Official abstract text for this publication.
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 said 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 ). It enables small dimensions compared to conventional devices.

1 . Device for dispensing substances that comprises: a chamber provided with a substance inlet ( 2 ) and outlet ( 3 ); a piston ( 4 ) located inside the chamber ( 1 ), the movement of which causes the exit of the substance to the outside of said chamber ( 1 ); and a motor ( 5 ) provided with an output shaft ( 6 ) that drives the movement 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 ) that is connected to said worm gear ( 7 ) and to said first transmission element ( 8 ), transmitting the rotation from said worm gear ( 7 ) to said first transmission element ( 8 ). 2 . Device for dispensing substances according to claim 1 , wherein said first transmission element ( 8 ) is connected to said piston ( 4 ) by a pin ( 10 ) of said first transmission element ( 8 ) that is housed in a groove ( 11 ) of said piston ( 4 ), the rotation of said first transmission element ( 8 ) causing the displacement of said pin ( 10 ) inside the groove ( 11 ) and the alternating linear movement of said piston ( 4 ). 3 . Device for dispensing substances according to claim 1 , wherein said piston ( 4 ) comprises a cylinder ( 12 ) in which are placed the substances for their exit from said chamber ( 1 ). 4 . Device for dispensing substances according to claim 1 , wherein said chamber ( 1 ) also comprises an inlet ( 13 ) of air from the outside and an air outlet ( 14 ). 5 . Device for dispensing substances according to claim 1 , wherein said first transmission element ( 8 ) is a disc comprising a toothed wheel ( 15 ) with its teeth located at the perimeter of one of the faces of the disc. 6 . Device for dispensing substances according to claim 1 , wherein said second transmission element ( 9 ) comprises a first toothed wheel ( 16 ) that engages said worm gear ( 7 ) and a second toothed wheel ( 17 ) that engages the first transmission element ( 8 ). 7 . Device for dispensing substances according to claim 6 , wherein the diameter of said first toothed wheel ( 16 ) of the second transmission element ( 9 ) is smaller than the diameter of said second toothed wheel ( 17 ) of the second transmission element ( 9 ). 8 . Device for dispensing substances according to claim 5 , wherein said second transmission element ( 9 ) comprises a first toothed wheel ( 16 ) that engages said worm gear ( 7 ) and a second toothed wheel ( 17 ) that engages the first transmission element ( 8 ); and wherein the toothed wheel ( 15 ) of the first transmission element ( 8 ) and the second toothed wheel ( 17 ) of the second transmission element ( 9 ) are perpendicular to each other. 9 . Device for dispensing substances according to claim 2 , wherein said piston ( 4 ) comprises a cylinder ( 12 ) in which are placed the substances for their exit from said chamber ( 1 ). 10 . Device for dispensing substances according to claim 2 , wherein said first transmission element ( 8 ) is a disc comprising a toothed wheel ( 15 ) with its teeth located at the perimeter of one of the faces of the disc.
