ABSTRACT:
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).
