Patent number: 8157243Abstract: 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.Type: GrantFiled: September 15, 2008Date of Patent: April 17, 2012Assignee: Oil-Rite CorporationInventor: Michael J.

Patent number: 7975805Abstract: 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.Type: GrantFiled: April 1, 2005Date of Patent: July 12, 2011Assignee: Oil-Rite CorporationInventor: Michael J. Wech

Patent number: 7600984Abstract: 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.Type: GrantFiled: August 15, 2006Date of Patent: October 13, 2009Assignee: Oil-Rite CorporationInventors: Donald G. Gruett, Michael J. Wech

Patent number: 7550689Abstract: A reservoir assembly is disclosed including a one-piece integrally formed fluid level switch housing and outlet wherein the switch housing can be rotated 360 degrees about its longitudinal axis to locate the outlet at any desired position. A conventional fitting may be integrally formed at the outlet. The orientation of the outlet may be changed at any time after the manufacturing process.Type: GrantFiled: April 24, 2007Date of Patent: June 23, 2009Assignee: Oil-Rite CorporationInventors: Michael J.

Patent number: 6478115Abstract: 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.Type: GrantFiled: May 26, 2000Date of Patent: November 12, 2002Assignee: Oil-Rite CorporationInventors: Michael J.
