Abstract:
A device for initiating siphoning action to remove fluid from a fluid reservoir, comprising:a reservoir containing a fluid having at least a bottom section and side sections; an outlet tube connected to a fluid side of said reservoir and having an open first end and an open second end, said first open end located in a position to take suction from said bottom section of said reservoir; and an inlet check valve located inside said outlet tube adjacent said first open end, such that fluid can flow from said reservoir into said outlet tube; a siphon mechanism comprising a hollow tube with a suction portion having a length greater than a distance between said bottom section and a top extent of said side sections of said reservoir, a middle portion and a discharge portion having a length greater than said suction portion; and a discharge check valve located in said siphon mechanism, such that fluid can flow from the suction portion towards the discharge portion; and a flexible piston, attached to an outside surface of said siphon mechanism positioned at one end of said suction portion opposite said middle section; wherein an airtight seal is formed between the outlet tube and siphon mechanism when said suction potion of the siphon mechanism is inserted into said second open end of said outlet tube and further downward movement of the siphon mechanism initiates a siphoning action to draw fluid from said reservoir up the suction portion, through the middle portion and down said discharge portion expelling said fluid from the reservoir.
