When the pump arm nods down, the traveling valve pushes down. The pressure closes the standing valve (so oil doesn't push back into the ground) and forces the traveling valve to open. The oil passes through the traveling valve, ready to be lifted to the surface on the next upstroke. ⏳ A Century of the "Nodding Donkey"

When the pump arm at the surface nods up, it pulls the traveling valve upward. This creates a low-pressure vacuum in the chamber below it. The standing valve opens, and oil rushes into the pump barrel from the surrounding earth. oil_pump_schematics.part3.rar

: Walter Trout, an engineer for the Lufkin Foundry and Machine Company, revolutionized the industry. He invented the counterbalanced crank beam pumping unit. By adding a heavy counterweight to the rotating crank, he balanced the massive weight of the thousands of feet of steel rods hanging in the well.
