum Verlangsamen der Membranbewegung. Gleichzeitig wird der Quer­ schnitt der Öffnung beibehalten und so einem Verstopfen vorgebeugt.The advantage achievable with the invention is an extension of the inlet sided control opening. This increases their flow resistance and it the membrane movement slows down. At the same time the cross Cut the opening and thus prevent clogging.

Ein Ausführungsbeispiel der Erfindung ist anhand einer Zeichnung rein schema­ tisch dargestellt und wird nachstehend näher erläutert. Die Figur zeigt ein erfin­ dungsgemäß aufgebautes Magnetventil im Querschnitt. Dabei ist zwischen dem Einlaßstutzen (1) und dem Auslaßstutzen (2) eine Steuerkammer (3) angeordnet. Die Steuerkammer (3) nimmt als Verschlußorgan eine Membran (4) auf, welche über einen Ventilteller (5) gegen den Ventilsitz (6) bewegbar ist. Die Bewegung des Ventiltellers (5) erfolgt durch den Strömungsdruck des in die Steuerkam­ mer (3) eintretenden Wassers in Abhängigkeit von der Stellung eines elektromag­ netisch betätigten Verschlusses (7; 8; 9).An embodiment of the invention is shown purely schematically using a drawing and is explained in more detail below. The figure shows a solenoid valve according to the invention constructed in cross section. A control chamber ( 3 ) is arranged between the inlet connector ( 1 ) and the outlet connector ( 2 ). The control chamber ( 3 ) receives a diaphragm ( 4 ) as a closure element, which can be moved against the valve seat ( 6 ) via a valve disk ( 5 ). The movement of the valve plate ( 5 ) takes place through the flow pressure of the water entering the control chamber ( 3 ) depending on the position of an electromagnetically actuated closure ( 7 ; 8 ; 9 ).

In seiner in der Figur gezeigten Schließstellung tritt Wasser durch den Einlaßstut­ zen (1) und durch Einlaßlöcher (10) in der Membran (4) in eine ringförmige Kam­ mer (11) zwischen Membran (4) und Ventilteller (5) ein. Von dort gelangt das Wasser über eine spiralförmige Steuerkerbe (12) in den oberen Bereich (13) der Steuerkammer (3). Der Wasserdruck preßt die Oberseite des Ventiltellers (5) nach unten gegen die Membran (4), welche sich gegen den Ventilsitz (6) legt. Hierdurch wird der Auslaßstutzen (2) geschlossen.In its closed position shown in the figure, water enters through the inlet pipe ( 1 ) and through inlet holes ( 10 ) in the membrane ( 4 ) into an annular chamber ( 11 ) between the membrane ( 4 ) and valve disk ( 5 ). From there, the water reaches the upper area ( 13 ) of the control chamber ( 3 ) via a spiral control notch ( 12 ). The water pressure presses the top of the valve plate ( 5 ) down against the membrane ( 4 ), which lies against the valve seat ( 6 ). This closes the outlet port ( 2 ).

Bei Stromzufuhr wird der Anker (8) durch die Magnetspule (7) angezogen und der Verschluß (9) angehoben. Auf diese Weise wird die zentrale Steuerbohrung (14) geöffnet. Da deren Strömungsquerschnitt größer als der der Steuerkerbe (12) ist, richtet sich der Wasserdruck gegen die Unterseite des Ventiltellers (5). Hierdurch werden Ventilteller (5) und Membran (4) angehoben, der Auslaßstutzen wird frei­ gegeben. When power is supplied, the armature ( 8 ) is attracted by the magnetic coil ( 7 ) and the closure ( 9 ) is raised. In this way, the central control bore ( 14 ) is opened. Since their flow cross-section is larger than that of the control notch ( 12 ), the water pressure is directed against the underside of the valve plate ( 5 ). As a result, the valve plate ( 5 ) and membrane ( 4 ) are raised, the outlet port is released.

Beim erneuten Schließen des Ventils verlangsamt der erhöhte Strömungswider­ stand der spiralförmigen Steuerkerbe (12) die Membranbewegung (4). Hierdurch wird der Druckstoß gemindert.When the valve is closed again, the increased flow resistance slows down the spiral control notch ( 12 ), the membrane movement ( 4 ). This reduces the pressure surge.
