Portable, battery operated air pump

摘要: A mechanically simply battery operated air pump for one hand operation comprises a (1), motor (2), gear (3), cylinder/piston (4), and nozzle (5). The battery, the motor, gear, are arranged end to in order provide structure tapering against (3) is constituted by pinion (10) rotating around an axis (11) extending parallel longitudinal (12) of whereas driven wheel (13) rotates (15) perpendicular pump. (4) connecting rod movement with rotation (24) being (10). (5) concentric (15), accordingly, it may be fastened directly on said cylinder (21). (2) drives through whereby piston (20) displaced (21) establish overpressure within Preferably, intended bicycles, however, could also used other purposes.
