The invention relates to a method for feeding pasty masses using a pump device which has a piston pump with at least two cylinders with in each case one piston, in which pump device each cylinder is connected via an inlet opening, which can be closed by an inlet slide assigned thereto, to a pre-fill container, and in which pump device each cylinder is connected via an outlet opening, which can be closed by an outlet slide assigned thereto, to a feed line, - in which method pasty mass is fed from the pre-fill container into the respective cylinder during a suction stroke of a cylinder with the inlet opening open and the outlet opening closed and pasty mass is fed into the feed line during a pumping stroke of a cylinder with the outlet opening open and the inlet opening closed, in which method the piston speed is greater during the suction stroke than during the pumping stroke, in which method at the end, toward the end or shortly after the end of the suction stroke, the inlet opening is closed by the inlet slide and thereafter a compression of the pasty mass takes place in the cylinder before the outlet opening is opened. |
