Levelling valve
| Глоссарий в железнодорожной технике |
A levelling valve is used to determine the variations in vehicle weight caused by loading and unloading. it is a pneumatic device mounted on the vehicle underframe and connected to the bogie, which measures the body`s vertical displacement relative to the bogie caused by weight changes. the valve sends a pneumatic signal to the traction and braking systems to adjust their rates according to the vehicle weight. it is used in conjunction with air suspension to cause the vehicle height to remain constant regardless of load. the levelling valve is a fairly recent development (in railway terms) over the last 15 years and is used as part of modern traction and braking control systems. some trains can be heard expelling air from their suspension system levelling valves as passengers alight and the system adjusts.

Valve, английский
- Vanne /soupape
- A device that regulates the flow of water.
- A device which controls fluid flow direction, pressure, or flow rate.
- Клапан
- Válvula
- A device which regulates or closes off the flow of a fluid.
- An automatic which permits liquid to flow in only one direction. also
- A flap which opens and closes to allow liquid to pass in one direction only, e.g. in the heart, blood vessels or lymphatic vessels
- Вентиль
- A tap-like device for controlling the passage of gas or fluid through a pipe.
- Any contrivance inserted in a pipe or tube containing a lid, cover, ball, or slide that can be opened or closed to control the flow or supply of liquids, gases, or other shifting material through a passage.
- Клапан; вентиль, задвижка, шибер
- Гидроагрегат распределитель, клапан и т.п.

Underframe, английский
Railway vehicle base which forms the support for the body structure or is an integral part of a body shell.
Displacement, английский
- Перемещение
- Водоизмещение
- The weight of water displaced by the immersed volume of a ship`s hull, exactly equivalent to the weight of the whole ship.
- The weight, in tons of 2,240 pounds, of the vessel and its contents. calculated by dividing the volume of water displaced in cubic feet by 35, the average density of sea water.
- Перемещение, сдвиг, весовое водоизмещение,
- The fact of being moved out of the usual position fracture of the radius together with displacement of the wrist
- Водоизмещение судна
- Водоизмещение; водоизмещающее плавание
- The centre of gravity of the displacement relates to the part of the ship under water, considered as homogeneous. the weight of water which a vessel displaces when floating is the same as the weight of the ship. (see centre of cavity.)
- Weight of a vessel expressed as either the number of long tons, or the cubic feet of water, displaced by the hull (1 ton = 35 cu.ft of seawater or 35.9 cu.ft of fresh).
- The volume of liquid delivered by a single stroke of a pump piston.
- Sometimes used as a synonym for offset deflec tion, deviation, dislocation, throw.
- The capacity of an air compressor, usually ex pressed in cubic feet of air per minute (c.f.m.).
- The weight of water dislocated by the hull of a vessel.
- The weight of a boat measured according to the weight of water it displaces. a boat displaces an amount of water equal to the weight of the boat, so the boat’s displacement and weight are identical.
- Изменение линейного или углового положения* перемещение, отклонение органа управления
- The product of stroke and of cylinder bore and number of cylinders of an engine, representing the theoretical volume of (incompressible) working fluid that can be drawn into an engine with each cycle. see also capacity and swept volume. 45
- Displacement is where you change your nearest relative. the process of changing the nearest relative is often known as ‘displacement proceedings’. your nearest relative can be displaced if you or the local authority have concerns about the way that they are behaving. see our pages on the nearest relative for more information.
Conjunction, английский
- N союз coordinating ~ сочинительный союз (ант. subordinating ~) subordinating ~ подчинительный союз (ант. coordinating ~)

Suspension, английский
- El acto de parar un proceso judicial por orden del tribunal
- Подвеска
- Приостановление
- A liquid with solid particles in it
- To relieve an officer of his duties for up to ten days as a non-judicial punishment. a longer suspension may be allowed if court-martial is pending.
- Временная отставка, временное отстранение от должности до решения вопроса об увольнении временное (не более чем на 10 дней) отстранение студента или школьника от занятий в наказание за нарушение правил внутреннего распорядка
- Means whereby vehicle body is supported on its undercarriage, comprising springs, dampers and locadng hnkages.
- The combination of tires, wheels, hubs, spindles, control arms, springs, struts, shock absorbers and related parts that support the chassis and body as the vehicle moves down the road.
- Bath.
- This is when an employee is sent home from work, usually while receiving full pay. employers are entitled to suspend
- Suspension is the practice of temporarily banning an employee from a job or from the entire workplace for breaking specific company rules.
- An employee is sent home for a period of time, usually without pay, as a disciplinary measure.
- Often relating to springs, where support is given in furniture.

Static load test bed, английский
A locomotive test facility provided to see if the performance requirements of a design are met. called a "load tank" in the us.
Short circuiting device, английский
A hand tool for preventing traction current from being switched on to a dc electrified line. applies only to third rail systems. generally mounted on trains and stations for use in emergency, they are not supposed to be used for discharging current, only for preventing recharge. a shorting tool is also used to earth overhead line by connecting the contact wire to the track rail in the section where it has been isolated.
