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).
Claims18
A hydraulic switching assembly for a motor vehicle, the hydraulic switching assembly comprising:
- a hydraulic pump that is adapted to feed a hydraulic medium from a sump via hydraulic lines;
- a magnetic valve assembly with a magnetically actuatable switching valve by which the hydraulic medium is adapted to be fed via the hydraulic lines to a switching element in order to hydraulically actuate the switching element between two switching positions;
- a pressure accumulator and a first check valve arranged in a feed line upstream of the switching valve that are adapted to provide a temporary supply of oil pressure to the switching element;
- and
- a throttle valve arranged in a bypass line upstream of the first check valve that allows a flushing of the hydraulic lines via a run-back line of the switching valve that leads to the sump.
