  • Patent number: 10767813
    Abstract: A lubricant injector includes a body having an inlet fluidly coupleable to a lubricant source, an outlet, and an elongated bore extending along an axis and having an outer end proximal to the body second end, a closed inner end spaced axially from the body first end, a first port, and a second port disposed generally between the bore closed end and the first port. A delivery chamber separate from the bore has an inlet port and an outlet port fluidly coupled with the body outlet. A piston disposed within the bore divides the bore into an operating chamber coupled with the first port and a measuring chamber coupled with the second port. The operating chamber is fluidly coupled with the inlet and the measuring chamber is located between the bore closed end and the operating chamber and is fluidly coupleable with the inlet and alternatively with the delivery chamber.

  • Patent number: 10351414
    Abstract: A liquid dispenser includes a container and a lid. When the lid is mounted on the container, the container supports passaging including a gas supply inlet and a venturi. A control valve in fluid communication with the passaging is adjustable to a dispensing configuration and an evacuation configuration and a separate mode selector valve is adjustable to a dispensing configuration and an evacuation configuration. The dispenser dispenses liquid when both valves are in the dispensing configuration and evacuates liquid when both valves are in the evacuation configuration. The mode selector valve can block flow through a pressurization passage of the passaging in the evacuation configuration and through the venturi or other evacuation passage in the dispensing configuration.

  • Patent number: 10351413
    Abstract: A pneumatic liquid dispenser includes a container and a lid. When the lid is mounted on the container, the container supports passaging defining a gas supply inlet for receiving pressurized gas, a gas outlet for delivering pressurized gas to the container, and a gas flow path between the inlet and the outlet. A pressure valve is located between the gas supply inlet and the gas outlet. The pressure valve is configured to automatically permit gas flow along the gas flow path when pressure in the interior of the container is less than a threshold pressure and to automatically block gas flow along the gas flow path when pressure in the interior of the container is greater than the threshold pressure. When gas flows freely through the gas flow path, the gas pressurizes the container to dispense liquid in the container through a liquid passage.

  • Patent number: 10353404
    Abstract: A liquid flow device includes a container and a lid. When the lid is mounted on the container, the container supports a gas supply passage, a pressurization passage, an evacuation passage, and a liquid passage. A control valve is located between the gas supply passage and both the pressurization passage and the evacuation passage. In one configuration, the control valve provides communication between the gas supply passage and pressurization passage to pressurize the container and dispense liquid from the container through the liquid passage. In another configuration, the control valve provides communication between the gas supply passage and evacuation passage to create a vacuum pressure inside the container for evacuating liquid into the container through the liquid passage.

A shaft is disposed within the housing and is rotatable about a central axis. A flow detector is mounted on the shaft and disposed at least partially within the passage. The flow detector includes a rotatable, generally cylindrical body that rotates about a central axis as the fluid flows. A magnet is disposed within the housing such that the central axis extends through it, and is configured to rotate simultaneously with the body about the central axis. A magnetic encoder is disposed within the housing and configured to sense rotation of the magnet as the flow detector angularly displaces about the central axis so as to detect angular displacement of the flow detector.

  • Patent number: 9841141
    Abstract: A method includes providing a bearing housing configured to house a bearing, the bearing housing enclosing a free volume for receiving a lubricant and including a shaft in a shaft opening, filling the free volume with the lubricant, providing an exclusion seal between the shaft opening and the shaft, the exclusion seal being repeatably and non-destructively shiftable from a sealing state and a release state, the exclusion seal being shiftable from the sealing state to the release state by increasing a pressure in the bearing housing to above a first level and being shiftable from the release state to the sealing state by decreasing the pressure to below the first level; and continuously maintaining a film of the lubricant between the exclusion seal and the shaft by repeatedly causing the pressure of the lubricant in the free volume to rise above and fall below the first level.

  • Patent number: 9683697
    Abstract: Methods and systems for determining lubrication flow dispensed to lubrication points. Lubricant delivery is determined based upon the difference between volume measurements detected as the lubricant is delivered to the lubrication points, and volume measurements detected as the lubricant is vented after delivery. A flow sensor in the lubricant supply line measures lubricant delivered and lubricant vented and a controller determines the amount dispensed based upon the difference between the delivered and vented measurements.

  • Patent number: 9512963
    Abstract: A lubrication system vent valve includes a valve body having a flow passage with an inlet fluidly coupled with a supply and an outlet fluidly coupled with a dispenser, and a vent passage with an inlet port fluidly coupled with the flow passage and an outlet port. A closure element disposed within the vent passage has a threaded portion and is linearly displaceable between an open position where the vent ports are fluidly coupled to permit lubricant flow from the primary passage and out of the body through the vent outlet port, and a closed position at which fluid flow between the vent ports is substantially prevented. A motor has a shaft with a threaded portion engaged with the closure element such that shaft rotation in one direction displaces the closure element toward the closed position and shaft rotation in an opposing direction displaces the element toward the open position.
