Patent number: 9512752Abstract: In accordance with certain embodiments, the present invention provides a modular approach to a lubrication package. Certain components such as the filter and cooler are directly connected to a block that has connections to accept them and internal porting to establish the proper flow paths for circulation, cooling and filtration of the circulating lubricant. The block can accept one or more coolers and one or more filters. The isolation valving for redundant equipment can also be integrated into the block. Many connections that had been used in past designs for the piping network are integrated into the block. The block can also be close mounted to the reservoir while a submersible pump further saves space and piping connections. Indeed, having the ability to maintain mechanical equipment (e.g.Type: GrantFiled: July 26, 2013Date of Patent: December 6, 2016Assignee: Ingersoll-Rand CompanyInventors: Edward S.

Patent number: 9372022Abstract: Provided in some embodiments is a system that includes a gas compressor including an engine, a compressor driven by the engine, and a vapor absorption cycle (VAC) system driven by waste heat from the compressor, wherein the VAC system is configured to cool at least one medium. In other embodiments is provided a method that includes generating waste heat while compressing a gas, driving a vapor absorption cycle (VAC) system with the waste heat, and cooling at least one medium via the VAC system.Type: GrantFiled: January 12, 2015Date of Patent: June 21, 2016Assignee: Ingersoll-Rand CompanyInventor: Edward S. Czechowski

Patent number: 9371838Abstract: The volute is cast integrally with the gearbox base to allow closer radial tolerances to be used to improve efficiency. In the preferred embodiment, compressors for multi-stage compression are assembled with intercoolers and the integral volute is cast together with the impeller housing and the lower gearbox housing and the associated intercooler. Efficiency increases of 2% or more are achievable. In multistage applications, efficiency gains in the early stages are compounded in each subsequent stage. Speed changes that change center distance between bull gear and pinion are accommodated by an offset opening in the inlet and diffuser that can line up with the impeller shaft as well as an offset opening in the fluid seal despite a pinion gear change, by reorientation and remounting of those parts.Type: GrantFiled: March 8, 2013Date of Patent: June 21, 2016Assignee: Ingersoll-Rand CompanyInventors: Robert Small, Robert M. Kolodziej, Edward S. Czechowski

Patent number: 9243640Abstract: A system in some embodiments includes a machine block comprising features configured to support moving machine components within a lubricating fluid, wherein the machine block includes an integral valve block configured to route the lubricating fluid through a first filter without a second filter and configured to route the lubricating fluid through the second filter without the first filter. Further embodiments include a method that includes switching circulation of a lubricant between a first filter and a second filter in response to an angular position of a valve disposed in a valve block integral to a machine block having moving components lubricated by the lubricant.Type: GrantFiled: July 27, 2013Date of Patent: January 26, 2016Assignee: Ingersoll-Rand CompanyInventors: Jeffrey M.

Publication number: 20150240830Abstract: An integrally-geared centrifugal compressor has a drive mechanism and a gear box operatively engaged with the drive mechanism. The gear box includes a main input gear driven by the drive mechanism and a pinion shaft driven by the main input gear. The pinion shaft is driven at a higher rotational speed (generally above the first critical speed) compared to the main input gear. The compressor further includes at least one process stage for compressing a fluid medium. The at least one process stage has at least one centrifugal compressor with at least one impeller operatively engaged with the pinion shaft. At least one thrust bearing having a bearing surface is provided in operative engagement with the pinion shaft. The bearing surface is made from a non-metallic material, such as a poly-ether-ether-ketone (PEEK) or equivalent material.Type: ApplicationFiled: February 26, 2014Publication date: August 27, 2015Inventors: Edward S. Czechowski, Michael G. Evan, John R. Badini, Matthew S. Zowacki, Cheng Jin, Shane P. Lynch

Patent number: 9033651Abstract: A system, in certain embodiments, includes a seal assembly having a seal body. The seal body includes an inlet buffer port and an outlet eduction port. The inlet buffer port is configured to receive a compressed buffer gas, such as shop air, which is injected into the inlet buffer port. The compressed buffer gas blocks the flow of a compressed process gas, such as land fill gas, by opposing the flow of the compressed process gas through the seal assembly. Both the compressed buffer gas and the compressed process gas may be expelled through the outlet eduction port.Type: GrantFiled: April 22, 2010Date of Patent: May 19, 2015Assignee: Ingersoll-Rand CompanyInventors: Edward S. Czechowski, Michael A. Nuchereno, Paul A. Leising, Nathan P. Vetter

Patent number: 8979506Abstract: Apparatus and methods to prevent the rotation of a shaft in one direction using a device comprising a collar disposed around the shaft, a locking arm with an unlocked position and a locked position, and an actuator capable of moving the locking-arm between the unlocked and locked position. When the locking arm is in the unlocked position, the collar and shaft are allowed to rotate in a first direction. However, when the locking arm is in the locked position, the collar and shaft are prevented from rotating in a second direction. This device can also be used to prevent the reverse rotation of a rotating compressor.Type: GrantFiled: January 17, 2006Date of Patent: March 17, 2015Assignee: Ingersoll-Rand CompanyInventors: Omar M. Kabir, Edward S. Czechowski
