A manually operated pump () for dispensing a fluid substance in which the movable element () 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 () that loads the movable element ().

Hand held dispenser

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.

Flat atomizer pump

A simplified pump for dispensing fluid substances withdrawn from a container of said substances, comprising a cup-shaped body into which a hollow stem extends, an endpiece of the cup-shaped body, said cup-shaped body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.

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.

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.

Simplified invertible pump for dispensing atomized liquids

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.

Invertible pump with air passageways, for dispensing atomized liquids

Manually operable invertible pump for dispensing atomized liquids, the pump having a very compact structure and a flexible diaphragm valve for controlling liquid entry into the pump when this is in an inverted or partly inverted position.

Manually operable invertible pump for dispensing atomized liquids

A manually operable dispensing pump for application to liquid containers, in which the pump has a hollow stem which projects from a hole provided in a flange forming part of the pump, the stem having a profiled annular part which seals against a profiled seat on the flange when the pump is in its rest state, there projecting all about said flange seat a skirt within which the annular part of the stem slides and seals.

Dispensing pump with improved sealing for application to liquid containers

A pump for manually dispensing liquids under pressure, including a cup-shaped body, and a stem a piston portion of which defines a compression chamber closed at one end by a valve formed from a ball movable on a seat in a hollow appendix in the interior of a body, and closed at the other end by a valving element movable within a stem bore and having a conical part which can seal against a conical seat in the stem, the pump having a width greater than and a length less than known pumps of equal delivery capacity.
