Mini Trigger Sprayer pumps have a really straightforward design and work with several parts to make sure the pumping action delivers liquid in the bottle as a spray. The trigger lever, once pulled using a few fingers activates a small pump. This pump is attached to a plastic tube that draws cleaning fluid from the bottom of the reservoir inside the bottle. The pump forces this liquid down a narrow barrel and out a small hole at the spray valve.

　　Inside the shroud, there is a small spring which compresses the fluid once pulled back by the trigger. The moving piston compresses the spring, so when you release the trigger, the piston is pushed back out of the gasket. These two strokes of the piston move the cylinder out again and contribute to the entire pump cycle.

　　This extraction motion shrinks the cylinder and forces the fluid out as a one-way system. Once the trigger is released, the motion allows the processes to be repeated without any delivery problems. Slightly different designs are used depending on the pump type and delivery solution.

　　Solving these problems

　　These two problems are solved with the use of simple connections that allow fluid to move in only one direction. If we put one in between the reservoir and the staging area, we will never have to worry about fluid going from staging back to reservoir. This solves our first issue. If we also put one in the nozzle such that fluid can only move from staging to the nozzle, the air would never come into the staging area when we relax the trigger.

　　Very helpful. We can construct a very simple one-way connection using three main components: a ball, a spring, and a cylinder with a hole in one end.
