On a large cutting board, place the flour in a large mound. Make a crater in the center and add the eggs, olive oil, and salt. Using a fork, slowly incorporate the flour into the eggs. When the dough becomes very thick, use your hands to finish mixing the dough. You may not need all the flour for your dough.
Knead the dough for 5 minutes or until it's smooth. Cover it with a bowl and let it rest for 30 minutes. Meanwhile, mix the ricotta, Parmesan, egg yolks, and salt together, for your filling.
Cut the dough into 6 equal pieces. Cover 5 pieces with a towel. Roll the sixth piece into a small rectangle, dust it with flour, and feed it into the pasta machine, on the thickest setting. Repeat feeding it through the machine, using a narrower setting each time, until the dough is very thin. Repeat with the remaining 5 pieces. After you roll out each piece of dough, cover it very loosely with plastic wrap.
Lay out one strip of dough at at time, and put teaspoons of filling in a line, about two inches apart, in the upper half of the dough strip. Dab water all around the cheese, fold the bottom of the dough on top of the cheese, and then cut it with a pastry or pizza wheel.
Bring a large pot of salted water to a boil, and cook the ravioloni in 4 batches for about 5 minutes each. Drain and serve with Pomodoro Sauce.
