Any motorist knows about the need forin the trunk of his car a number of accessories that will help in an unforeseen situation. After all, on the road, especially distant, anything can happen. One of these assistants will serve as an automobile pump. If suddenly the car has lowered the wheel, you do not have to use the services of an evacuator or an on-site technical service, it's enough to pump the bus yourself with this device.
Manual car pump is aoblong metal cylinder with a hose, on the one hand, and with a handle-piston for air injection, on the other. Rarely, which motorist uses a hand pump - too much time and effort will be spent on swapping an automobile wheel.
The foot pump consists ofa metal casing located on the landing pad, a hose connected to the casing, and a piston with a foot operated mechanism. Most modern pumps also have a manometer. This allows you to monitor the pressure in the inflated tire.
There are membrane and piston electric pumps. Membrane devices are not very popular among motorists. For pumping the wheel with their help takes more time, while not providing the desired pressure in the tires. They are completely unsuitable for use in the cold season: the rubber membrane hardens at minus temperature and makes operation of the device more difficult.
Thanks to the availability of a number of adapters, auto pumps can be used for pumping motorcycles, bicycles, inflatable boats, balls, mattresses.
