Patent ID: 8555927

Claim:
A divider block assembly for distributing a low volume of a lubricant at high pressure, the divider block being operated by the pressure of the lubricant being dispensed, comprising: a base plate comprising a plurality of removable sections including an inlet section, an end section, and one or more intermediate base sections, each intermediate base section including a lubricant outlet, the base plate being assembled from the plurality of removable sections using one or more fasteners; one or more divider block sections mounted on the one or more intermediate base sections, each divider block section having a top divider block surface and a piston bore, the piston bore having a top piston bore portion at a first depth from the top of the divider block, the piston bore for receiving a piston, a piston, and an outlet passage for lubricant dispensed by the piston as it is moved by the pressure of the incoming fluid, each divider block section having multiple counterbored mounting holes completely contained in the corresponding divider block section for receiving a fastener, each of the counterbored mounting holes having a shoulder positioned at a second depth below the top surface of the divider block, the second depth greater than the first depth, wherein the position of the shoulder reduces the distortion of the piston bore by reducing the compressive force on the metal around the piston bore.
