Abstract

Two solenoid-operated flow-control valves (11,12) are respectively connected through diodes in reverse-polarity order (13,15) to a DC supply which is reversible (14a,b). By presetting the supply polarity or leaving it unenergised; either, both or neither valve may be operated from only two supply conductors. If three valves are employed with two diodes a set of seven valve-open and valve-closed combinations can be selected by means of only three supply conductors.

Description

Stand der TechnikState of the art

Es ist z. B. aus der DE-OS 16 55 318 bekannt, das Einlaß- und das Auslaßventil eines ABS einseitig parallel an Masse zu legen und das Einlaßventil mit seiner anderen Seite mit einem ersten Ausgang eines Ansteuergerätes und das Auslaßven­ til mit einem zweiten Ausgang des Ansteuergeräts zu verbinden. Zwischen den bei­ den Ansteuerleitungen ist eine Diode derart eingeschaltet, daß ein Signal auf der vom ersten Ausgang kommenden Ansteuerleitung nur das Einlaßventil und ein Signal auf der vom zweiten Ausgang kommenden Ansteuerleitung beide Ventile betä­ tigt.It is Z. B. from DE-OS 16 55 318 known, the inlet and the outlet valve of an ABS on one side parallel to ground and the inlet valve with its other side with a first output of a control device and the Auslaßven til to connect to a second output of the control unit. Between the at a diode is switched on in the control lines such that a signal is on the control line coming from the first output only the inlet valve and a Signal on the control line coming from the second output actuate both valves does.

Vorteile der ErfindungAdvantages of the invention

Im Grunde genommen sind bei der Lösung gemäß dem Stand der Technik drei Lei­ tungsverbindungen notwendig. Bei der Erfindung sind demgegenüber bei zwei Ven­ tilen nur noch zwei Leitungen notwendig, was den Vorteil von weniger Kontakten, geringere Zahl von Kabelbaumleitungen und kleinere Stecker mit geringerer Kon­ taktanzahl hat.Basically there are three Lei in the solution according to the prior art connection necessary. In the invention, in contrast, two Ven only two lines are necessary, which has the advantage of fewer contacts, lower number of wiring harness lines and smaller plugs with lower con has number of measures.

FigurenbeschreibungFigure description

Anhand der Fig. 1 und 2 der Zeichnung werden zwei Ausführungsbeispiele der Erfindung mit zwei Ventilen erläutert.Referring to Figs. 1 and 2 of the drawing two embodiments of the invention are explained with two valves.

Fig. 3 zeigt ein Ausführungsbeispiel mit drei Ventilen und drei Ansteuerleitungen. Fig. 3 shows an embodiment with three valves and three control lines.

In Fig. 1 ist mit 1 ein Einlaßventil (2/2-Magnetventil) und mit 2 ein Auslaß­ ventil (3/2-Magnetventil) eines ABS bezeichnet. Mit dem Auslaßventil 3 liegt eine Diode in Reihe. Wird an den Ansteuerklemmen 4a und 4b die gleiche Span­ nung, also z. B. die Spannung 0 angelegt, so bleiben die Ventile in ihrer Aus­ gangsstellung und es ist Druckaufbau möglich. Wird an die Klemme 4a der positive Pol der Gleichspannungsquelle gelegt und an Klemme 4b der negative Pol, dann kann wegen der Sperrwicklung der Diode 3 nur das Ventil 1 ansprechen. Der vor­ handene Druck wird dann gehalten. Werden die Pole der Gleichspannungsquelle da­ gegen vertauscht, dann entfällt die Sperrwicklung der Diode 3 und beide Ventile sprechen an. Der Bremsdruck wird abgebaut.In Fig. 1, 1 denotes an inlet valve ( 2/2 solenoid valve) and 2 an outlet valve ( 3/2 solenoid valve) of an ABS. With the outlet valve 3 is a diode in series. Is at the control terminals 4 a and 4 b the same voltage, so z. B. the voltage is applied to 0 , the valves remain in their starting position and it is possible to build up pressure. If the positive pole of the DC voltage source is connected to terminal 4 a and the negative pole to terminal 4 b, then only valve 1 can respond due to the reverse winding of diode 3 . The existing pressure is then held. If the poles of the DC voltage source are interchanged, the blocking winding of the diode 3 is omitted and both valves respond. The brake pressure is reduced.

Fig. 2 unterscheidet sich von Fig. 1 dadurch, daß das Auslaßventil 12 derart ausgebildet ist, daß es in seiner Schaltstellung Druckabbau die Haltefunktion des Einlaßventils 11 nicht benötigt und dadurch daß auch mit dem Einlaßventil 11 eine gegenüber der Diode 13 umgekehrt gepolte Diode 15 in Reihe liegt. Wird der positiven Polung der Gleichspannungsquelle an die Klemme 14a gelegt und der negative an Klemme 14b, so wird nur das Ventil 11 geschaltet. Bei umge­ kehrter Polung wird wegen der nun vorhandenen Sperrwirkwicklung der Diode 15 nur das Auslaßventil 12 betätigt. Fig. 2 differs from Fig. 1 in that the outlet valve 12 is designed such that it does not need the holding function of the inlet valve 11 in its switching position pressure reduction and in that also with the inlet valve 11 a diode 15 reversely polarized with respect to the diode 13 in Row lies. If the positive polarity of the DC voltage source is connected to terminal 14 a and the negative one to terminal 14 b, only valve 11 is switched. When the polarity is reversed, only the outlet valve 12 is actuated because of the now existing blocking active winding of the diode 15 .

In Fig. 3 sind zwei Einlaßventile 31 und 32 und ein Auslaßventil parallel an eine Leitung 1′ angeschaltet die andere Klemme der Einlaßventile 31 und 32 sind mit Ansteuerleitungen 2′ und 3′ verbunden. Die zweite Klemme des Anlaßventils 33 ist über Dioden 34 mit den Ansteuerleitungen 2′ und 3′ verbunden. Dieses Stell­ glied könnte bei einer Luftfederung eines Kraftfahrzeuges Anwendung finden, wo­ bei das Ventil in seiner Ausgangslage mit einer Druckquelle verbunden ist und bei Ansteuerung an eine Drucksenke angeschaltet wird. Der andere Ausgang des An­ steuerventils ist über die beiden in Ausgangslage geschlossenen Einlaßventile mit der Luftfederung der beiden Wagenseiten verbunden.In Fig. 3, two intake valves 31 and 32 and an exhaust valve are connected in parallel to a line 1 ', the other terminal of the intake valves 31 and 32 are connected to control lines 2 ' and 3 '. The second terminal of the starter valve 33 is connected via diodes 34 to the control lines 2 'and 3 '. This actuator could be used in an air suspension of a motor vehicle, where the valve is connected to a pressure source in its starting position and is switched on when actuated to a pressure sink. The other output of the control valve is connected to the air suspension of the two sides of the car via the two inlet valves closed in the initial position.

Die Tabelle der Fig. 3 zeigt die Wirkungsweise der Schaltung bei verschiedenen Ansteuerungen mit + oder - Signalen auf den einzelnen Ansteuerleitungen. Rechts ist aufgelistet, welche Ventile ansprechen. Bei den letzten drei Zeilen wird Druck abgebaut, bei den drei Zeilen davor Druck aufgebaut.The table in FIG. 3 shows the mode of operation of the circuit in the case of various controls with + or - signals on the individual control lines. On the right is listed which valves respond. Pressure is released in the last three lines, pressure is built up in the three lines before.
