Patent ID: 7461670

Claim:
A cycle indicator for use with a divider block in a high pressure, low volume lubricant distribution system, the divider block having a piston bore and a reciprocating piston, the reciprocating piston dispensing a quantity of lubricant during each reciprocation cycle, the cycle indicator comprising: a housing having an internal cavity, the cavity communicating to the piston bore of the divider block; a piston follower contacting the piston within the piston bore and extending into the cavity; a spring biasing the piston follower against the reciprocating piston so that the piston follower follows the motion of the piston as it reciprocates and dispenses lubricant; an internal magnet within the cavity and following the motion of the piston follower; and an external annular indicator following the motion of the internal magnet, which follows the motion of the piston follower, which follows the motion of the piston, the external indicator providing a visual indication of the piston motion, in which the external indicator is an external magnet and in which the external magnet includes radially oriented magnetic poles.
