The present disclosure in some embodiments provides an oil reservoir assembly for a vehicle, the assembly comprising: a first oil reservoir formed with an outlet; a second oil reservoir spaced apart from the first oil reservoir in a lateral direction and in front of the vehicle, in fluid communication with a master cylinder, and having an inlet; a connecting member connecting the outlet and the inlet to convey a working fluid from the first oil reservoir to the second oil reservoir and a first rib located inside the second oil reservoir, extending from an upper surface of the second oil reservoir and parallel to a longitudinal direction of the vehicle, and extending in a first direction of the inlet.

As an example, a reservoir tank according to an embodiment includes: an upper case; a lower case coupled to the upper case; a partition wall extending from the upper case toward the lower case and separating, in a horizontal direction, first and second rooms which are included in a space inside the upper case and the lower case; and a partition member having a first wall covering the first room from below, and a second wall protruding upward from the first wall and being in contact with the partition wall. The partition wall includes a first slit opening to a lower edge of the partition wall and establishing communication between the first and second rooms, and at least an edge of the first slit and the second wall forming a first hole which establishes communication between the first and second rooms and which is positioned above the first wall.

A valve assembly for a pneumatic system of a vehicle, in particular a commercial vehicle, including: an outlet valve assembly for venting the pneumatic system, a control device for operating the valve assembly in order to admit and release air to and from a pneumatic actuator, wherein the control device is configured to output, to the outlet valve assembly, a switching signal for switching the outlet valve assembly, and, via the switching signal, the outlet valve assembly can be switched to a noise-reducing first venting mode or a quick-venting second venting mode.

Apparatus and associated methods relate to a vehicle having independent fluid reservoirs for a fluid-activated brake system and at least one auxiliary fluid consumer. In an illustrative example, a first reservoir may be mounted above a chassis and outboard of a vehicle such that longitudinal axes of the reservoir and the vehicle are substantially aligned. The first reservoir may, for example, be fluidly coupled to a fluidly activated brake configured to brake at least one wheel on at least one axle of the vehicle and fluidly coupled to the first reservoir. At least one second reservoir may be fluidly coupled to at least one auxiliary fluid consumer of the vehicle such that the first reservoir is fluidly independent from the at least one second reservoir and the at least one auxiliary fluid consumer. Various embodiments may advantageously provide stable air supply for critical braking functions of the vehicle.

A trailer braking system includes a supply line, a spring brake that moves from an apply position to a release position, a spring brake control valve which controls the flow of fluid to the spring brake, an immobiliser having a brake release and immobilise positions which control the flow of fluid to the spring brake control valve, an auxiliary control valve having a system enabled configuration where the immobiliser is operable to move both to the brake release position in which the immobiliser permits fluid to the spring brake control valve and the spring brake control valve is operable to cause the flow of pressurised fluid into the spring brake, and an immobilise position where fluid is not permitted to the spring brake control valve, and in the system disabled configuration, the immobiliser is placed in the immobilise position.

A brake fluid reservoir for a vehicle brake system includes a housing defining a fluid chamber for brake fluid. A funnel is mounted to the housing in the fluid chamber and defines first and second chamber portions of the fluid chamber. The funnel has an inlet opening via which brake fluid flows into the funnel from the first chamber portion and an outlet opening via which the brake fluid flows into the second chamber portion from the funnel. A valve mechanism operatively cooperates with the outlet opening to at least partially prevent brake fluid from flowing through the outlet opening from the second chamber portion toward the first chamber portion.

A hydraulic disc braking system is disclosed. The system has a manually operated control device for a cyclist to issue a braking command. The system has a master cylinder assembly having a membrane dividing the hydraulic fluid tank into a variable volume filled chamber and a complementarily variable volume empty chamber. A membrane detector senses the presence of the membrane relative to a predetermined position in the tank and/or a meter measures the distance of the membrane from the ceiling of tank.
