Hydraulic switch valve has a bypass at the valve slide, near the tank connection, to carry the pressure medium to the piston/cylinder to support the action of the return spring for fast switch times using small electromagnets

The hydraulic switch valve (1) has a bypass (24) at the valve slide (16), near the tank connection (4). It carries the pressure medium to the piston/cylinder unit (26) to support the return forces of the return spring (7). A choke is between the tank and the tank connection. The cylinder is formed f...

description	The hydraulic switch valve (1) has a bypass (24) at the valve slide (16), near the tank connection (4). It carries the pressure medium to the piston/cylinder unit (26) to support the return forces of the return spring (7). A choke is between the tank and the tank connection. The cylinder is formed from the end of the valve sleeve (15) away from the electromagnets (6), and the piston is formed at the end of the valve slide away from the electromagnets. Ein Schaltventil mit in einer Ventilhülse angeordnetem Ventilschieber, dem ein Elektromagnet zugeordnet ist, der den Ventilschieber anzutreiben vermag, und dem weiterhin eine Rückstellfeder zugeordnet ist, wobei die Ventilhülse einen Pumpenanschluß, einen Tankanschluß und einen Arbeitsanschluß aufweist, soll so verbessert werden, dass das Schaltventil für große Durchflussleistungen und für große Druckdifferenzen so ausgestaltet wird, dass trotz Verwendung kleiner Elektromagnete sehr schnelle Schaltzeiten erreicht werden. Dazu wird vorgeschlagen, daß der Ventilschieber im Bereich des Tankanschlusses eine Bypass aufweist, über den Druckmittel einer die Rückstellfeder in der Rückstellkraft unterstützenden Kolben-Zylinder-Einheit zuführbar ist.
