1) A solenoid operated unit for detecting and bleeding an undesired liquid present with a desired liquid of a different resistivity and a different specific gravity, two liquids being immiscible with each other, the solenoid operated unit comprising of a solenoid, a static core, a plunger, at least one compression spring, characterized in that the solenoid operated unit has:
a. a pair of parallel sensor pins at a distance from each other such that an ohmic value of a resistance between them is less than a resistance R3 when the pair of parallel sensor pins is surrounded by the undesired liquid, and an ohmic value of a resistance between them is significantly higher than the resistance R3 when the pair of parallel sensor pins is surrounded by the desired liquid; b. a pair of serial sensor pins at a distance from each other such that an ohmic value of a resistance between them is less than the resistance R3 when the pair of serial sensor pins is surrounded by the undesired fluid, and an ohmic value of resistance between them is significantly higher than the resistance R3 when the pair of serial sensor pins is surrounded by the desired fluid; c. a vertical bleeding path, having an upper opening and a lower opening; d. an exit path connected and disconnected with the lower opening of the vertical bleeding path; e. a dual function diaphragm having an annular part, a nuclear part and a cap like construction on an other side of the nuclear part; f. a pressure equalization outlet; and g. a modular mechanical sensor assembly having a tunnel with a plurality of pressure equalizing openings all round its length and having a plurality of convex guides all along its length, and a spherical ball. |
