AIR TRAPS [11 records]

Record 1 2025-02-13

English

Subject field(s)
  • Ship and Boat Parts
  • Hydroplanes and Hydrofoils
CONT

The basic mechanism of a hovercraft is very simple : there's an engine(diesel or gasoline) that powers both a large central fan, pointing downward, and one or more other fans pointing backward. The central fan creates the lift that holds the craft above the waves; the other fans propel the craft backward, forward, or to the side. A rubber skirt(with or without fingers) traps a cushion of air under the craft.

French

Domaine(s)
  • Parties des bateaux
  • Hydroglisseurs et hydroptères
CONT

Fabriquée de néoprène renforcé, un caoutchouc synthétique thermoplastique, la jupe est constituée d'un boudin perforé sous lequel se retrouvent des segments repliés sur eux-mêmes en forme de cônes (finger).

Record 2 2019-11-28

English

Subject field(s)
  • Transformation of Momentum (Mechanical Components)
  • Engines (Motor Vehicles)
CONT

When a piston in an engine is pushed up into its cylinder, the upward movement traps the mixture of air and fuel above it and compresses it to one-eighth or one-ninth of its original volume. This puts the molecules closer together, so they hit the piston head far more often. Thus, the pressure goes up.

OBS

piston crown; piston head: designations officially approved by the Lexicon Project Committee (New Brunswick).

French

Domaine(s)
  • Transformations de mouvements (Composants mécaniques)
  • Moteur (Véhicules automobiles)
OBS

Moteurs à explosion.

OBS

tête de piston : désignation uniformisée par le Comité du projet de lexiques (Nouveau-Brunswick).

Spanish

Campo(s) temático(s)
  • Transformación de la cantidad de movimiento (Componentes mecánicos)
  • Motores (Vehículos automotores)
CONT

La forma del émbolo y la de aplicar la fuerza del gas a la biela a través del perno del émbolo dependen además mucho de la forma de la cámara de combustión y por lo tanto de la forma de la cabeza del émbolo, y del sistema de combustión empleado y sus presiones máximas de combustión.

Record 3 2019-09-09

English

Subject field(s)
  • Thread Spinning (Textiles)
  • Wool Industry
DEF

The natural waviness of the wool fiber[, which] varies with the diameter of the fiber.

CONT

The crimp in wool fibres makes it soft and springy to touch. It also adds bulk and traps a large volume of air between the fibres, giving it good insulation properties.

Key term(s)
  • fiber crimp

Record 4 2016-05-09

English

Subject field(s)
  • Closing Devices and Nozzles (Mechanical Components)
  • Taps and Plumbing Accessories
  • Heating
DEF

[A] trap with an inlet channeled to the bottom of the trap body so the condensate enters underneath the inverted bucket[, and in which the] valve opens when the trap fills with condensate and discharges the condensate into the return line.

CONT

The discharge from the inverted bucket trap is intermittent and requires a differential pressure between the inlet and discharge of the trap to lift the condensate from the bottom of the trap to the discharge connection. Bucket traps are used for draining condensate and air from blast coils, unit heaters and steam heating coils. Inverted bucket traps are well suited for draining condensate from steam lines or equipment where an abnormal amount of air is to be discharged and where dirt may drain into the trap.

French

Domaine(s)
  • Obturateurs et buses (Composants mécaniques)
  • Robinetterie et accessoires
  • Chauffage
DEF

Purgeur de vapeur muni d'un flotteur ouvert en forme de cuve inversée ou de cloche, solidaire d'un clapet assurant l'ouverture et la fermeture de l'orifice d'évacuation des condensats.

CONT

Le purgeur à flotteur inversé […] fonctionne de façon identique [au purgeur à flotteur ouvert en seau]. Lorsque la vapeur arrive, elle s'accumule sous la cloche[,] qui se vide d'eau et s'élève, fermant le clapet de retenue, tandis que l'afflux de condensats fait redescendre le flotteur par son poids, ce qui libère le clapet. Il s'agit donc d'un fonctionnement par chasses successives. C'est un système assez délicat et sensible au gel.

Record 5 2016-05-04

English

Subject field(s)
  • Closing Devices and Nozzles (Mechanical Components)
  • Taps and Plumbing Accessories
  • Heating
DEF

A bucket that is usually hinged, so [that] water enters in sufficient quantity to fill the bucket and sinks it, [thus opening] a valve [and allowing] water [to flow] into the return line through a tube that extends almost to the bottom of the bucket.

CONT

Upright Bucket Trap. The discharge of condensate from this trap is intermittent. A differential pressure of at least 1 psi [pound per square inch] between the inlet and the outlet of the trap is normally required to lift the condensate from the bucket to the discharge connection. Upright bucket traps are commonly used to drain condensate and air from the blast coils, steam mains, unit heaters and other equipment. This trap is well suited for systems that have pulsating pressure.

French

Domaine(s)
  • Obturateurs et buses (Composants mécaniques)
  • Robinetterie et accessoires
  • Chauffage
DEF

Purgeur à flotteur ouvert vers le haut, en cloche renversée (type seau) solidaire d'un clapet assurant l'ouverture et la fermeture de l'orifice d'évacuation des condensats.

OBS

[Dans le cas des purgeurs à flotteur ouvert en seau], le corps du purgeur se remplit d'abord d'eau jusqu'à ce qu'il déborde dans le flotteur et l'amène à s'abaisser. Le clapet de retenue s'ouvre alors et c'est la pression de vapeur qui évacue l'eau condensée.

Record 6 2016-05-04

English

Subject field(s)
  • Taps and Plumbing Accessories
  • Heating
CONT

Thermostatic traps are the most common of all types used in two-pipe steam heating systems.... They are designed to open in response to pressure and temperature to discharge air and condensate and to close against the passage of steam.... Balanced pressure-type thermostatic traps are those which have been described. They employ thermal elements made from metal bellows, a series of diaphragms, or special cells made from diaphragms. There are some types that employ special shapes of bimetal for the thermal elements.

Key term(s)
  • balanced pressure-type thermostatic trap

French

Domaine(s)
  • Robinetterie et accessoires
  • Chauffage
DEF

Purgeur de vapeur dont les mouvements d'ouverture et de fermeture sont commandés par des déséquilibres crées entre la pression des condensats dans le purgeur et la tension de vapeur du liquide volatil contenu dans un élément déformable.

CONT

Les vêtements qui sont en contact direct avec la peau s'imprégneront de sueur et leur facteur d'isolement chutera alors de façon considérable, ce qui augmente le risque de lésions dues au froid.

CONT

Le gant thermique léger/mortier est un gant ajusté comportant un tissu trois épaisseurs [trois couches contrecollées] avec [une] face en nylon et [une] couche de molleton velours près de la peau.

Record 8 2012-01-30

English

Subject field(s)
  • Respiratory System
DEF

Pneumothorax in which a valve effect in the ruptured bleb or alveolar tissue permits air to enter the pneumothorax cavity during inspiration, but traps it during expiration, so that pressure builds up, displaces the mediastinum to the opposite side, and encroaches upon and distorts blood vessels.

French

Domaine(s)
  • Appareil respiratoire
DEF

Pneumothorax spontané dans lequel la communication pleuro-pulmonaire fait office de clapet; la pression de l'air intrapleural augmente, provoquant une compression du poumon.

To furnish(a drain, etc.) with a trap or traps, to prevent the ascent of foul air or gas.
