Abstract
A liquid is dispensed to a receiving surface by feeding the liquid under pressure to a dispensing orifice surrounded circumferentially by a convex toroidal boundary surface which is non-wettable by the liquid to form a liquid droplet perimetrically contacting the toroidal boundary surface in a manner which resists lateral displacement of the droplet relative to the orifice, and effecting relative movement of the receiving surface past and in wiping contact with the droplet to transfer liquid from the droplet to the receiving surface while regulating the delivery rate of liquid to the orifice to maintain the droplet. The invention is described in the context of roller bearing lubrication.
