Morphology

throttle + valve

The meaning 'a valve that regulates the supply of fuel or air' is directly derivable from combining 'throttle' (a device/lever that regulates flow) with 'valve' (a flow-control device). This is a regular noun–noun compound following standard compositional patterns, so a B1 learner who knows both constituents will readily infer the MWE meaning.

Etymology

The noun throttle valve is a simple image: a valve that throttles the flow of air and fuel into an engine. By letting in more or less flow it 'controls' the engine's 'speed', so the name shows its job.
