ABSTRACT:
A device that relieves lubricant pressure in a divider block lubrication system into a fluid reservoir, a container, or directly back into the compressor frame to which the tubing is connected. This eliminates housekeeping, environmental, safety, and compressor component failure concerns associated with current atmospheric rupture assemblies that relieve directly to the atmosphere. The environmental compressor protection assembly contains a spring set to a pre-determined pressure. Lubricant pressure in excess of this pre-determined set pressure results in spring compression and opening of a relief path. The assembly preferably remains in a full open position and must be must be manually reset to the closed position to prevent fluid flow in the system. The relief path can lead to a fluid reservoir, a container, or directly back into the compressor frame. Flow of lubricant through the relief path results in loss of flow to the lubrication system. This triggers an alarm in the no-flow system and shutdown of the compressor. The relief path remains open until an operator resets the device. A visual indicator shows an operator if the relief valve is open or closed.
