How A Bicycle Pump Works By; Alyssa Horan and Ashley Tomlinson 1. The user lifts the handle which causes the piston to lift, soon after air draw into the pump. 2. Air enters the compression chamber as the inlet valve opens. After the air is in the chamber it is ready to be compressed. 3. The user now lowers the piston which causes the inlet valve to close, this means the air has no where to go except into the hose and then the tire 4. The outlet valve opens shortly after because of all the pressure. This valve is a one way valve so all of the air is pushed in ONE DIRECTION. 5. Lastly the air is pushed out of the chamber causing it to enter the tire. Every downward stroke of the piston inflates the tire more and more. THE END 3. Piston lowers 4. Outlet opens 5. Air inflates tire These steps will be described in greater detail later on. We hope that this helped you understand how a bicycle pump works!! WE had a lot of fun making this prezi!!! Thank for watching!!! Steps in Greater Detail AND always remember to eat your carrots :D
(it helps your eyesight \(^.^)/ ) AND always remember we LOVE One Direction Basic Steps Whenever you are using a bicycle pump there are 5 easy steps to explain how the pump works 1.Piston rises 2. Air enters chamber Parts of the Pump Body of the pump; outside of the pump. Compression chamber; A chamber that stores the air inside the pump. Hose; Attached to the compression chamber and the tire valve. Piston; An object that moves up and down, compressing air while doing so and forcing air into the tire. Handle; The user holds this while pumping to control the piston. Inlet valve; Allows air to enter the compression chamber but most importantly keeps it inside of the chamber. Outlet valve; This valve lets air flow into the tire but also keeps the air inside the tire. Hi I Love Niall :D 1. 2. 3. Hi I Love Louis :D 4. 5. 6. 7.
