2. Presta valve - Wikipedia

   en.wikipedia.org/wiki/Presta_valve

   A valve extender (black) is fitted between valve stem (brass) and core (silver). Valve extenders can be used to lengthen shorter Presta valves to accommodate deeper and thicker rims, such as those on aerodynamic race wheels. There are two variants of valve extenders depending on whether the Presta core is removable. [6]

3. Learjet 25 - Wikipedia

   en.wikipedia.org/wiki/Learjet_25

   The Learjet 25 utilize wheel brakes as the primary method for reducing speed after landing. The brake system utilizes hydraulic pressure for power boost. The brake valves are controlled via the rudder pedal toe brakes through mechanical linkages. Two shuttle valves in the pressure lines prevent fluid feedback between the pilot's and copilot's ...

4. Actuator - Wikipedia

   en.wikipedia.org/wiki/Actuator

   Wheel and axle: Hoist, winch, rack and pinion, chain drive, belt drive, rigid chain and rigid belt actuators operate on the principle of the wheel and axle. By rotating a wheel/axle (e.g. drum, gear, pulley or shaft) a linear member (e.g. cable, rack, chain or belt) moves. By moving the linear member, the wheel/axle rotates. [19]

5. Relay valve - Wikipedia

   en.wikipedia.org/wiki/Relay_valve

   A relay valve is an air-operated valve typically used in air brake systems to remotely control the brakes at the rear of a heavy truck or semi-trailer in a tractor-trailer combination. Relay valves are necessary in heavy trucks in order to speed-up rear-brake application and release, since air takes longer to travel to the rear of the vehicle ...

6. Hydropneumatic suspension - Wikipedia

   en.wikipedia.org/wiki/Hydropneumatic_suspension

   It is the simplest damper and one of the most efficient. Ride height correction (self leveling) is achieved by height corrector valves connected to the anti-roll bar, front and rear. When the car is too low, the height corrector valve opens to allow more fluid into the suspension cylinder (e.g., the car is loaded).
