Abstract

Abstract An oil change apparatus for use in changing the motor oil in a motor vehicle includes a key-operated drain valve removably mounted within a lockable protective housing and a flexible line connecting the drain valve with the engine oil pan of the motor vehicle. An oil filter relocation flange and bracket accessibly mounted within the engine compartment and coupled via oil lines to the original engine block receptacle for the oil filter serves to relocate the engine oil filter to a position that provides easy access. A power assisted oil change apparatus includes an electrical pump and electromechanical valve conveniently mounted within the engine compartment of the motor vehicle for pumping used motor oil from the engine oil pan into a disposable container at oil change times.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 178 words
Power assisted oil change apparatus for use in changing the motor oil in a motor vehicle, the apparatus comprising: electrical pump means coupled to an engine oil pan of said motor vehicle for pumping used motor oil from the engine oil pan, said electrical pump means including integral motor driving means and being mounted at a point on said motor vehicle that is higher than said engine oil pan; electromechanical valve means coupled to a discharge port of said electrical pump means, said electromechanical valve means including an outlet port and being mounted at a point on said motor vehicle that is higher than said engine oil pan; switch means coupled to a battery of the motor vehicle and to said electrical pump means and electromechanical valve means for simultaneously applying battery voltage to said electrical pump means and electromechanical valve means to initiate a flow of oil from said engine oil pan; and a disposable container coupled to the outlet port of said electromechanical valve means for receiving the motor oil pumped from the engine oil pan.
