Abstract (en)
[origin: DE19727485A1] The invention relates to a device for placing a liquid con a substrate. The inventive device comprises a housing (2) with a liquid receptacle (52), an applicator (30) protruding from the housing, a pump chamber (54) which is connected to the liquid receptacle via a first valve (21) which opens when there is an underpressure in the pump chamber and which is connected to the applicator via a second valve (29), in addition to an actuator (44; 56) with which the volume of the pump chamber can be reduced counter to the force of a spring device (40; 58; 84), wherein the second valve opens in the direction of a reduction in the pump chamber when an actuating element is operated. The invention is characterized in that the valve openings (12, 26; 74, 76) of the first and second valve are arranged on separating walls (4, 6; 66, 68) rigidly connected to the housing, in that the second valve (29; 89) is opened by an overpressure in the pump chamber (54; 82) and in that the wall of the pump chamber (54; 82) is hermetically sealed outwards with the exception of the valves (21, 29; 87, 89).
