Abstract
A fluid container draining device for draining fluid from a fluid container, an oil filter, in a controlled manner. The fluid container draining device has a threaded screw with a sharpened tip and a channel communicating between an opening at a forward end of the screw and a rear region of the threaded screw. When the screw is turned it will penetrate the wall of the fluid container and enter the fluid containing cavity of the fluid container. The threaded screw has a radially extending abutment surface to provide fluid tight sealing between the screw and the fluid container's walls to prevent fluid leakage. A fluid valve is positioned at the rear region of the screw to provide fluid flow control between the interior of the fluid container and outside the fluid container. The fluid valve is provided with a fitting for connection to a suction line to thereby permit fluid to be evacuated from the fluid container.
