FIELD: electrical engineering.
SUBSTANCE: proposed device has rigid framework accommodating sealed pump; the latter accommodates contactless permanent-magnet synchronous generator that has stator and permanent-magnet rotor, partition with holes receiving pressure valves, compression springs, rectifier-battery unit. Rotor shaft is hollow structure with blades in inner space and pressure valve at end. Rectifier-battery unit is connected to contactless synchronous generator and to universal plug connector by means of conductors.
EFFECT: enhanced efficiency, reduced mass, size and noise, enlarged functional capabilities.
