DISPENSER Russian patent published in 2019 - IPC B05B11/00 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to a dosing device with a pump device and can be used for dosing any fluid substances, in particular, liquid, gel-like or paste-like media for use in hospitals and other similar facilities. Dispensing device (1) has pump device (2) comprising actuator (5) with outlet opening (12). Actuator (5) is movable relative to bearing element (6) connected to housing (7) of pump without possibility of rotation in working position. Actuator (5) is installed with possibility of rotation relative to bearing element (6). Bearing element (6) comprises at least one protruding jumper (25) with upper thrust edge (24). Along circumference of inner surface of section (5') of actuator (5) having, in fact, a pipe shape, at least two ledges (22, 22', 22''), which determine a different displacement stroke. Each of steps, depending on rotary position of actuator (5), in lower position of displacement rests against stop edge (24).

EFFECT: simplified design and increased reliability of dosing volume control.
