Patent ID: 7191912

Claim:
Brake fluid reservoir for a vehicle hydraulic brake system, having a filler neck, a lid which closes the filler neck, and a device for pressure compensation between the reservoir interior and the ambient atmosphere, wherein in the lid a first brake fluid forced-flow channel is formed, which has an inlet at the inside of the lid and an outlet towards the outside of the lid and which between the inlet and the outlet extends along a curved path, which in relation to a plan view of the lid runs through at least two quadrants, wherein the outlet is displaced circumferentially from the inlet such that all fluid flowing between the inlet and the outlet is forced through the at least two quadrants, and wherein the outlet is connected to an outlet line, which leads upwards to the outside of the lid; wherein a second forced-flow channel having an inlet and an outlet is formed in the lid above the first forced-flow channel and extends between the inlet and the outlet along a curved path, which in relation to a plan view of the lid runs through at least two quadrants, wherein the inlet of the second forced-flow channel is connected to the outlet of the first forced-flow channel and the outlet of the second forced-flow channel is connected to the ambient atmosphere.
