Which way do gears turn? Change direction: When two gears mesh together, the second one always turns in the opposite direction. So if the first one turns clockwise, the second one must turn counterclockwise. You can also use specially shaped gears to make the power of a machine turn through an angle. Which way does […]

What does a brake combination valve do?
What does a brake combination valve do? Most combination valves perform 3 functions: The Proportioning Valve keeps the rear brakes from locking up during a panic stop. The Metering Valve delays the front brakes long enough for the fluid pressure to overcome the rear brake return springs. A pressure switch sends an electrical signal. What […]
How does a diaphragm pressure sensor work?
How does a diaphragm pressure sensor work? The Diaphragm Pressure Gauge uses the elastic deformation of a diaphragm (i.e. membrane) instead of a liquid level to measure the difference between an unknown pressure and a reference pressure. A typical Diaphragm pressure gauge contains a capsule divided by a diaphragm, as shown in the schematic below. […]
