ABSTRACT:
A piston-type point of lubrication magnetic flow indicator providing a barrel interfit with a bushing having a cylinder portion penetrating the barrel coaxially and a magnetic piston which reciprocates closely interfit inside the cylinder portion of the bushing. Lube oil enters an inlet port of the bushing, flows through a check valve into the cylinder portion, and impinges on one end of the magnetic piston. The impinging causes the magnetic piston to move in the cylinder portion uncovering at least one port formed through the cylinder portion which opens the cylinder portion to the barrel, directing flow thereto. The lubricating oil flows through the barrel and out of an aperture formed at a forward end of the barrel to a lubrication point. Movement of the magnetic piston through the cylinder portion triggers a magnetic reed switch mounted on an outside circumference of the barrel and generally overlying the relative axial position of the piston in the cylinder portion. The opening and closing of the reed switch can be electrically monitored by electronic lubrication monitoring systems or controls as are known.
