Abstract

The invention provides a metering pump having pistons (13, 13') which lie opposite one another, are guided in cylinders (11, 11') and are connected to one another by a slide (14) which is moved in a reciprocating manner by a drive motor (201), a switching device (3) being arranged between the pistons (13, 13') in a valve block (2), which switching device alternately connects the opposite cylinder spaces to a suction opening (4) and a delivery opening (5).
