ABSTRACT:
A permanently installed lubrication system supplies grease under constant pressure to bearings, or other mechanism at near or remote locations, by means of constant spring tension rather than conventional coil spring expansion on a piston, or plunger, head. Influent and effluent fluid conduit connections into the piston head cylinder permit absolute or differential pressures from about 26 to about 185 pounds per square inch. A pair of back to back constant pressure, coiled band springs exert constant tension and are supported between a pair of T-shaped plates affixed to one end of an elongated, hollow tubular housing.
