Abstract

The invention relates to a pump for automatic and slow drainage of a vial containing a solution, preferably a medical solution. The pump comprises a closed pump housing (2), in which a pumping liquid (40) is arranged to flow through a throttle valve (42) provided between a first (36) and a second chamber (38) in the pump housing (2). The first chamber (36) is restricted by one side of a pump piston (22), which is displaceable in a piston cylinder (20), the pump piston for the output of the solution being driven by a vacuum in the piston cylinder (20) prevalent on the other side of the pump piston (22).
