A work vehicle according to the present invention includes an engine installed in a traveling machine body supported by traveling units, and a transmission case incorporating a hydraulic continuously variable transmission. The transmission case incorporates a forward/backward traveling switching mechanism. The work vehicle includes forward traveling valves for forward traveling hydraulic clutches, a backward traveling valve for a backward traveling hydraulic clutch, and a master valve configured to control hydraulic oil supplying to the forward traveling valves and the backward traveling valve. A part of a hydraulic circuit is formed on a front lid member of the transmission case. The forward traveling valves, the backward traveling valve, and the master valve are attached on a front surface side of the front lid member.

A container unit for brake fluid in a vehicle hydraulic brake system and connectable to a hydraulic component of the brake system, and includes: a storage chamber for brake fluid, the storage chamber having a flow channel between the storage chamber and the hydraulic component, the storage chamber and flow channel define an inner space of the container unit; a displaceable valve unit regulates flow of brake fluid in and out of the storage chamber through the flow channel, the valve unit in an open position is displaced to allow brake fluid to flow when the container unit is connected to the hydraulic component, and the valve unit in a closed position is displaced to prevent outflow of brake fluid when the container unit is disconnected from the hydraulic component. The valve unit in the open and closed positions is fully enclosed within the inner space of the container unit.

A hydraulic oil resupply device (40) is provided between first accumulators (15F, 15R) in a manual braking operation circuit (11) and a second accumulator (25) in an automatic brake circuit (24). The hydraulic oil resupply device (40) resupplies hydraulic oil accumulated in the second accumulator (25) to the first accumulators (15F, 15R) at the operating of a manual braking operation by an operator. This configuration can suppress a rising speed of a brake pressure at the manual operation braking from being slow. Accordingly, in a vehicular brake system, it is possible to enhance a braking capability by the manual braking operation and improve the reliability.

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 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.
