Electromagnetic on-off valve for triggering systems in a motor vehicle automatic gearbox parking brake needing accurate control because of their sensitivity has a cutout blade in a casing.

摘要

A distancing disk i.e. a magnetically non-conductive gap (6) fits on a casing (2) between one end of a cutout blade (3) and a stop (5). A 4/3-port directional control valve (1) serves to trigger a motor vehicle automatic gearbox parking brake and has two magnets to operate the cutout blade that fits in the casing and is aligned by a spring centering device (4).
