Abstract:
A single-use aerosol dispenser holding motor oil under pressure, said dispenser including:(a) a sealed pressurized canister having an outlet and no inlet, said canister having said motor oil contained in an interior cavity formed within said canister and said canister being internally pressurized substantially above atmospheric pressure by a substantially non-flammable propellant;(b) coupling means for transporting said motor oil to the interior of an engine, said coupling means adapted for sealingly connecting said outlet to an oil passageway of the engine;(c) valve means, interposed between said coupling means and said canister, for selectively placing said coupling means in communication with the interior of said canister, said valve means being mechanically finger-operated in response to manual depression thereof for selectively passing said motor oil from within said canister to said coupling means;(d) a tube located in said interior cavity of said canister extending from said outlet to a region within the interior of said canister remote from said outlet so as to place said region in communication with said outlet through said tube;(e) a hose having a first end and a second end and a first passageway therethrough, said first end of said hose being in communication with said valve means through said passageway;(f) threaded fitting means attached to said second end of said hose and adapted for threadingly sealing said second end of said hose to the oil passageway of the engine, said threaded fitting means having a second passageway therethrough in communication with said first passageway of said hose and, when said threaded fitting means threadedly seals said second end of said hose to the oil passageway of the engine, said second passageway being in communication with the oil passageway of the engine; and(g) threaded adapter means, threadedly receiving said threaded fitting means, for threadedly sealing said threaded fitting means to the oil passageway of the engine, said threaded adapter means having a different threaded outer diameter than said threaded fitting means, said threaded adapter means including a plurality of adapters, each adapter of said plurality of adapters having a different threaded outer diameter from each other adapter of said plurality of adapters.
