BUTTON MECHANISM FOR CONTROLLING FEED VALVE WITH MULTIPLE DOSING Russian patent published in 2014 - IPC G05G1/02 

FIELD: physics; control.

SUBSTANCE: invention relates to a button mechanism for controlling feed valves with multiple dosing. The button mechanism has a lower part (1) and a cover (2), connected to each other to form a housing. The cover (2) is in contact with a pusher (3), which passes through an opening (5) in the lower part (1) and protrudes from the lower part. There is a pressure-bearing surface on the cover (2). A spring (4), located between the cover (2) and the lower part (1), provides mechanical displacement in the initial position of the button mechanism. The cover (2) is adapted to move from its initial position and approach the lower part (1) in response to an external pressing force. The cover (2) is in form of a single component and is connected to the lower part (1) such the cover (2) can move into a position which is inclined relative to the initial position, wherein the angular position of the cover (2) and, consequently, the length of that portion of the displaced pusher (3), which protrudes from the lower part (1), depends on the point of application of the force on the pressure-bearing surface due to change in the axis of rotation of the cover.

EFFECT: high efficiency of dosing liquid in multiple different amounts.
