Abstract
A liquid reservoir, particularly for use in an hydraulic system. The reservoir includes a container and a cover cap, and it is intended for containing an hydraulic pressure medium. A pressure equalization component is provided within the container for compensating for pressure differences between the interior of the container and the surrounding atmosphere, and a level compensation component is provided for compensating for changes in the volume of the pressure medium. The pressure equalization component is functionally separate from the level compensation component.
