Abstract:
A fluid dispensing device, comprising:a valve body defining a longitudinal opening therein;an inlet in flow communication with the longitudinal opening, the inlet defining an axis generally transverse to the longitudinal opening;an outlet defined by a first end of the longitudinal opening;a sealing member having first and second sides situated within the longitudinal opening;a valve stem linearly movable within the longitudinal opening and adapted to seat against the first side of the sealing member to control fluid flow from the inlet to the outlet;a nozzle having a first end coupled to the valve body adjacent the outlet and a second end defining an annular ledge, the nozzle defining an opening therethrough such that fluid can flow from the outlet through the nozzle;a conical spring having first and second ends, the first end seated on the ledge; anda diffuser including:a first generally cylindrical portion having a sidewall defining a diameter and a top end including a circular flat portion defining a plane oriented generally transverse to the axis of the longitudinal opening and defining a diameter smaller than the diameter of the sidewall, anda second generally cylindrical portion defining a diameter smaller than the sidewall diameter, the second portion extending coaxially from the first portion so as to form a circumferential ledge with the first portion, the second portion being received within the second end of the spring wherein the spring normally biases the diffuser against the second side of the seal member;such that fluid flowing from the outlet pushes the diffuser against the spring, and the fluid flows around the diffuser and through the sprint as the fluid exits the nozzle second end.
