Abstract: Apparatus and methods for dispensing small beads of a viscous, mixed fluid material formed by first and second viscous fluids. The apparatus includes first and second metering rods for moving in a reciprocating manner, such that the first metering rod extends into a first fluid passageway, and the second metering rod extends into a second fluid passageway. A mixing passage communicates with the first and second fluid passageways to receive the first and second viscous fluids from the first and second fluid passageways. A dispensing passageway is in fluid communication with the mixing passage, and dispenses a small bead of viscous, mixed fluid material formed by the mixed first and second viscous fluids. A control retracts the first and second metering rods to prevent drooling of the viscous, mixed fluid material from the dispensing passageway after a dispensing cycle.

Abstract: A high pressure homogenizer provided with head for the treatment of products with solids and fibers comprises a block defining a passage for the product from an intake area to a delivery area, a piston movable axially with reciprocating motion in the block to pump the product in said passage, intake and delivery valves positioned internally to the block and operatively active on said passage to open it/close as a function of a motion of the products in the passage. The passage is positioned in the block in position of non-interference with the motion of the piston and the intake and delivery valves have no springs and are operatively inserted in said passage in intermediate position between said intake and delivery areas, to favor the sliding of the products and to prevent the accumulation of substances that are sensitive to shear effects contained in the products themselves.

Abstract: The system comprises a first alternating pump (1) for injecting a dose of a first component (4) into a mixer (3) and a second alternating pump (2) for injecting a dose of a second component (5) into the mixer (3) sequentially relative to the first pump. The movement of the piston of each pump can be reversed from a direction of suction and expulsion of the pump to a direction of expulsion of the corresponding component, and vice versa. An injection valve (10, 11) is inserted between each pump (1, 2) and the mixer (3). The system also comprises a programmed controller (20) for initiating the movement of the piston of a pump in the direction of suction and expulsion of the volume of this pump after having determined, following the closing of the injection valve (10, 11), that the remaining volume in the pump (1, 2) is inadequate for injecting the following dose into the mixer (3).

Abstract: A shot pump including a cylinder standing upright and an inlet having a check valve which allows a paste-like transferred substance to only flow into the cylinder therethrough. The shot pump also includes an outlet having a check valve which allows the transferred substance to only flow out of the cylinder therethrough. Additionally, a piston is configured to vertically reciprocate in the cylinder, causing the transferred substance to be sucked from the inlet and then to be discharged from the outlet. The ratio of a clearance between a side face of the piston and an inner side face of the cylinder to an outside diameter of the piston is 1/50 to ½. The transferred substance is sucked from the inlet, is then caused to pass through the clearance between the side face of the piston and the inner side face of the cylinder, and is discharged from the outlet.

Use is made of individual conveyor pumps driven individually by hydraulic adjusting units in the form of double-acting hydraulic cylinders.

Abstract: A fluid mixture dispenser has a container with independent fluid chambers that respectively maintain fluid components for combination. Each chamber includes an outlet and a driver. For each chamber, actuation of the driver effects the discharge of the fluid component through its outlet. The outlets of the fluid chambers open into a second container to receive a fluid mixture consisting of the fluid components, where the second container also includes an outlet and a driver. Actuation of the driver for the second container effects the discharge of the fluid mixture.

Abstract: The invention provides a method and an assembly for the batch-wise preparation of a liquid product constituted by a mixture of at least one primary liquid and at least one secondary liquid. The secondary liquid and liquids, respectfully, to be meteredly added to the flowing primary liquid are displaced, before the metered addition, from a main reservoir to a buffer reservoir. Each of the secondary liquids is conveyed by means of an associated conveyor operating according to the displacement principle. The conveyors are hydraulically operated, whereby the same liquid can be used both as hydraulic operating medium and as primary liquid. A mixing element is provided for mixing the primary liquid with the secondary liquid or liquids. The primary liquid is under pressure, since it can be blended with carbon dioxide. The secondary liquid or liquids are supplied to the mixing element under a pressure that is higher than the pressure inherent to the primary liquid in the mixing element.
