GLOSSARY CONT’d :
Oil Filter The part of the lubricating system that removes dirt and dust from the oil circulated through it.
Oil Seal A seal placed around a rotating shaft to prevent the escape of oil.
Overrunning Clutch A type of clutch which will transmit rotary motion in one direction only.
Pump A device to produce motion of liquids. In the torque converter it is the driving member.
Reactor The stator in the torque converter which provides reactive blades against which the oil can change direction.
Sprag Unit A form of overrunning clutch ; power can be transmitted through it in one direction, but not in the other.
Stator In the torque converter, a third member which changes the direction of oil under certain operating conditions (when stator is stationary).
Torque Turning or twisting effort, usually measured in foot pounds.
Torque Converter A device in the power train consisting of three or more rotating members, which transmits power through a fluid. It provides varying drive ratios ; with sped reduction, it increases torque.
Torus Rotating member of the fluid coupling (driving or driven torus).
Turbine A mechanism containing curved blades, the turbine is driven by the impact of oil against the curved blades. The driven member of the torque converter.
