Реферат: A device for feeding liquid under pressure comprises a vessel having an operating fluid inlet, an operating fluid outlet, an inlet opening for the liquid to be fed under pressure and an outlet opening for the liquid to be fed under pressure; a float disposed within said vessel; a change-over valve for alternately switching the operations of opening and closing the operating fluid inlet and outlet in response to the movement of the float; and a link mechanism. The link mechanism comprises a valve operating rod connected to the change-over valve and a compression spring supported at one end thereof by the valve operating rod and adapted not to cross any fulcrum at the time of operation thereof, and operates to move the valve operating rod in a snap motion in response to the movement of the float. The compression spring is supported by the valve operating rod so that the vector of action of the compression spring passes onto the point connecting the compression spring with the valve operating rod.
