    摘要: A trigger sprayer assembly is provided. The assembly includes an engine having a piston chamber and a fluid passage that extends from an inlet portion to an outlet portion, a piston having a plunger that is disposed within the piston chamber, and a trigger lever that is configured to pivot between a neutral position and an actuated position. The assembly further includes an input valve and an output valve configured to control unidirectional fluid flow through the inlet and outlet portions of the fluid passage. The input valve includes a cylindrical body terminating in a flap portion. Pivotal movement of the trigger lever from the actuated position to the neutral position pulls the plunger out of the piston chamber such that the flap portion of the input valve pivots from a closed position to an opened position and fluid flows through the input valve and into the piston chamber.

    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.

    摘要: A method of assembling a trigger sprayer assembly includes providing an engine having a piston chamber and a fluid passage that is fluidly coupled to the piston chamber, the fluid passage extending from an input portion to an output portion. The method further includes inserting a piston component into the piston chamber, and coupling a trigger lever to the engine and the piston component. Pivoting the trigger lever relative to the engine pushes and pulls the piston component within the piston chamber to drive fluid from the input portion to the output portion of the fluid passage. The method further includes coupling a shroud to the engine, where the coupling comprises positioning a rail protrusion of the engine within a corresponding recess formed in the shroud, and inserting a shelf extending from an interior surface of the shroud into a pair of receiving clips extending from the engine.

    摘要: A trigger sprayer assembly for dispensing a fluid is provided. The assembly includes an engine having a piston chamber and an outlet passage that is fluidly coupled to the piston chamber, a piston having a plunger and an intermediate portion that extends from the plunger and terminates in an end portion, a trigger lever having a main body and a piston coupling body, and a pair of trigger springs coupled to the main body. Each trigger spring includes a first curved portion, a second curved portion, and a terminating portion. The terminating portions are configured to fit within recesses formed in the engine, and the piston coupling body engages with the end portion. Pivoting the trigger lever from a neutral position to an actuated position compresses the trigger springs and pushes the plunger into the piston chamber to drive fluid into the outlet passage.
