Title: Hand-operated pump with a trigger, for dispensing liquids

Abstract: A pump for dispensing liquids includes a hollow cylindrical support body having an annular channel formed at a first axial end of the body and open towards the internal cavity of the body. A pumping member in the form of a resiliently-flexible, cup-shaped diaphragm has its cavity facing the annular channel. A lever is pivoted about a pin carried by the hollow cylindrical body and includes a first end that engages the cup-shaped diaphragm of the pumping member for collapsing the diaphragm when it is desired to dispense liquid. A tubular element extends through the cup-shaped diaphragm of the pumping member and guides the axial movement of the pumping member.
