Abstract: A manually operated pump (1) for dispensing a fluid substance in which the movable element (16) of the delivery valve has an at least partially conical surface adapted to be coupled with a corresponding surface of a seat of the delivery valve, in a manner so as to be fit therein due to the action of the spring (10) that loads the movable element (16).

Abstract: A flat pump for producing liquid spray or for producing an atomized liquid stream may have a thickness of 6 millimeters or less. The flat pump may include an internal reservoir, a valve, a valve conduit and a vortex chamber wherein fluid from the reservoir may be pumped through the valve, along the valve conduit, and into the vortex chamber. An atomized liquid stream, spray, or mist formed in the vortex chamber may be expelled from the flat pump.

Abstract: A simplified pump for dispensing fluid substances withdrawn from a container of said substances, comprising a cup-shaped body into which a hollow stem extends, an endpiece of the cup-shaped body, said cup-shaped body presenting a passage, closable by a valve, and a seat for housing one end of a dip tube, a piston, an elastic member and a movable valve for closing the stem cavity, an elongated rod, a first end of which is inserted into and retained in a seat provided at the second end of the cup-shaped body, an intermediate portion of the rod having a cylindrical profile of diameter less than the diameter of the stem cavity into which said rod portion extends, said movable valve for closing the stem cavity comprising a continuous elastic lip projecting from a second end of the rod towards the outside of said cylindrical chamber, said lip being sealedly slidable in contact with the cylindrical surface of the stem cavity.

Abstract: A flat pump for producing liquid spray or for producing an atomized liquid stream may have a thickness of 6 millimeters or less. The flat pump may include an internal reservoir (3), a valve (19), a valve conduit (45) and a vortex chamber (49) wherein fluid from the reservoir may be pumped through the valve, along the valve conduit, and into the vortex chamber. An atomized liquid stream, spray, or mist formed in the vortex chamber may be expelled from the flat pump.

Abstract: A closable dispensing pump for fluid substances comprising a chamber in which a piston is slidable, drivable by a stem, said stem presenting in its interior at least one first passage communicating with said compression chamber and a dispensing pushbutton presenting a second passage opening towards the outside of said dispensing pushbutton. The first passage presents a first aperture which opens onto said first contacting surface, said second passage presenting a second aperture which opens onto said second contacting surface, said pushbutton and said stem being mutually rotatable about a longitudinal axis between at least one open position in which said first and second aperture face each other and are in mutual communication, and a closed position in which they are mutually isolated and displaced.

Abstract: An operating pushbutton for dispensing pumps for fluid substances contained in containers on which the pumps are mounted. The pushbutton has an end portion which can translate on a portion thereof applicable to the pump stem, such that when a pressure is exerted on said end portion it undergoes a free translation before causing the other pushbutton portion to move, hence preventing accidental dispensing of the fluid substance.

Abstract: A pushbutton for a pump or valve for dispensing fluid substances contained in a container on which the pump is mounted. The main portion of the pushbutton has a substance dispensing nozzle and elements for securely retaining said main portion on the pump or on a body rigid therewith. The pushbutton also has an upper or movable portion with a seat for sealedly housing the free end of the pump stem. The two pushbutton portions can translate one relative to the other and are connected together by tubular appendices which are inserted into and sealedly translatable one within the cavity of the other and are connected to said stem seat and to said nozzle respectively.

Abstract: Manually operated invertible pump for dispensing atomized liquids, the pump having a very compact structure and an aperture which can be intercepted by the pump piston to control liquid entry into the pump when this is in a downwardly inverted position.

Abstract: Manually operable pump for dispensing atomized liquids, the pump having passageways enabling air to enter the container on which the pump is mounted, when a vacuum forms in the container on dispensing liquid through the pump.
