Upper tension regulator is a part of a sewing machine which is a dial or disk that controls the tightness (tension) of the upper thread.
Mechanism which controls delivery of upper thread.

The upper tension regulator on a sewing machine adjusts the tension on the upper thread. This helps ensure that the stitches are formed correctly and evenly, with the right amount of tension to hold the fabric layers together. Proper tension adjustment is important for producing high-quality sewing projects.
It regulates the thightness or lossness of the thread.
The presser foot is a special part of the machine that holds the fabric down so the stitches remain even. I have not seen a pressure regulator on a home sewing machine.
To restore tension in the window spring of a 1992 Firebird passenger side window motor, you need to remove the door panel to access the motor and regulator assembly. Carefully detach the motor from the regulator to access the spring mechanism. Using a suitable tool, such as pliers, you can manually wind the spring to increase tension, ensuring it is securely reattached to the regulator. Reassemble the motor and door panel, ensuring everything is properly aligned and secured before testing the window operation.
If you are replacing the regulator anyway, it comes with the new cables, so just use wire cutters to cut the old wires near the regulator. this will free the tension on the track, so you can lift the window.
1943Emile Gagnan and Jacques Cousteau invented the modern demand regulator and an improved autonomous diving suit. In 1942, redesigned a car regulator and invented a demand regulator that would automatically fresh air when a diver breathed. A year later in 1943, Cousteau and Gagnan began selling the Aqua-Lung.
Which regulator and what year? You have a window regulator, voltage regulator, fuel pressure regulator to name a few.
A drum tuner is used to tune drumheads by adjusting the tension. Marlon Brando invented the first automatic tuner, to easily adjust the tension in all the heads.
Oil pumps have a spring operated regulator and the spring's tension determines the max oil pressure.
