As shown by the above image, when a liquid or gas flows into a flow direction (right direction), the spring is pressed by the flowing liquid and the oil passage is opened. In consequence, the fluid flows. If the fluid tries to flow in the reverse direction of the flow, the spring recovers its original shape and closes the oil passage, preventing the reverse flow of the fluid.
