Abstract
A brake fluid reservoir (10) for a vehicle hydraulic brake system has a filler neck (16), a lid (18) which closes the filler neck, and a device for pressure compensation between the reservoir interior and the ambient atmosphere. In order, when the brake fluid reservoir (10) is in a steeply inclined position, to prevent an escape of brake fluid, in the lid (18) a first brake fluid forced-flow channel (32) is formed, which has an inlet (34) at the inside of the lid and an outlet (36) towards the outside of the lid. The forced-flow channel (32) extends between the inlet (34) and the outlet (36) along a curved path, which in relation to a plan view of the lid (18) runs through at least two quadrants.
