A piston (46) is positioned inside the chamber (30) and is movable to vary the volume of the chamber (30), for example between a first position defining a maximum chamber volume and a second position defining a minimum chamber volume.

A tool, container and method for extracting a liquid; the tool for extracting a liquid comprises: a pressure-changing means, a liquid-reservoir space, a liquid-drawing channel and an outflow channel; the pressure-changing means comprises a cylinder and a piston capable of moving back and forth in the cylinder; the back-and-forth movement of the piston causes positive and negative pressure changes in the cylinder; a start end of the liquid-reservoir space is in communication with the inside of the cylinder; a temporary liquid-storage groove or an opening is provided on a wall of the cylinder at a horizontal position below a port of the start end of the liquid-reservoir space; the volume of the maximum sealing portion of the cylinder is greater than the volume of the liquid-reservoir space; the liquid-drawing channel communicates with the liquid-reservoir space; the outflow channel communicates with a tail end of the liquid-reservoir space.

The invention relates to a device for dosing into a container (2) a pasty food product including solid pieces and a sauce. The device comprises an metering nozzle (1) comprising a main outlet to which the pasty food product with solid pieces is provided by a first channel (13) of the nozzle (1), and at least two peripheral outlets situated at a periphery of the main outlet to which the sauce is provided by corresponding second channels (14). The device comprises a support (3) for holding a container (2) to be filled from the nozzle (1), and is configured so that the metering nozzle moves, relative to the support (3), following a path around a central axis of said support. A corresponding system and a method are also provided.

A dispensing system for dispensing a precise or controlled volume of fluid to a downstream assembly of an appliance is provided. As one example, the downstream assembly may be an ice making assembly and the appliance may be refrigerator appliance. In one example aspect, a dispensing system includes a housing that defines a chamber. A piston is movable within the chamber. The dispensing system also includes a plurality of valves that may be moved between various positions to move the piston between various positions. When the piston is moved within the chamber, the piston displaces a precise or controlled volume to the downstream assembly.

The invention relates to a proportional volumetric doser (10) comprising a motor (20) to which a pump (30) is connected, which pump (30) comprises a tubular sleeve (80) inside which a cylinder (85) is housed in which a small doser piston (62) slides, mechanically connected to an output shaft of the motor (20), wherein an inner surface of the cylinder (85) and the small piston (62) partially define a dosing chamber (48) of an auxiliary fluid to be mixed in the motor (20) in a prefixed amount with the main fluid, where said cylinder (85) has a threaded outer portion that meshes with a threaded portion of a ring nut (70) so that a rotation of the ring nut (70) causes an axial translation of the cylinder (85) and the variation of the volume of the dosing chamber (48), said proportional volumetric doser (30) being characterized in that the sleeve (80) comprises a locking system (100) configured to mechanically lock the cylinder (85) with respect to the tubular sleeve (80) by creating a shape constraint.

An initial positioning system and method for liquid measuring and taking. The system comprises a measuring passage, a variable pressure chamber, and a piston, an initial end of the measuring passage being in communication with the upper part of the variable pressure chamber; the piston reciprocates in the variable pressure chamber to cause a change between positive pressure and negative pressure in the variable pressure chamber; the initial positioning system further comprises a pressure relief port located on the wall of the variable pressure chamber and capable of communicating with the outside of the variable pressure chamber; when the piston is located at the pressure relief port, and the inside and outside of the variable pressure chamber are in communication, the maximum volume of the liquid that can be accommodated in the variable pressure chamber is not smaller than one third of the total volume of the variable pressure chamber.
