Record 1 2016-11-07

English

Subject field(s)
  • Braking Devices (Mechanical Components)
  • Braking Systems (Motor Vehicles and Bicycles)
DEF

A hydraulic brake actuator mounted inside the brake drum and containing one piston, or two opposing pistons, cup seals, and a spring to hold the cup seals against the piston face.

CONT

As the pedal is depressed, it moves a piston within the master cylinder, forcing hydraulic fluid throughout the system and into cylinders at each wheel. Here, it causes the wheel cylinder pistons to move which, in turn, forces the brake shoes against the brake drums to retard their movement.

OBS

wheel cylinder: term officially approved by the Lexicon Project Committee (New Brunswick).

French

Domaine(s)
  • Freins (Composants mécaniques)
  • Freins (Véhicules automobiles et bicyclettes)
DEF

Récepteur de freinage hydraulique placé à l'intérieur du tambour de frein de roue et comportant un piston, ou deux pistons opposés, des coupelles d'étanchéité et un ressort maintenant les coupelles appliquées sur la face du piston.

CONT

Les cylindres récepteurs [...] peuvent être de différents modèles. Le plus souvent ils sont du type «intérieur» aux tambours et fixés d'une façon rigide sur le plateau ou flasque de frein.

OBS

cylindre récepteur; cylindre de roue : termes uniformisés par le Comité du projet de lexiques (Nouveau-Brunswick).

Spanish

Campo(s) temático(s)
  • Frenos (Componentes mecánicos)
  • Frenos (Vehículos automotores y bicicletas)
DEF

Válvula de freno hidráulico ubicada en la cara interna del tambor que comporta uno o dos pistones contrapuestos, arandelas de empaque y un resorte que mantiene la empaquetadura contra el cuerpo del pistón.

Record 2 2006-11-16

English

Subject field(s)
  • Guns (Land Forces)
  • Armour
CONT

When the piston extension reaches the end of its rearward movement, it slams against the buffer's face, or "bush", forcing it to recoil slightly. The bush transfers its movement to a braking cone which penetrates the braking ring, causing it to open. As it expands, the braking ring contacts the interior wall of the buffer cylinder, exerting a braking action...

Record 3 2001-01-08

English

Subject field(s)
  • Plumbing Tools and Equipment
CONT

Pyrotechnic Tubing Connector. The Pyrotool would employ a pyrotechnic charge to compress the fittings. It would include a piston and cylinder containing the fittings and would be preattached to the end of a tube section. The user would insert the mating tube in the tool and fitting and would detonate the charge by mechanical or electrical means. The burning charge would generate pressure on the piston face, driving the piston toward the mating tube so that it compresses the fitting, thereby joining the tube ends... Once used, the tool would remain on the joined tubes.

French

Domaine(s)
  • Appareillage et outils de plomberie

English

Subject field(s)
  • Joining Elements (Mechanical Components)
  • Bearings and Bearing Systems (Mechanical Components)
OBS

SKF hydraulic nuts simplify mounting and dismounting, particularly of larger bearings with tapered bores. They consist of an internally threaded steel ring with a groove in one face into which is fitted an annular piston.

French

Domaine(s)
  • Éléments d'assemblage (Composants mécaniques)
  • Paliers, coussinets et roulements (Composants mécaniques)
OBS

Les écrous hydrauliques SKF, fabriqués en acier de haute qualité, facilitent le montage et le démontage des roulements à alésage conique de grandes dimensions. Ils comprennent un corps muni, d'un côté, d'une gorge annulaire dans laquelle un piston se déplace axialement lorsqu'on introduit de l'huile sous pression.
