PISTON BODY [9 records]

English

Subject field(s)
  • Mechanical Components
CONT

Piston accumulators consist of a cylindrical body, sealed by a gas cap and charging valve at the gas end, and a hydraulic cap at the hydraulic end. A lightweight piston separates the gas side of the accumulator from the hydraulic side. This design offers high efficiency and flexibility in most applications due to a very wide range of sizes.

  • Braking Systems (Motor Vehicles and Bicycles)
CONT

In the compression mode of the shock absorber, fluid is forced into the remote reservoir in direct proportion to the area of the shaft entering the shock body. … As fluid is forced through the … drum …, it is metered through one of the preassigned orifices in the drum; it then enters the reservoir body, moving the floating piston. The floating piston is designed to separate the fluid and nitrogen, eliminating any chance of aeration.

Subject field(s)
  • Aeronautical Engineering and Maintenance
CONT

The rudder actuator is a tandem actuator, having two internal piston areas for each hydraulic source(A & B). The actuator is capable of positioning the rudder panel with either one or both main hydraulic sources available, though with one source inoperative a reduced rudder panel deflection would result due to blowdown at higher airspeeds. Flow of hydraulic fluid to the rudder actuator is controlled by the dual servo-valve. This is a complex dual concentric cylinder with an outer and inner slide. During normal rudder pedal inputs sufficient rudder panel deflection is catered for by the primary(inner) valve alone. However, should a larger panel deflection be required or a higher rate rudder input be commanded, the secondary(outer) sleeve moves in addition to port extra fluid to the actuator. Movement of the outer sleeve is typically no more than 1 mm. Position of both sleeves of the servo valve is controlled by a complex mechanism of bell cranks, input rod and summing lever, the geometry of which is such as to provide movement of the sleeves in relation to the body of the valve.

Subject field(s)
  • Landing Gear (Aeroindustry)
OBS

The nose-gear strut is a steerable, dual-wheel, fully retractable oleo strut. It supports the forward portion of the airplane, absorbs landing shock, and steers the airplane through ground maneuvers. The strut is supported by the side braces and crossarm, which are part of the strut casting, and by the drag links. The major components of the strut are the cylinder body, the steering cylinder, and the piston.
