An oil drain combination for a brake contains: a wrench and a draining assembly. The wrench is a ratchet wrench. The draining assembly is connected in the wrench and includes a coupling shaft, a fitting member, a first joining tube, and a fixing member. The fitting member is rotatably accommodated in a drive head of the wrench. An axial line of the fixing member extends from the first segment of the fixing member to a second segment of the fixing member and insects with a central line of the coupling shaft perpendicularly. The first joining tube has an accommodation orifice and an axial orifice. The coupling shaft has a blind orifice and multiple radial orifices. The fixing member has a first connection hole communicating with a second connection hole.

A fluid container for supplying a consuming device with a working fluid, including at least one connector piece having a shut-off valve arranged therein for preventing undesired escaping of the working fluid from the fluid container. In order to increase safety against undesired emptying of the fluid container, it is provided that the valve closure body, in the closed state of the shut-off valve, is accommodated in the fluid container completely inside a contour formed by an outer edge of the connector piece, and provision is made, for support against the valve closure body, of a support, which, upon insertion of the connector piece into the receiving seat, engages at least regionally into the connecting duct and in this way displaces the valve closure body in the connecting duct.

A fluid container for a hydraulic unit comprises a container housing which has at least one connection part, which can be shut off by means of a shut-off device arranged in the fluid container. The container housing has at least one internal chamber and a channel for connecting the internal chamber to the hydraulic unit. The connection part and the shut-off device are combined in a separate module, which is connected to the container housing.

A valve assembly is provided. The valve assembly includes a valve body defining a bore. The valve assembly further includes a pull rod disposed in the bore and defining a bolt cavity. The pull rod is moveable between a first pull rod position and a second pull rod position. The valve assembly further includes a bolt disposed in the bolt cavity and moveable with respect to the pull rod between a first bolt position and a second bolt position. The valve assembly further includes a spool disposed in the bore. The spool is operatively coupled to the pull rod to move between an energized position and a neutral position.
