Advanced CNC-controlled machining centres enable rotor profi les and gears to be precision machined within a tolerance of a thousandth of a millimetre. The resulting nominal clearance between the rotor lobes and casing ensures high volumetric effi ciency and minimal heating of the block. All block casings and rotors are manufactured within exact tolerances to guarantee consistently high product quality.
As the rotors turn, air in the inlet is trapped between the rotor lobes and the casing and is carried round to the outlet without being compressed. The casing bore toward the discharge port is slightly eccentric so that as the lobe approaches the port the gap between it and the casing begins to widen. This allows gradual equalisation of pressure between the air in the discharge port and that in the chamber behind the advancing lobe. Pressure equalisation in two-lobe blocks occurs abruptly as the advancing lobe crosses the lip of the discharge port. This is the main reason why three-lobe blocks generate signifi cantly less pulsation than two-lobe blocks. The air is then fi nally pushed out against the pressure in the pipe work.
