Abstract. The modeling of shutter dynamics of a blow back valve is described with the systems of differential equations with variable structure and impulses in the present paper. The changes of the right-hand side of the system and impulsive perturbations take place at the moments when the so called ``shifting functions'' cancel (become zero). The structure of the modeling system changes depending on the states ``closed'' and ``open'' of the shutter valve. The impulses reflect the instantaneous change of the shutter valve speed during the switching from open to close position and intermittent shifting of the shutter valve. The main result in this paper is finding the suitable conditions which ensure the continuous dependence of the modeling system regarding the changes of the initial condition and switching functions.
