FIELD: drive atomizers. SUBSTANCE: compressor drive includes supercharging unit, piston located in pressure chamber and dividing it into first compartment measuring volume of fluid material and second compartment, valve unit coupled to supercharging unit. Valve unit is mounted for selective opening and shutting of egress of fluid material from inlet and for filling of first compartment of pressure chamber when outlet is shut and for feed of fixed volume of fluid material from first compartment through outlet when outlet is open. Piston is mounted for pushing of fixed volume of fluid material through valve unit by pressure exerted on piston by fluid material under pressure. EFFECT: simplified design of compressor drive and of control over it, possibility of preliminary adjustment of volume of supercharged fluid material. 18 cl, 16 dwg
