  • Patent number: 10883658
    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.

  • Patent number: 10801633
    Abstract: A valve body has an outside surface and a cylinder. The cylinder has an inlet chamber and an outlet chamber. A piston has a head at one end and a foot at the end opposite the head and a piston body between the head and the foot. A cross channel extends from a first side of the piston body. A longitudinal channel is in fluid communication with the cross channel and extends to the outlet chamber. The piston is positioned in the cylinder so that it can be moved to an open position in which the cross channel is in fluid communication with the inlet chamber and a closed position in which the cross channel is not in fluid communication with the inlet chamber.
