Abstract:

A lubricant additive dispensing apparatus comprising a base providing a manifold distribution to present lubricant to a series of dispensing chambers. The dispensing chambers are fabricated having a porous sidewall formed in a tubular shape. Additive is stored within a reservoir formed by the tubular shape. A delivery piston is provided proximate and in fluid communication with the manifold. The lubricant applies pressure to the delivery piston. The delivery piston applies pressure to the stored additive. The pressure forces a small volume of additive to pass through the porous sidewall, blending the additive with the flowing lubricant. The reservoir can be formed between an outer tubular member and an inner tubular member. Lubricant can pass through an interior of the inner tubular member, exiting a flow discharge port located proximate an end cap assembled to a distal end of the reservoir.
