Record 1 2011-07-05

English

Subject field(s)
  • Closing Devices and Nozzles (Mechanical Components)
  • Refrigerating Machines and Appliances
  • Air Conditioning and Heating
DEF

A valve that is used to restrict the flow of a fluid and to produce a pressure drop.

OBS

throttle valve; throttling valve : terms officially approved by the Lexicon Project Committee(New Brunswick).

French

Domaine(s)
  • Obturateurs et buses (Composants mécaniques)
  • Machines frigorifiques
  • Conditionnement de l'air et chauffage
CONT

Robinet d'étranglement. Comme son nom l'indique, l'action d'étranglement intervient chaque fois qu'il s'agit de réduire ou de «freiner» dans une certaine mesure l'écoulement d'un fluide (gaz, vapeur, liquide) dans un conduit sans toutefois courir le danger d'une obturation totale.

OBS

robinet d'étranglement : terme uniformisé par le Comité du projet de lexiques (Nouveau-Brunswick).

Record 2 2008-01-18

English

Subject field(s)
  • Aircraft Systems
CONT

An emergency air brake control is mounted just outboard of the throttle lever, and is normally wired in the aft NORMAL position, a dump valve opens, relieving the hydraulic pressure. Air loads will then close the brakes. No emergency means of re-opening the brakes is provided.

OBS

air brake: Passive device extended from aircraft to increase drag. Most common form is hinged flap(s) or plate(s), mounted in locations where operation causes no significant deterioration in stability and control at any attainable airspeed.

Record 3 2004-08-24

English

Subject field(s)
  • Turboalternators and Turbogenerators
  • Helicopters (Military)
CONT

The amount of oil pressure directed to the actuator is controlled by two separate controllers : the density controller and the differential pressure controller. The density controller senses the temperature and pressure of the airflow in the engine intake. The differential pressure controller senses the difference between engine manifold pressure and the air pressure between the compressor and the throttle valve. When fully open, the waste gate valve routes the exhaust flow directly out the tailpipe, away from the turbine wheel. When fully closed, the waste gate valve routes the exhaust flow through the turbine wheel, thereby driving the turbine. During most stages of operation the controllers modulate the position of the valve to drive the turbine at the speed required to meet the engine power selection. The system is designed to work with no input from the pilot.

French

Domaine(s)
  • Turbo-alternateurs et turbogénérateurs
  • Hélicoptères (Militaire)
DEF

Dispositif qui règle automatiquement et en fonction de la densité du mélange explosif, la vanne de déviation (waste gate) du turbocompresseur.

CONT

La force de la pression d'huile dirigée vers l'actionneur est déterminée par deux régulateurs distincts : le régulateur de densité et le régulateur de pression différentielle. Le premier détecte la température et la pression de l'air dans l'entrée d'air moteur. Le second détecte la différence de pression entre celle du collecteur d'alimentation moteur et celle entre le compresseur et le papillon des gaz. Lorsqu'il est complètement ouvert, le limiteur achemine les gaz d'échappement directement dans le tuyau d'échappement, en contournant la turbine. Lorsqu'il est complètement fermé, le limiteur achemine les gaz d'échappement directement vers la turbine et la fait tourner. La plupart du temps, les régulateurs modulent la position du limiteur pour faire tourner la turbine à la vitesse correspondant au réglage de puissance du moteur. Le système est conçu pour fonctionner sans intervention humaine.

Record 4 2002-07-11

English

Subject field(s)
  • Climate-Control Equipment (Motor Vehicles)
CONT

Because there is no throttle valve or venturi in the airstream, there is no vacuum source that can be tapped on the diesel engine. Therefore, the diesel engine requires a vacuum pump to provide the vacuum to operate various devices on the car, such as power brakes and air-conditioner vacuum doors.

Record 8 1990-01-23

English

Subject field(s)
  • Heating
DEF

A system which regulates steam flow into the main throttle valve under automatic thermostatic control and maintains a fixed vacuum differential between supply and return by means of a differential controller and a vacuum pump.

CONT

Subatmospheric systems are similar to vacuum systems, but in contrast provide a means of partial vacuum control on both the supply and return piping so that the steam temperature can be regulated to vary the heat emission from the heat exchanger in direct proportion to the heat loss from the structure.

French

Domaine(s)
  • Chauffage
OBS

Chauffage à pression sous-atmosphérique. C'est un chauffage à vapeur à basse pression dans lequel les tuyauteries n'ont aucune communication avec l'atmosphère.

OBS

Dans les chauffages à vapeur, le fluide véhiculaire utilisé est la vapeur d'eau. La vapeur produite dans les chaudières est conduite jusqu'aux corps de chauffe par un réseau de canalisations, s'y condense en cédant sa chaleur latente de vaporisation et retourne sous forme d'eau aux chaudières, à partir desquelles le cycle recommence. On distingue: -suivant la pression : (...) les chauffages à vapeur à pression sous-atmosphérique (...)
