A fluid motion through the flow element is presented in the kind of an auto-oscillating system with the distributed parameters: mass, elasticity, viscosity. The system contains a self-excited oscillator and possesses a self-regulation on base of the intrinsic voluntary negative servo output feedback. The interaction dynamics of the submerged jet, out-flowing out of a flow element, with the homogeneous for it surrounding medium as well as dynamics of evolution of the spiral-vortex structures, appearing at the relative motion of fluids, are described for the first time. The conceptual model of a flow in the kind of the completed system of the cause and effect relationship, that presents the fluid motion process as a result in interaction of the motive power, applied from without, and the internal wave mechanism, self- regulating the flow structure and its intensity, is created.
