  "textContent": "A compact EGR valve uses a BLDC motor to drive a valve member between a closed position blocking flow of exhaust gases and a range of open positions where exhaust gasses flow through the valve. A drive mechanism includes a nut in a fixed position and a screw arranged to rotate within the nut so that rotation of the screw causes the screw to move axially relative to the nut. The screw is coupled to a valve member and the valve member moves axially and rotationally with the screw. The screw slides along the length of a motor shaft as the screw moves axially relative to the nut and motor. Rotation of the valve member within the valve chamber during axial movement aids in removal of deposits that may accumulate within the valve housing.",
