enough oil escapes to maintain the pressure

That the valve does not normally actually move back and forth in a real physical sense of motion. In operations, the valve maintains a constant pressure overall by bleeding off more or less oil from the pump itself. On the other side of the road, when pump pressure is low, spring force will push the valve to the other side closing off the return line to its hydraulic reservoir. Pump pressure entering the output-pressure line is reduced essentially because the valve has positioning itself to allow excess oil to escape though the line. This causes the boost valve to add to the forces of the spring in the pressure regulator valve. As the valve moves back, it uncovers an opening or port, which is connected to a return line to the oil reservoir. Now part of the oil from the pump can flow through the return line. Since less oil can now escape, the oil pressure goes up and the valve is again moved back. Then, if the incoming oil volume changes because if a change in pump speed or speeds, the valve position will change. Just enough oil escapes to maintain the pressure in the output line at the value determined by the valve spring. This would produce excessively high pressure if it were not for the action and actions of the pressureregulator valve and valves.As the pressure and pressures go up and thus increase overall. There is increasing force and power exerted onto the valve. The valve moves back into its cylinder bore.

For example: suppose the pressure source is an oil pump driven by the engine. This reduces the pressure so that valve starts forward again, moved by the force of the spring. When the engine runs at high speed, this pump also runs and functions at high speed. In the actual transmission, the pressure-regulator valve is used with one or more boost valves in line with it. This article is part 1 of a two part article  dealing in this case with the first type of automatic transmission valve type  that being pressure-regulator valve types. The valve setup is that it is spring-loaded and has a small piston that can move back and forth in a cylinder bore.All in all it might be said.Simply put and explained the pressure regulator valve uses simple standard hydraulic action to prevent excessive pressure in any hydraulic system that it is used and employed in.

Valve movement produces a constant pressure from a variable pressure source. The result is that the output pressure is increased or boosted. However, as the valve moves forward, it partly shuts off the port to the return line.If you are driving your vehicle down the road or highway in whether it is a truck, Sports Utility Vehicle, bus or even automatic transmission highways traffic trailer or even earth mover it is a bet that you have either type of hydraulic valve  either a pressure regulator valve or valves or the balanced type valve to thank for your reliable travels and transport down the road, street or highway. Instead it seeks and finds the very position at which oil pressure just basically balances spring force.Automatic transmissions system whether they are used to drive and power cars, trucks or tractor trailers use two different basic systems in their automatic transmission power transmission systems.

Under certain conditions, a boost valve will have oil pressure applied to it.The output-pressure and pump-pressure lines do not actually have to run the piston or any pistons in actuality in automatic transmissions. When the preset valve (which is simply determined by the force of the spring is reached, the oil pressure overcomes the spring force.For example as the pump speed goes up China Foot Valves Suppliers which means essentially that the pump delivers more oil and the pressure goes up  the valve is forced to open and port wider. Therefore if delivers a large volume of oil. This permits more oil to flow into the return line, preventing excessively high pressure and pressures. The two basic different types of hydraulic valves that are used in automatic transmissions are first the pressure-regulator valve type and the balanced valve hydraulic setup. You can count on it that all of the valves found in 2010 / 2011 employed and used in your vehicle today is either one of these two family types.
