A fluidic oscillator for issuing a sweeping jet of air has a continuous inertance loop which has a section passing through the power nozzle of the fluidic oscillator. The continuous inertance loop is essentially coplanar with the plane of the fluidic oscillator so the basic oscillator element can be two identical molded parts which snap fit together.

Continuous inertance loop connectable at its ends to a pair of control ports of a fluidic oscillator, comprising, a pair of matching sections, each of said matching sections having gradually varying cross-sectional areas for coupling the respective ends of said loop to said control ports, said matching section being of largest cross-sectional area at said control port, and of smaller cross-sectional area at the opposite end thereof, a pair of loop sections of uniform cross-sectional area substantially equal to the cross-sectional area of the said smaller cross-sectional area of the said opposite end of said matching section, each respective said loop section being connected at one end to said opposite end of its matching section, a pair of transition sections each having cross-sectional area substantially equal to the cross-sectional area of said loop sections of uniform cross-sectional area, and a common section having a substantially flat and elongated cross-sectional area and coupled between the respective ends of said transition sections.
