Patent number: 6952932Abstract: Method and apparatus for heating gases cooled by an aftercooler that receives hot gases from a compressor. The method includes the steps of directing at least a portion of said hot gases to means for bypassing the aftercooler, and using the bypass means to direct hot gases to a location that receives cooled gases from the aftercooler. The hot gases are used at the location to heat the cooled gases when ambient temperature is at or below freezing, and are used downstream from the aftercooler when moisture freezes in the aftercooler.Type: GrantFiled: September 12, 2003Date of Patent: October 11, 2005Assignee: Westinghouse Air Brake Co.Inventors: Walter E.

Publication number: 20010003301Abstract: An air compressor and aftercooler combination in which the aftercooler is located in front of the air compressor. The aftercooler is connected to the air compressor for receiving hot, high pressure air and for effectively cooling the same such that the temperature of the high pressure air delivered by the aftercooler approaches that of atmospheric ambient. A fan is located to draw and direct atmospheric ambient air to the compressor and to and through aftercooler for effective cooling of the high pressure air in the aftercooler, as received from the compressor.Type: ApplicationFiled: July 14, 1999Publication date: June 14, 2001Inventors: WALTER E.

Patent number: 6203285Abstract: Apparatus for rapidly unloading air pressure in an intercooler to atmosphere when a compressor pneumatically connected to the intercooler is unloaded. The apparatus includes a governor pneumatically connected to a reservoir, that, in turn, is connected to receive pressurized air from the air compressor. The governor has a pressure sensing device operable to order unloading of the compressor when air pressure level in the reservoir tank reaches a preset level. An electrically operated valve is pneumatically connected to the intercooler and connected electrically to the pressure sensing device of the governor, with the electrically operated valve being effective to exhaust air pressure in the intercooler when the valve receives an unload signal from the pressure sensing device. The compressor is driven, by an electrical motor having one or more speed configurations, with transition occurring between one configuration and another when the compressor is unloaded.Type: GrantFiled: May 18, 1998Date of Patent: March 20, 2001Assignee: Westinghouse Air Brake CompanyInventors: Daniel G.
