Abstract
A flow sensor for sensing failure of flow of lubricant through a lubricant line, in which a piston is held away from a no-flow position against a spring by pressure of lubricant flowing in the line, the piston being moved by the spring to the no-flow position upon failure of flow thereby to signal the failure, and in which an adjustable bleed is provided to retard the movement of the piston to the no-flow position for signalling only upon a relatively prolonged failure of flow and not upon a relatively short cessation of flow.
