Abstract
An improved nozzle unit for periodically dispensing a fluid. The nozzle unit includes a fluid dispensing component mounted for confined displacement in a housing having first and second stop surfaces. The fluid dispensing component, when subjected to a displacement force produced by fluid flowing into the housing under pressure, moves from a primary stored position against the first stop surface to impact the second stop surface in a deployed position in which fluid flows through the dispensing component. At least one of the dispensing component and the housing is shaped and dimensioned to cause fluid flowing through the housing under pressure to produce fluid flow forces counteracting the displacement force which moves the dispensing component from the stored position to the deployed position. The fluid flow forces counteracting the impact force minimize material fatigue caused by the impact force and extend the operational life of the nozzle unit.
