A braking circuit including at least an auxiliary right valve (200) and an auxiliary left valve (300) suitable to allow braking on both sides, right and left of a vehicle, when this is required, but allowing to apply a pressure braking only on one of the two sides, right or left, when this is required to provide a steering function, characterized in that the circuit further comprises a master valve (400) having two positions: a first position when the vehicle has a velocity under a threshold wherein separate and selective right or left braking is authorized and a second position when the vehicle has a velocity above said threshold wherein said master valve (400) connects both a right braking line (204, 1205) and a left braking line (304, 1305) to an output braking line (110) so that if a braking is requested both right braking line (204, 1204) and left braking line (304, 1305) are under pressure and selective right or left braking is forbidden.

A hydraulic block for a hydraulic power unit of a hydraulic vehicle brake system includes a main brake cylinder bore and an intake that are integrated to form a pedal travel simulator.

A brake system for a vehicle having at least two axles. The system includes a first and second axle units which can be or are installed on a first and second axle, respectively, of the vehicle. The second axle unit is hydraulically separate from the first axle unit. The first axle unit is a dual-circuit first axle unit. The first and second brake circuits are each configured such that, by operation of a respective motorized brake pressure buildup device, brake fluid can be transferred from a connected brake fluid reservoir into a respective wheel brake cylinder, and, via a respective outlet valve, brake fluid can be discharged from the respective wheel brake cylinder into the connected brake fluid reservoir.

A combined dirt collector and cutout cock (CDC & COC) device for a rail car control to prevent unintentional re-pressurization of the control valve and rail car braking system. The device has an inlet configured for interconnection to an air supply, an outlet configured for interconnection to a control valve of a rail car, a valve moveable between a first position where an inlet is connected to an outlet and a second position where the inlet is isolated from the outlet, and a control valve vent positioned downstream of the valve and configured to open in response to the valve being moved into the second position. The valve may include a ball having a first passageway for selectively connecting and disconnecting the inlet from the outlet and a second passageway formed therethrough that is positioned to interconnect the outlet with the vent when the valve is in the second position.

A pneumatic valve (1) includes a housing (6), a supply connection (8), a working connection (10) for providing working pressure (pB), an exhaust portion (12) for discharging pressurized air, an attachment portion (74), a valve member (24) and a venting guide (4). The venting guide (4) has a venting channel (108) and complementary connection elements (76) engaging the attachment portion (74), a spout (78), and a support projection (100). The support projection (100) is positioned adjacent to a contact region (102) of the housing (6) and configured to abut the contact region (102) to block tilting of the venting guide (4) relative to the housing (6). A vehicle (300) includes a brake system (200) having the pneumatic valve (1).

A remote brake fluid reservoir, a remote brake fluid reservoir connected to a brake cylinder, vehicle assemblies with the same, parts facilitating the vehicle assemblies, and methods of manufacturing, integrating, and using the same are described herein. The remote brake fluid reservoir and the brake cylinder may be separated by a bulkhead on a body of a vehicle. Additionally, a brake fluid path can extend from the brake fluid reservoir to the brake cylinder through an opening in the bulkhead, the opening in the bulkhead having a seal. The remote brake fluid reservoir may be mounted within a front compartment of the vehicle. A center line of the brake fluid reservoir can be aligned with a center line of the vehicle. In addition, the brake cylinder may be located in a different compartment of the vehicle, such as a cabin of the vehicle, for example.
