Abstract

The invention relates to a cap for a hydraulic fluid reservoir for a brake circuit of a vehicle. According to the invention, it has a filling aperture (24) intended to be closed by a valve member (38) through the action of a spring (36) mounted in the cap (10) in order to allow the reservoir to be filled on the assembly line without removing the cap. The valve member (38) is axially movable against the spring (36) which returns it in a closed position. The valve member (38) preferably has a seal.
