POPPET [16 records]

Record 1 2022-04-13

English

Subject field(s)
  • Mechanical Components
CONT

Bladder accumulators feature a non-pleated, flexible rubber bladder housed within a steel shell. The open end of the bladder is attached to the pre-charging valve at the gas end of the shell. A poppet valve prevents the bladder from extruding through the hydraulic port.

French

Domaine(s)
  • Composants mécaniques
CONT

Les accumulateurs à vessie sont basés sur le même principe que les accumulateurs à membrane en ce sens que l'élément séparateur entre le gaz et l'huile est une vessie souple en élastomère, intimement solidarisée à la valve de gonflage. Un clapet (ou soupape) obstrue l'orifice d'arrivée d'huile pour éviter l'extrusion de la membrane.

Record 2 2021-07-23

English

Subject field(s)
  • Mechanical Components
  • Diesel Motors
CONT

The side bypass thermostat functions similarly to the poppet type. It has a circular sleeve below the valve that moves with the valve as it opens. This partially blocks the bypass circuit and, in doing so, directs most of the coolant flow to the radiator.

Key term(s)
  • side by-pass thermostat

French

Domaine(s)
  • Composants mécaniques
  • Moteurs diesel
CONT

Le thermostat à dérivation latérale fonctionne de façon similaire à celui de type à soupape simple. Il possède un manchon circulaire en dessous de la soupape qui se déplace avec la soupape durant lʼouverture de celle-ci : ce mouvement bloque partiellement le circuit de dérivation et dirige la circulation en grande partie vers le radiateur.

Record 3 2012-02-15

English

Subject field(s)
  • Aircraft Systems
CONT

Flow control valves. In this valve assembly, individual poppet valves are used to open and close the ports to change the direction of fluid flow. The valves are operated by cams on a cam rod.... Some poppet valve assemblies are arranged with valves in a radial position, and they are opened and closed by means of a rotary cam unit. The results are the same in any case. Poppet valves are also manufactured with electric controls, and the individual valves are opened and closed by means of solenoids.

PHR

Spring-loaded poppet valve.

Record 4 2011-10-05

English

Subject field(s)
  • Transformation of Momentum (Mechanical Components)
OBS

the [actuating] shaft, through gearing, rotates two poppet assemblies to shut off the pressure in each hydraulic system, at the same time interconnecting both sides of each piston section of the actuating cylinder when the booster assembly is shifted to boost off operation to prevent hydraulic lock of each piston section.

English

Subject field(s)
  • Taps and Plumbing Accessories
  • Aircraft Systems
DEF

A valve which controls pressure, volume, or flow direction in a fluid transmission system.

CONT

Pneumatic systems are often compared to hydraulic systems, but such comparisons can only hold true in general terms.... Control valves are... a necessary part of a typical pneumatic system.... The control valve consists of a lever with two lobes. [In the off position], a spring holds the left poppet closed so that compressed air entering the pressure port cannot flow to the brakes. [In the on position], one lobe of the lever holds the left poppet open and a spring closes the right poppet. Compressed air now flows around the opened left poppet, through a drilled passage, and into a chamber below the right poppet. Since the right poppet is closed, the high-pressure air flows out of the brake port and into the brake line to apply the brakes. To release the brakes, the control valve is returned to the off position.
