Abstract

The metering pump dispenser serves for simultaneous metered output of liquid and/or pasty media from at least two separate supply chambers (18, 19), which are arranged in a common pump housing (2) and to which are assigned individual separate metering pumps (5, 6), each with an intake and output valve (23, 24). The metering pumps are manually driven by a common actuating device (3), which extends on the side of actuation in a common front side of the metering pumps (5, 6) that are present and is provided with one or more output channels (57, 58). Metering pumps (5, 6) each have as pump devices communication bellows (21, 22) which are joined on the housing side with pump housing (2) and on the output side with the common actuating device (3). Actuating device (3) is a lever-type device mounted in a swiveling manner around a swivel seat (11) on one side in a head part (10) of pump housing (2) axially projecting over supply containers (18, 19), for conducting limited pump strokes. Swivel axis (11') of swivel seat (11) is arranged crosswise to a common plane of symmetry (20) of metering pumps (5, 6), so that metering pumps (5, 6) have variable distances and variably large actuation levers to the swivel axis (11'), and upon actuation of actuating device (3), pump strokes of different magnitude can be introduced in a specific, preselectable ratio at the same time and in the same direction.
