摘要

Device for evacuation of liquids in containers with difficult access, which being applicable in those containers that need to be emptied at a certain frequency, and are located in hard to reach places, such as those that constitute the crankcase of an automobile engine and the device being provided in question to be mounted inside such container, being immersed in the liquid contained therein, essentially characterized in that it is formed from a main hollow cylindrical body whose lower base has a central hole and one outer wing for fixing to the outer face of the container bottom in which is applied, leaving said main cylindrical body except for its said base inside said container; It is having foreseen that axial and concentrically to this cylindrical body go mounted a hollow body authorized displacement, axial inside one, and whose inner hollow body inferiorly has an outer wing or base on which is mounted surround forms a resilient element intended to close and / or open, according to its position, a plurality of lateral holes provided in the cylindrical main body, formed in proximity to its base, and adapted to close and / or also open the central opening of the base or bottom such main body, going housed in said concentric body a lower threaded shank thereto and a stem portion overlapping the above, the stem portion is secured to a steel cable manual traction, which emerges when, outside and is protected a casing cover; exist between the inner side surface of the main cylindrical body and the outer lateral surface concentric body, a new body as inverted and defined by two concentric walls joined superiorly channel whose channel-shaped body constitutes the positioning means of a spring pushing the closed position to the concentric body; and with the particularity that the assembly is sealed by a screw cap on the upper part or section of the main cylindrical body, and through which is pulled through the cable.
