Abstract

Secondo l'invenzione si realizza una pompa dosatrice di liquidi da collegare ad un contenitore comprendente: una camera cilindrica (13) ricevente liquido da erogare, un primo pistone (12) scorrevole all'interno di detta camera cilindrica, un secondo pistone (16) presente anch'esso all'interno di detta camera cilindrica presentante uno stelo guidato coassiale nella cavità del primo pistone e funzionante da elemento valvolare, mezzi valvolari di ritenuta (20), almeno un mezzo elastico (1, 6) tale da far tornare il pistone nella sua posizione di riposo ad erogazione avvenuta, caratterizzata dal fatto che detto mezzo elastico (1, 6) è un soffietto in materiale plastico realizzato per stampaggio ad iniezione ed avente la superficie laterale conformata a spirale. Secondo un'esecuzione la spirale è a profilo cilindrico e secondo un'altra esecuzione è a profilo conico.According to the invention, a liquid metering pump is made to be connected to a container comprising: a cylindrical chamber (13) receiving liquid to be dispensed, a first piston (12) sliding inside said cylindrical chamber, a second piston (16) also present inside said cylindrical chamber having a coaxial guided rod in the cavity of the first piston and functioning as a valve element, retaining valve means (20), at least an elastic means (1, 6) such as to return the piston in its rest position after delivery, characterized in that said elastic means (1, 6) is a plastic bellows made by injection molding and having the spiral-shaped side surface. According to one embodiment the spiral is cylindrical and according to another embodiment it is conical.
