Beschreibung
Zusammenfassung:	The device comprises a chamber (1) provided with an inlet (2) and an outlet (3); a piston (4) inside the chamber (1), the movement of which causes the exit of the substance; and a motor (5) with an output shaft (6) that drives the motion of said piston (4) when it receives a signal from a sensor; and transmission means that transmit the drive movement from the motor (5) to said piston (4); characterised in that said transmission means comprise: a worm gear (7) rotationally attached to the output shaft (6) of the motor (5); a first transmission element (8) connected to said piston (4); and a second transmission element (9) connected to said worm gear (7) and to said first transmission element (8).The device enables small dimensions compared to conventional devices.
