BATCHER AND DOSAGE DEVICE Russian patent published in 2020 - IPC G01F11/02 G01F11/08 

FIELD: batchers.

SUBSTANCE: present invention relates to a batcher with a specially made resilient valve providing reliable shutdown of the dispenser. Dispenser (I) for dispensing device for dispensing fluid medium comprises cover (10) ("dispenser base") with outlet (11) for fluid to be dispensed, wherein said cover has inner surface (12), resilient valve (20), geometric configuration (22) of which in at least some regions corresponds to inner surface (12) of cover (10), element 40 ("insert") having through hole (41) for fluid to be dispensed, through which possibility of supply of fluid medium between cover (10) and elastic valve (20) is provided due to deformation of resilient valve (20) and formation of intermediate space (10–20) between said elastic valve and said cover (activated state (B)), wherein cover (10) and said element (40) are connected by shape and friction fit, and elastic valve (20) is arranged there between. At that, when said dispenser is in initial state (A), elastic valve (20) is located on entire surface (12) with shape matching on inner surface (12) of cover (10), as a result of which hydraulic seal is provided between cover (10) and element (40).

EFFECT: technical result is provision of complete emptying and, at the same time, reliable closing of dispenser.
