摘要:
Devices for dispensing well-controlled unit portions of liquid sweeteners. The devices incorporate structure for accurately and precisely dispensing small volumes of concentrated sweeteners in liquid form. The devices are of compact size and, therefore, are conveniently portable by a consumer. Methods for dispensing liquid sweeteners are also disclosed.

Systems and methods for hydraulically and volumetrically filling and dispensing target fluid. A hydraulic system comprises an actuator (12), a hydraulic coupler (14) that includes substantially incompressible hydraulic liquid (38), and a target fluid container (16). The actuator includes a motor (60) or driver, such as a step motor, linear actuator, servomotor, pneumatic motor, or other similar device, to selectively drive a piston (30) of the hydraulic coupler. The coupler includes a conduit (19), column, shaft or other leak proof assembly that acts as a conduit for the substantially incompressible hydraulic liquid and includes a cord (174) and a piston (34), which is selectively pushed by the incompressible hydraulic liquid, thereby driving a plunger to selectively press against a slidable wall of the target fluid container, causing the target fluid to be dispensed therefrom, or retract the plunger from the container, pulling the slidable wall therewith through the use of a vacuum selectively created between the plunger and the wall.

The present invention relates to a dispensing apparatus (1) comprising a housing (3) and a metering tube (7). The metering tube (7) has an opening (17) to the interior thereof and the housing (3) has a chamber (4) therein for storing medicament. The metering tube (7) is extendable to a dispensing position, and retractable to a filling position. The opening (17) is in communication with the chamber (4) when the metering tube is in the filling position. The invention further relates to a method of operating dispensing apparatus.

Eine Dosiervorrichtung mit einem ortsfesten Grundkörper (2) sowie mit einem an dem Grundkörper (2) verdrehgesichert und hubbeweglich gelagerten Betätigungselement (1), sowie mit einer Zähleinrichtung für die Betätigungshübe, die einen abhängig von einer Hubbewegung des Betätigungselementes zwangsgekoppelt drehbaren Zählring (7) aufweist, und mit wenigstens einem Sperrmittel (16,17) zum Blockieren des Betätigungselementes (1) nach einer vorgegebenen Anzahl von Betätigungshüben ist bekannt. Erfindungsgemäß ist das wenigstens eine Sperrmittel (16,17) dem Zählring (7) derart zugeordnet, dass der Zählring mehr als eine volle Umdrehung durchführen kann, bevor das Betätigungselement (1) blockiert wird. Einsatz für die Dosierung zerstäubbarer Medien.

The invention relates to a volumetric metering valve for liquid and viscous substances, comprising a valve body (10) and a valve cylinder (12) in which a piston is displaceably mounted. A driving piston (14) which is in fluid communication with a driving medium and which is displaceable in the valve cylinder (14) actuates a metering piston (16) that is connected to the driving piston, the path of movement of the driving piston (14) and/or the metering piston (16) in the valve cylinder (12) being delimited by a movable stop (18).

The present invention relates to a volumetric metering device for fluid products comprising: an adjustable-volume metering chamber (4) operationally associated with shut-off means (8) designed to connect said chamber to a reservoir (5) containing the fluid product to be metered and to an outlet port (2). Actuator means (10) are also provided, being able to move a piston (9) arranged in a sealingly slidable manner inside the metering chamber (4) so as to perform an intake stroke, during which a measured quantity of alimentary fluid is introduced inside the metering chamber (4), and a compression stroke, during which the alimentary fluid contained inside said metering chamber (4) flows out through the outlet port (2). The metering chamber (4) is provided with a rear chamber (11) capable of receiving the piston (9) during a step involving washing of the metering device (1). For this purpose, the piston (9) is moved by actuator means (10) along an additional over-travel section forming an extension of its intake stroke. The rear chamber (11) may in turn be connected by means of at least one connection point (12) to an automatic flushing plant so as to cause circulation of a flushing fluid through the shut-off means (8) and the metering chamber (4). Advantageously, an injector (14) which is connected to the automatic flushing plant is mounted on the reservoir (5).

The present invention refers to a liquid dispenser comprising a valve block (1) that can be attached onto a vessel or which can be connected to a reservoir, said valve block including an intake valve (2), a supplying and dosing cylinder (3) in which a supplying and dosing plunger (4), connectable to an operating means (5), is slidably accommodated, and comprising an outlet means (6) for the liquid connectable to the valve block (1). According to the invention, the valve block (1) and the supplying or dosing cylinder (3) form an integral unit.
