High pressure cleaning appts. - has pump supplying liq. to spray gun also powering generator charging battery for control members

摘要

A pump supplies a cleaning fluid at high pressure to a spray gun via a high pressure line. The electrically operated pump control is activated via operating elements at the spray gun powered by a sec. cell battery (13). The spray gun has a generator (7,9,10) providing the battery charging voltage which is driven by the high pressure fluid. Pref. the generator is driven by a rotor (6) rotated by the high pressure fluid fed through a sleeve (1) concentric to the rotor. ADVANTAGE - Uses flow energy of high pressure cleaning fluid to recharge operating battery.
