  • Patent number: 8157243
    Abstract: An evacuation valve for a metering device for a liquid medium is disclosed. The valve includes a seal holder having a chamber formed therein and a seal. An elastomeric material fills the chamber to form the seal. The seal includes a smooth, flat sealing surface located above the seal holder. The inclusion of a lip in the chamber retains the seal; a non-circular lip prevents rotation of the seal.

  • Patent number: 7975805
    Abstract: A system for lubricating a lubrication target located within a refrigerated atmosphere. The system includes a lubricant source, a pressurized air source, and at least one pneumatically-activated pump in connection with the lubricant and air sources. The pump output is connected to a conduit that terminates at a spray nozzle for delivering the lubricant to the target in a controlled fashion. Pressurized air may be used to better control the lubricant delivery. The temperature of the lubricant and air flowing through the conduits is regulated so that the fluids will flow predictably at very cold temperatures.

  • Patent number: 7600984
    Abstract: The metering device for a liquid medium comprises a cylinder and a piston operatively disposed therein to define a metering chamber ahead of the piston. The outlet end of the cylinder is open and closed by an evacuation valve. The piston is driven forwardly through a working stroke to force the liquid medium in the metering chamber out of the chamber and past the evacuation valve. A check valve located in the metering chamber moves from a closed to an open position on each working stroke to preclude entrapment of air in the metering chamber and thus provide for more accurate metering. The metering device may include means to regulate the length of the working stroke.

  • Patent number: 6478115
    Abstract: A lubrication apparatus lubricates the chain and trolley components of an overhead conveyor supported by a rail. Immediate lubrication is provided to such components without the need of a timer, thereby preventing any lubricant from being applied to non-target surfaces. The apparatus is mounted to the rail using hooks so that the integrity of the rail is preserved and relocation is simple. The apparatus can withstand an impact from a passing mis-aligned trolley. The apparatus can be adapted to lubricate chain and trolley components on different rail profiles, including an I-beam.
