A set of helical gear pairs having various...

... shafts A positive displacement machine processes its working fluid by confining it to a sealed volume that decreases (or increases) with the angle rotated by the crankshaft. Machines that handle gaseous fluids are referred to as compressors, if they are meant to impart pressure to the working...
