Abstract
The invention is directed to a divider block assembly made from one piece of material. Traditional divider blocks require modular sections so that piston alignment can be calibrated precisely. The current invention uses replaceable pistons and sleeves that are suitable for use at high fluid pressures. The use of these pistons also allows for a single, bodied, one-piece, metal divider body, rather than the conventional multiple block divider blocks, which allows for a more efficient manufacturing method and stronger, more reliable, and more efficient lubricant dispensing system. The use of any of these aspects separately can improve performance, and not all are required in every embodiment.
Claims7
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:
- one divider block made from a single integral and gaplessly continuous piece of material having;
- a single inlet, at least three outlets, at least three piston bores, each piston bore sized to receive a replaceable sleeve, for each piston bore, a replaceable sleeve with an outlet passage for lubricant, a single piston in each of the replaceable sleeves, the single piston dispensing lubricant by the pressure of the incoming lubricant, multiple seals between each of the replaceable sleeves and the corresponding piston bore, the multiple seals separating hydraulic circuits within the diver block assembly, the piston sequentially opening and closing hydraulic circuits as the pistons move in the corresponding replaceable sleeve, such that lubrication is dispensed sequentially from each of the three outlet passages without check valves in the divider block;
- and
- at least one end plug that is aligned with the replaceable sleeve.
