The spring exerts stress on the retainer to keep the valve closed. When the rocker arm in a pushrod engine or the cam follower in an OHC engine moves and pushes the valve open, the strain on the spring causes it to move back and forth between the open and closed position. When the engine is running, this strain is relieved by the compression stroke of the crankshaft.
This compressing of air causes the valves to open and close. The valves are closed when the pistons are at the top of their stroke, and open when they are in their bottom stroke. In the case of an open valve, air is forced into the combustion chamber and out the exhaust port. It is the opposite of a valve that is open.

What is a valve spring compressor used for?
A valve spring compressor apparatus and method for compressing cylinder valve springs for the removal and installation of their locks or keepers and for replacement of valve stem seals or broken springs on an internal combustion engine, while the cylinder head is in the closed position. The invention relates to the compression of cylinder valves, and more particularly to a valve compression device for use in a cylinder engine.
The invention comprises a compression chamber, a piston, an annular piston ring and a cylindrical piston sleeve. This compression is achieved by means of a plurality of compression pistons, each of which is connected to one or more compression springs.
Each compression piston is provided with a first end and an intermediate end, said first and intermediate ends being adapted to be connected by a connecting rod or other suitable means to each other, so that when the first piston of each pair of pairs of piston rings is pressed against the second end of one of its pairs, it compresses the other piston in turn, thus causing the cylinders to move in unison.
How does a valve compressor work?
A series of plates or rings sandwiched between the valve seat and cover are what Compressor valves are. When a pressure difference occurs, the rings or plates are pulled toward the area of greater pressure and use springs to return them to their original position. A compressor valve is designed to operate at a constant pressure.
If the pressure is increased or decreased, a valve will open or close depending on the amount of force applied to it. The pressure in a compressor is measured in pounds per square inch (psi) and is expressed as a percentage of the rated capacity.
For example, if the compressor has a capacity of 10,000 psi and the air is compressed to 10 psi, it will be at 10% of its capacity when it is opened. A pressure of 100 psi will cause the valves to open and close at the rate of 1 psi per second.
What happens when valve spring tension is too high?
When the spring tension is too low, valves will float and cause engine damage. Valve timing is the process by which the valves open and close. The timing of a valve is determined by the amount of pressure applied to the valve stem. Valve stem pressure is measured in pounds per square inch (psi). The higher the pressure, the greater the opening and closing time for a given valve.
A valve with a pressure of 2,500 psi closes and opens in 2.2 seconds, and so on. In order for valve timing to be accurate, it must be measured at the same time every time. This is why it is important to have a timing gauge on your car. It will allow you to measure the timing at any time of the day or night, even if you are not driving the car at all.
How much valve spring pressure do I need?
To prevent the valves from bouncing on the seat, elevated seat pressures are required. Street-strip cars should aim for ~175-200lbs seat pressure. Mild race applications need 225-250lbs on the seat. Professional level racing require ~350lbs. If you’re not sure how much pressure you need, you can measure it with a caliper. If you don’t have one, get one from your local auto parts store.
It will cost you about $20, but it will give you a good idea of what the pressure should be for your application. You can also buy a pressure gauge from a car dealership. The gauge will tell you what pressure your car is at, and it can be used as a guide to determine the correct amount of pressure to apply to the valve.
How do I know what valve springs to use?
Most manufacturers will recommend valve springs to go with each camshaft they make. The camshaft manufacturer recommends the same springs or springs with the same specifications. Understanding the spring specifications will help you choose the right springs.
Why do valve springs break?
To maintain correct valve operation at normal engine speeds, all of the valve springs have to exert a certain amount of spring pressure. Too low or week valve spring pressure can cause valves to not completely seal or float. Valve springs are made up of two main parts: the piston and the camshaft. When the pistons move, they compress the air in the cylinder, causing it to expand.
This expansion causes pressure to build up inside the cylinders. As the pressure builds up, a valve opens, and air is allowed to flow from the intake manifold to the exhaust manifold. In the case of an engine that has been running for a long period of time, this expansion of air can cause the engine to overheat, which can lead to engine failure.
To prevent this from happening to your engine, it is important to properly lubricate your valves, as well as your intake and exhaust manifolds. If you have not done so, you may find that you are not able to open and close your valve properly. Manifold.
