Tauchdichtes ABS/ASR-Pumpenaggregat mit Rückschlagventil

摘要

The invention relates to a pumping set for a controlled braking system (ABS/drive slip control). In such an assembly, brake fluid forced by the piston accumulates in the spaced around the eccentric (4) and, when in sufficient quantity, is pressurised by the moving pistons. The use of a simple outlet channel in the environment raises problems, at least in immersion-proof vehicles, through the penetration of moisture and dirt. The invention helps here by the introduction of a check valve (15) fitted in the outlet channel which is so designed that it opens under the weight of the accumulated brake fluid and reliably prevents the ingress of dirt and moisture in the opposite direction.
