ABSTRACT:
An oil drain valve consisting of a drain fitting and a removable actuator. The drain fitting is substantially the size and shape of a standard oil, is axially hollowed, and is perforated in the walls thereof to form a passageway to drain oil from the oil pan. The passageway contains a spring-loaded ball valve. The drain fitting is internally threaded on its bolt end to accommodate the external threads of the actuator. A mechanically advantaged lever is positioned within the actuator such that tightening and loosening of the actuator within the drain fitting causes the opening and shutting of the ball valve. The actuator may be fitted to a hose and optional pump for disposal of the oil. A protective cap is mounted within the head end of the drain fitting when the fitting is not in use.
