Pump which can be actuated by means of a hand lever for spraying liquids

A hand-lever-actuable pump (4) for spraying liquid, in particular for mounting on bottles (1) and the like, comprising a pump piston (10) which is displacable linearly (line x—x) counter to force of a compression spring (12) in a pump chamber (9) in a housing and is intended for spraying the liquid (3) out of a mouthpiece nozzle (18), the pump piston (10) being coupled to a hand lever (6) via a connecting pull member (G) such that pivoting movement of the hand lever (6) pulls the pump piston (10) in direction of the liquid moving toward the mouthpiece nozzle (18), and furthermore, starting from a rear side (34) of the pump piston (10), the connecting pull member (G) extending parallel to pump-piston displacement path in direction of the mouthpiece nozzle (18), wherein on the rear side (34) of the pump piston (10) is a hook-in slot (35) which is located in direction of the pump-piston displacement path, is open in direction of compressive force of the compression spring (12) and is intended for a drive crosspiece (36) of the connecting pull member (G).
