Definition of portable air compressors and what types  could you  pick from?<br><br><br><br><br>An air compressor is a device that converts power (using an electric motor, diesel or gasoline [https://www.google.com engine], etc.) into potential energy stored in pressurized air (i.e., compressed air). By one of several methods, an air compressor forces more and more air into a storage tank, increasing the pressure. The energy contained in the compressed air can be used for a variety of applications, utilizing the kinetic energy of the air as it is released and the tank depressurizes. <br><br>Air compressor types<br><br>And while there are compressors that use rotating impellers to generate air pressure, positive-displacement compressors are more common and include the models used by homeowners, woodworkers, mechanics and contractors. Here, air pressure is increased by reducing the size of the space that contains the air. <br><br>Just like a  little internal combustion engine, a  traditional  engine compressor has a crankshaft, a connecting rod and  engine, a cylinder and a valve head. The [http://search.huffingtonpost.com/search?q=crankshaft&s_it=header_form_v1 crankshaft] is driven by either an  electrical motor or a gas engine.  Although there are small  versions that are  consisted of just the pump and motor, most compressors have an air tank to  contain a quantity of air within a preset pressure range. The compressed air in the tank  steers the air tools, and the motor  moves on and off to automatically  sustain pressure in the tank. <br><br>At the top of the cylinder, you'll  discover a valve head that  secures the inlet and discharge valves. Both are simply thin metal flaps-- one mounted underneath and one  placed  at the top of the valve plate. As the piston  goes down, a vacuum is  produced  over it. This allows outside air at atmospheric pressure to push open the inlet valve and fill the area above the  engine. As the piston moves up, the air above it compresses,  keeps the inlet valve shut and pushes the discharge valve open. The air moves from the discharge port to the tank. With each  movement, more air  goes into the tank and the pressure  arises. <br><br>Typical compressors  can be found in 1- or 2-cylinder versions to suit the requirements of the tools they power. On the homeowner/contractor level,  a lot of the 2-cylinder  versions  work just like single-cylinder versions, except that there are  2 strokes per revolution  rather than one. Some commercial 2-cylinder compressors are 2-stage compressors-- one  engine pumps air  in to a  2nd cylinder that  even more  boosts pressure.<br><br>Compressors use a pressure switch to stop the motor when tank pressure reaches a preset limit-- about 125 psi for many single-stage models. The air line will include a regulator that you set to match the pressure requirements of the tool you're using. The pressure switch may also incorporate an unloader valve that reduces tank pressure when the compressor is turned off.
