Claim 5:
6. A method of assembling a trigger sprayer assembly, comprising:
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;
inserting a piston component into the piston chamber by moving the piston component along a piston axis;
coupling a trigger lever to the engine and the piston component by moving the trigger lever along a trigger axis, wherein 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; and
coupling a shroud to the engine by moving the shroud along a shroud axis;
wherein the trigger lever comprises a pair of trigger springs, and coupling the trigger lever to the engine comprises inserting a terminating end of each of the pair of trigger springs into one of a pair of spring recesses formed in the engine; and further
wherein the shroud comprises a pair of spring retaining ledges extending from an interior surface of the shroud, each of the pair of spring retaining ledges configured to fit into the spring recess of the engine to constrain lateral movement of the terminating ends of the trigger springs;
wherein the piston axis, the trigger axis, and the shroud axis are parallel to each other; and
wherein at least one of inserting the piston component, coupling the trigger lever, and coupling the shroud is performed using a robotic assembly device.
