Abstract

Ein Druckregelventil (20) eines Automatikgetriebes eines Kraftfahrzeugs umfasst ein Gehäuse (28), einen in dem Gehäuse (28) geführten Ventilschieber (32), der mehrere benachbarte Abschnitte (34, 36, 38) aufweist, wobei einer erster Abschnitt (34) einen ersten Durchmesser (D1), ein an diesen anschließender zweiter Abschnitt (36) einen zweiten Durchmesser (D2), der kleiner ist als der erste Durchmesser (D1), und ein an diesen anschließender dritter Abschnitt (38) den ersten Durchmesser (D1) aufweist. Dem ersten Abschnitt (34) ist eine Zulaufdrucköffnung (58), dem zweiten Abschnitt (36) eine Regeldrucköffnung (60), und dem dritten Abschnitt (38) eine Rücklauföffnung (62) zugeordnet. Eine elektromagnetische Betätigungseinrichtung (26) beaufschlagt den Ventilschieber (32) über einen an einer ersten Stirnfläche (50) angreifenden und im Gehäuse (28) druckdicht geführten Kolben (72) in einer ersten Wirkrichtung (78). Eine Beaufschlagungseinrichtung (53) beaufschlagt den Ventilschieber (32) entgegen der ersten Wirkrichtung (78). Es wird vorgeschlagen, dass die erste Stirnfläche (50) des Ventilschiebers (32) einen ersten Druckraum (82) und eine entgegengesetzte zweite Stirnfläche (52) einen zweiten Druckraum (80) begrenzen, die jeweils mit der Regeldrucköffnung (60) fluidverbunden sind.
