Pump which can be actuated by a hand lever

Pump ( 4 ) which is actuable by a hand lever for spraying liquid ( 3 ), especially for placing on bottles ( 1 ) with a pump piston ( 13 ) which is linearly displacable in a pump chamber ( 17 ) on a housing side, against force of a compression spring, for spraying the liquid ( 3 ) out of a mouthpiece nozzle ( 24 ). the pump piston ( 13 ) being coupled to the pin-mounted hand lever ( 6 ) by a connecting pull member (G), the connecting pull member (G), extending from a rear side ( 49 ) of the pump piston ( 13 ), parallel to the displacement path of the pump piston in the direction of the mouthpiece nozzle ( 24 ), and a cross-piece ( 48 ) on the rear side ( 49 ) of the pump piston ( 13 ) as a carrier of the pump piston ( 13 ), forming a single element therewith, wherein bearing pin portions ( 6 ') of the hand lever ( 6 ) are hooked into open slits ( 9 ), loaded by compressive force of the compression spring ( 15 ) toward a slit end, and wherein an opening (Ö), which is partially surrounded by a frame-shaped the connecting pull member (G) in longitudinal direction of the pump, is pivotable on a hand lever side of a compressed the compression spring ( 15 ) over end ( 25 ) of a carrying tube ( 26 ) to be fitted with mouthpiece ( 23 ).
