Abstract
In a series progressive divider valve having a number of identical valve units disposed adjacent to each other, each formed by a base member and a spool member having a movable spool therein, a manifold in the form of a plate which can be inserted between the base member and the spool member of a valve unit which modifies the flow of lubricant in the event one of the output ports becomes blocked or restricted. In the event such a blockage or restriction occurs, a relief valve disposed in the manifold plate is opened which establishes communication between two normally non-communicating bores which results in the re-routing of the lubricant to the succeeding valve unit. The manifold permits the overall output/lubricant delivery configuration of the divider valve to be continued in the event of such a blockage or restriction. The manifold may also be incorporated into the base or feeder unit as opposed to a separate plate and, in such an embodiment, the relief valve may be disposed in either the base unit or the feeder unit.
