摘要:
A trigger sprayer includes an engine with a piston chamber and an outlet fluid passage, and a piston that slides within the piston chamber and defines an interior bellows chamber. The bellows component is movable in the interior bellows chamber between an uncompressed position in which a fluid volume in the interior bellows chamber is minimized and a compressed position in which the fluid volume is maximized. The trigger sprayer further includes a trigger lever that pivots between a neutral position and an actuated position using a pair of S-shaped trigger springs. Pivotal movement of the trigger lever pushes the piston vertically in the piston chamber to drive fluid from the piston chamber into the interior bellows chamber and move the bellows component from the uncompressed position to the compressed position. Relaxation of the bellows component drives fluid from the interior bellows chamber to the outlet fluid passage.
