Vapour

Minute airborne droplets of a liquid or liquid that has been heated to a gas state.

Vapour Lock

Vapour formation in a fuel line caused by heat. The effect is similar to an air lock and acts to prevent fuel delivery. To clear the vapour lock the fuel line must be bled or allowed to cool.

VAPS

Variable assist power steering

Variable Choke Carburettor

A carburettor with a variable diameter venturi (choke tube). The variable diameter is obtained by inlet manifold vacuum being applied to one side of a diaphragm or piston and atmospheric pressure to the other side. This arrangement produces a constant depression and relatively accurate fuel metering.

Variable Resistor

A resistor that can have its value changed manually.

Variable Venturi

A venturi (narrowing of a tube) that can be changed. Usually refers to a carburettor. See also Variable Venturi Carburettor.
