Abstract: Disclosed is a metering pump comprising a housing that extends from an inlet region to an outlet and surrounds a piston which is urged into a starting position by a compression spring. In the metering pump the stop limiting the lifting stroke of the piston is formed by the lower end of the piston coming in contact with the inlet portion.
