Thexton
Glossary “Thexton” Definition:
Aftermarket tool manufacturer
thick film integrated module (TFI)
Glossary “thick film integrated module (TFI)” Definition:
Electronic module that is generallt mounted on the distributor and controls the ignition coil firing.
thermostatic pressure valve
Glossary “thermostatic pressure valve” Definition:
Valve that opens and closes in relation to temperature changes.
thermostatic switch
Glossary “thermostatic switch” Definition:
Term used for thermostat.
thermostatic vacuum switch (TVS)
Glossary “thermostatic vacuum switch (TVS)” Definition:
Valve that controls the passage of vacuum according to temperature, blocking vacuum until a certain coolant temperature is reached, at which point it opens.
thermostatic vacuum valve (TVV)
Glossary “thermostatic vacuum valve (TVV)” Definition:
Valve that is operational with a vacuum signal that is proportional to an applied temperature.
thermostatic gauge
Glossary “thermostatic gauge” Definition:
Type of gauge used to indicate fuel, engine oil, transmission and engine coolant temperature.
thermostatic clutch control
Glossary “thermostatic clutch control” Definition:
Method of temperature control using a thermostat to cycle a clutch on and off.
thermostatic de-icing switch
Glossary “thermostatic de-icing switch” Definition:
Thermostat that prevents the evaporator from icing up due to low temperature conditions.
thermostatic expansion valve (TXV)
Glossary “thermostatic expansion valve (TXV)” Definition:
The component of a refrigeration system that regulates the rate of flow of refrigerant into the evaporator as governed by the action of the remote bulb-sensing tailpipe temperatures.
thermostatic air cleaner
Glossary “thermostatic air cleaner” Definition:
Engine air cleaner assembly that controls the temperature of the intake air by blending relatively cool underhood or outside air with relatively hot air picked up from a shroud over the exhaust manifold.
thermosetting plastics
Glossary “thermosetting plastics” Definition:
Plastics which are heated during manufaturing and molded into a fixed shaped. After manufacture, the shape can not be altered by heat.
thermostat
Glossary “thermostat” Definition:
1). Driver operated device used to cycle the clutch to control the rate of refrigerant flow as a means of temperature control. 2). Temperature sensitive component located in a housing at the coolant outlet of the engine that restricts coolant flow to the radiator to maintain the desired engine-operating temperatures.
thermostat bypass
Glossary “thermostat bypass” Definition:
Small passage way that allows coolant to circulate when the thermostat is closed.
thermometer
Glossary “thermometer” Definition:
Device used to measure temperature.
thermoplastic plastics
Glossary “thermoplastic plastics” Definition:
Plastics that are flexible; that is, they can bend or flex and recover their shape quickly. They are affected by high heat.
thermoplastic seizure
Glossary “thermoplastic seizure” Definition:
When coolant has found its way into the engine oil, it can seize the engine.
thermoelectric meters
Glossary “thermoelectric meters” Definition:
Type of dash instrument that uses heat created by current flow through the gauge to deflect the indicator needle
thermoelectric principle
Glossary “thermoelectric principle” Definition:
Production of a voltage potential created by heating the connection of two dissimilar metals.
