Abstract
The partial vacuum generated in a vacuum chamber by a suction pump via an air aspirating line and a hose can be changed by admitting leakage air through an air supply line. The supplied amount of leakage air is determined by a relative movement of a regulating groove and a leakage groove in respect to each other, and the partial vacuum in the vacuum chamber is regulated in this way. Since in a breast pump the partial vacuum generated in the vacuum chamber is transmitted to the funnel-shaped breast body, it is possible in this way to also regulate the partial aspiration vacuum over the breast.
