A cross-section of a proportioning safety valve. A proportioning valve is a valve that relies on the laws of fluid pressure to distribute input forces to one or more output lines. Proportioning valves are frequently used in cars and other road vehicles to reduce the brake fluid pressure to the rear brakes. Due to weight distribution during ...
The train brakes are released by admitting reduced and regulated main reservoir air pressure to the brake pipe through the engineer's automatic brake valve. In America, a fully charged brake pipe typically operates at 90 psi (6.2 bar; 620 kPa) for freight trains and 110 psi (7.6 bar; 760 kPa) for passenger trains. [7]
Incorrect brake pad linings; Greasy brake pad linings, faulty proportioning valve, misadjusted master cylinder pushrod Noisy braking (grinding or screeching sounds when braking) Extremely worn brake pads, brake pad(s) not fitted correctly, faulty or missing brake pad shim, brake pad wear indicator Vibration under braking
The driver's brake pedal simply controls a valve to bleed pressure into the brake units at the wheels, rather than actually creating the pressure in a master cylinder by depressing a piston. This form of brake is analogous to an air brake system but with hydraulic fluid as the working medium rather than air.
There is a valve in the brake line of each brake controlled by the ABS. On some systems, the valve has three positions: In position one, the valve is open; pressure from the master cylinder is passed right through to the brake. In position two, the valve blocks the line, isolating that brake from the master cylinder.
When the brake pipe and car components are charged with air, the brakes release. When the engineer needs to make a brake application, control valves in the locomotive reduce the brake pipe pressure. As the brake pipe pressure is reduced, the service portions on each car divert air from their reservoirs to their brake cylinders.
Westinghouse Air Brake Company's Rotair Valve [18] The first form of the air brake consisted of an air pump, a main reservoir (pressure vessel), and an engineer's valve on the locomotive, and of a train pipe and brake cylinder on each car. One problem with this first form of the air brake was that braking was applied to the first cars in a ...
The driver's brake valve is a complicated valve system for controlling the compressed air brake of a railway vehicle. [1] Depending on its setting, it controls whether the brake pipes of a compressed air brake are evacuated and thus whether braking is applied or maintained; or if the brake pipes are connected to a compressed air reservoir, it ...
