Car Inflator Pump Demo Car Inflator pump, also known as inflator, inflator, inflatable pump, through the operation of the internal motor to work. In daily driving, due to uneven tire pressure caused by accidents have occurred, we can see at any time to maintain the tire pressure is so important. High-speed driving, inflatable pump burst phenomenon occurred, mainly due to low tire pressure and tire pressure caused by high. Therefore, driving, carrying a better quality car air pump, to ensure that the inflated tires at the same time, but also improve driving safety and prolong the service life of the tire. When the gas is exhausted, the valve of the communicator is opened by the atmospheric pressure and the gas enters the gas cylinder. When the gas is inflated into the tire, the valve is closed by the gas pressure inside the gas cylinder, and the gas enters the tire, which is also the principle of using atmospheric pressure With the car, the ball, inflatable rubber boat.
