VACUUM PUMP

摘要

A vacuum pump may include a stator located between an intake plate and a back plate. Mating portions on the intake plate and back plate may be used to properly locate the stator. The stator may comprise a tubular piece of material. The stator may include two internal pump chambers separated by a divider plate. In some embodiments, the divider plate may have a fluid passageway extending therethrough. A rotor in each chamber may include vanes and may be offset from the center of the chamber. Each rotor may be fixed to a rotatable shaft for operation of the vacuum pump.
