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 .

How can you tell it's an interference engine or If it's a non-interference engine?

If you give the yr/make/model/engine, could let you know... But if you want to find out your self. You need to turn piston 1 to TDC and depending on the engine, undo the valve spring keeper and measure how far the valve drops until in hits the piston. Subtract .050 of an inch and if it is less than the max valve lift you have an interference engine.


What is the use of valve spring?

Valve springs keep valves firmly seated in the socket.


What is salonoid valve?

A solenoid valve is a valve controlled by an electrical coil. A spring keeps the valve closed. When power is turned on to the coil, a plunger is pulled, opening the valve.


What is the purpose of the pressure regulation valve?

To regulate the pressure to a pre-determined amount.


Why are direct acting relief valves not used on high pressure and high flow hydraulic systems?

As a direct relief valve opens, its spool or poppet pushes against a spring. As the spring compresses, the system pressure necessarily rises due to the spring constant. To handle large flows, you need a big valve. To minimize the pressure rise due to the spring constant you need a long spring. To minimize the pressure drop due to the valve body, you need a big valve body, which in turn needs a bigger spring. As the operating pressure goes up, you need stiffer (typically bigger)springs. Eventually the cost of the valve is prohibitive and a pilot operated valve is called for. There are benefits to using direct operated valves which may out weigh the costs, but most direct operated valves are limited to medium and low pressure settings.

What is the purpose of a valve spring in an engine?

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.

What is the purpose of the valve spring keepers?

Valve spring keepers, also known as retainers, serve to secure the valve spring in place on the valve stem in an engine. They prevent the spring from dislodging during operation, ensuring that the valve remains properly seated and functions correctly. By maintaining the correct valve lift and preventing misalignment, keepers play a crucial role in the overall performance and reliability of the engine's valvetrain.


What is the main purpose of a valve spring?

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.


What is the purpose of the inlet valve in a petrol engine?

it is too squease all the fluids into the engine too allow lubrication of the body this lubrication creates extatic movement allowing for a senstational ride


How do you know if your valve spring is brocken?

Your engine will probably missfire and you will not have compression in the cylinder that has the broken valve spring because your valve will stay open.

How does an engine exhaust valve get bent?

the valve bent because the piston hit it, due to a weak valve spring or over revving the engine


What is the purpose of the valve spring?

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.
