PCT No. PCT/EP91/01688 Sec. 371 Date Mar. 2, 1993 Sec. 102(e) Date Mar. 2, 1993 PCT Filed Sep. 5, 1991 PCT Pub. No. WO92/04128 PCT Pub. Date Mar. 19, 1992.A hand lever-actuated spray pump (1) having a pump chamber (4) which has an inlet (7) and an outlet valve (8), furthermore having a (sprung) pump piston (6) which interacts with a pump cylinder (5), a lever-like actuating handle (2) and an antechamber (20) which is connected to the pump cylinder (5), is arranged upstream of the pump cylinder (5) and into which there opens a suction tube (22); to achieve a practical and simple solution, it is proposed that the pump piston (6), the pump cylinder (5) and the antechamber (20) are arranged in axial extension of the outlet nozzle (13) and are supported in the pump head, the pump piston (6) being held captive in the fixed outlet nozzle (13), the suction tube (22) opening approximately at right angles into the antechamber (20) and the spring (35) acting directly on the hand lever (10).
