It helps the valve close after it has been opend
The main purpose of a valve spring is to maintain pressure and ensure that the valves close properly after they have been opened by the camshaft. It helps keep the valves in contact with the camshaft lobes and prevents them from floating or bouncing at high engine speeds. Ultimately, this allows for efficient and precise control of the engine's valve timing and operation.

the spring.
The main purpose of the Bill of rights, was to protect individuals from government abuse.

The valve spring is the spring that closes the valve in the engine head after the cam lobe or rocker opens it . If the valve didn't close, many things would happen , the main one being the motor would not fire .
The purpose of the valve spring is to maintain contact between the components in the valve train, so the valve motion will follow the cam profile.

The purpose of the valve spring is to close the valve when the cam has finished pushing it open to allow fuel/air in or exhaust gases out. The spring is held in place at the top of the valve by a split-collet, like 2 halves of a cone, and also sits against the outside of the cylinder head. The spring is compressed when the cam on the cam shaft pushes it down, and as the cam moves away, the spring forces the valve shut again.
To retain the valve to the valve spring, could also be called keepers
If only one spring were used on each valve, the valve would surge and bounce because of the natural vibration frequency of the spring.
A valve spring "keeper" or AKA a valve spring "retainer" is used to lock a valve spring to the valve.
Valve pocketing is when a valve is hammering the valve seat.mostly due to miss adjusted valve spring/wrong valve spring/to strong of a valve spring or valve stem to short.Makes the valve seat deeper.
the purpose of it is to connect the valve springs to the spring keeper to make a vale-springkeper it helps maintain the engine so it doesn't blow up and so the engine doesn't ignite
how many positions does a spring offset valve have
you need to compress the spring with a valve spring compressor tool, and then remove the valve keepers, and retainer.
A valve will be fitted so that if part of the fire main is damaged it can be isolated from the supply. That way the rest of the main is still usable and can be used for firefighting.
