Abstract
Apparatus for preventing damage to a machine in the event the machine inadvertently goes into reverse rotation. An automatically actuated flow controller is adapted to reroute the flow of lubricant to the primary pump when the machine rotates in a reverse direction thereby assuring that lubricant is supplied to the machine bearings, and the like, to prevent the machine from being damaged. The mechanism also has the ability to deliver a metered amount of lubricant to the main pump from an auxiliary pump to prime the main pump when the main pump is shut down thus allowing the main pump to be quickly brought on-line.
