The principles of window regulator work

The car VALEO brand Window Regulator acts as the simplest climate control system with which you can ventilate the cabin or saloon. Also, window regulators are among the measures to protect the car from unauthorized entry: they block the glass in a closed or partially open position, preventing free access to the passenger compartment through window openings.

The drive mechanism (or motor - reducer) in its action combines an electric motor, a gear and a worm gear, which are made in the form of a single block. This mechanism is necessary to create a force that will raise and lower the glass. Due to the use of a worm gear, the window cannot be accidentally opened. The worm gear is designed so that the transmission of rotation will go in only one direction - from the worm to the wheel.
