Abstract: This invention aims at providing a portable type of automobile engine oil suction pump which features a simple construction and a luminous indication lamp to warn its users of the exhaustion of the engine oil. This invention provides the improved structure of a portable type of automobile engine oil suction pump. Its main features are: an inner gear set comprising an inner ring gear and a pinion gear in the interior of two circular disks; and, an eccentric, convex, crescent-shaped block having an inner concave edge in touch with the pinion, and located eccentric to the ring gear with its convex side jointly set with the pinion to form an outer peripheral shape so as to enable one side of the inner ring gear to be engaged by the pinion, and the other side to keep in touch with the convex face of the eccentric crescent block, so as to allow the inner pinion to directly join with the revolving shaft of the motor to cause the ring gear to rotate.

Abstract: This invention relates to an automobile grease suction machine, particularly denoting a portable automobile grease suction machine assembled by a sealed type of motor which uses the motor car's own battery as its power source, a sealed type of gear pump box, a rotating shaft connecting link, a suction joint, a suction tube and a lubricant discharger. The presentation of a structure of a simplified vacuum oil suction machine featured for a diminished volume, convenient for application and conveyance and being free from the limitation of the place and time of application are regarded as its objects.
