摘要

The siphon (1) for especially tool machines has at least one curved pipe section (3,4) to which is connected an outlet pipe (6) which can be closed off by a solenoid valve (7). An additional shut-off element (16) also in the form of a solenoid valve is provided behind the curved pipe section (4) in the direction of flow, and during filling of the siphon is adjustable from a closed position to an open position. The additional shut-off valve is located in the drain pipe (12).
