Bicycle and football pressure pump

This portable air pump can be used to pump different types of balls and bicycle tyres. This pump has the capacity to inflate other inflatable products such as inflatable beds, swimming pools, arm floaters, swimming rings etc. The pump compresses air. When the cylinder is compressed, air is pushed down the tube of the pump and then into the tyre/ball via the valve, which is forced open by the pressure of the air. When the handle is pulled up again, the valve shuts off automatically so that the air cannot escape from the tire, and new air is forced back into the cylinder so the process can be repeated. Once the tyre/ball has been pumped to the desirable size, the pump valve can be removed from the tyre, and the cap can be replaced on the tyre valve. This pump has the capacity to inflate other inflatable products such as inflatable beds, swimming pools, arm floaters, swimming rings.
