A miniature low-flow, fluid conserving washer nozzle has an elongated housing enclosing an interior volume aligned along an inlet axis which receives an elongated insert member with internal fluid passages defining first and second power nozzles, so that accelerating first and second fluid flows are aimed by the first and second power nozzles toward one another in an interaction region defined within the insert with an insert throat to aim spray laterally or transversely along a spray axis through an aligned sidewall aperture in the nozzle housing. The nozzle may generate a planar oscillating sweeping fan of spray, produced by fluidic oscillations at low flow rates, typically 150-300 ml/min at 25 psi. The fan of spray generated may be varied from 20° to 70° or about 15°-60°. The outer dimensions of spray head could be as small as 3.5 mm. The fluidic geometry is also capable of spraying high viscosity liquids up to 25 CP or up to 15 CP.
