depends on if it is an automatic and how many gears there are sometimes one valve controls two gears
Yes. Electrovalves are electronically controlled valves that allow or impede flow of materials. The companies Berg and Eclipse use these for liquor controls in bars.
Usually with electronically controlled valves or any other device that has movement limits, there will be either a slotted ribbon, or 2 sensors and a stepper motor where the device can auto calibrate by moving until both sensors are hit, then it can calibrate it's self and move to a predetermined home position. The same is with a ribbon, (a good example of that design is a printer where you will see it spin the feed wheels and move the heads from side to side on startup to calibrate it's self) Usually electronically controlled valves do not need any user adjustment for calibration. (at least with heating and cooling systems)
The veins have valves in them
There are one-way valves (leaflet valves) in the veins which normally allow blood to flow only back to the heart. Muscle pressure is the main force pushing blood back from the extremities, especially against gravity in the legs. When the valves malfunction or are affected by high blood pressure, the vessels can form varicose (swollen) veins, blue veins, or spider veins.
Shift points are controlled by the engine computers activation of a governor pressure solenoid. The governor pressure activates valves in the transmission that switch gears.
Solenoid valves are electromechanically operated valves which are controlled by an electric current, mostly used in fluidics. There are different types of solenoid valves, one or two port valves.
They are located internally in the transmission itself.
Yes it can! EGR valves use engine vacuum, as does the transmission
Normally no.
Normally they're called valves. There are some trumpets out there with rotary valves, which are often just called keys.
the 2.5 and the 2.8 are controlled by hydraulic lifters, they are non-adjustable.
The popular Bugatti Veyron has four valves per cylinder, a dry sump lubrication system, electronically controlled cam timing, and a large radiator. These features allow it to go very fast without taking up too much room and making the car bulky.
