Introducing and explaining the characteristics of one-way valve

One-way valves, to put it bluntly, allow only one-way flow of oil. Its usage is very flexible.
Basically, pump outlet, accumulator front, etc.
There is also as a selection valve, such as two one-way valves can be combined into a shuttle valve to select a high-pressure output; as a conditional valve to use, such as hydraulic control one-way valve, only to meet certain (pressure) conditions, can allow reverse flow of oil, the typical application is hydraulic lock! There are other valves used in combination, such as one-way throttle valve; back pressure valve, such a one-way valve has a certain pre-pressure; there is also a by-pass valve or safety valve, there are pre-pressure, usually in parallel with filters, radiator components.

In a word, the application of one-way valve is flexible and extensive. Find more hydraulic schematic diagram of actual equipment, after all, the teaching material is limited.
