Abstract

A hydraulic switching assembly for a motor vehicle, having a hydraulic pump (1) which guides a hydraulic medium from a reservoir (2) via hydraulic lines (3) and at least one magnetic valve assembly (4) including a magnetically actuatable switching valve (5), to a switching element (6) in order to hydraulically actuate the switching element (6) between two switching positions. A pressure accumulator (7) and a first check valve (8a) are mounted in a supply line (3a) upstream of the switching valve (5) in order to realize a reliable temporary supply of oil pressure to the switching element (6).
