作用を行うものである。 Vehicles such as automobiles are usually equipped with window washers to ensure the driver's forward visibility. This is a device that uses a washer pump to pump up cleaning fluid from a reserve tank installed under the bonnet of a car that stores cleaning fluid, and sprays it onto the windshield through a nozzle, which is then used in combination with a wiper to clean the windshield. Also, as a device that doubles the driver's pressing force on the brake pedal to perform a braking action,
Some automobiles are equipped with pneumatic brake boosters.
This is used to store compressed air from the pump.
The compressed air is stored in a tank and is introduced into a brake booster according to the amount of depression of the brake pedal to perform a boosting action.
