Glossary “rotor pump” Definition:
A positive-displacement pump that uses an inner drive rotor and an outer drive rotor to produce an oil flow. Lobes on the rotors create a fluid chamber of varying volumes and eliminate the need for a crescent as used in a gear pump.
What is rotor?
rotor runout
Glossary “rotor runout” Definition:
The amount of runout measured at the brake rotor face as it is rotated.
rotor face
Glossary “rotor face” Definition:
The flat, parallel surface on each side of the rotor contacted by the pads (linings) during stopping.
rotor
Glossary “rotor” Definition:
1). Disc-shaped component that revolves with hub and wheel. The brake pads are forced against the rotor to provide a friction surface for the brake system, so as to slow or stop a vehicle. 2). In a conventional ignition system, the part that transfers the secondary voltage from the center terminal to the outer terminals of the distributor cap as it rotates inside the cap. 3). The rotating part of an alternator that reacts to the magnetic field to create a current flow.
rotor oil pump
Glossary “rotor oil pump” Definition:
Type of oil pump in which a pair of rotors produce the pressure required to circulate oil to the engine parts.
