Temperature Management System For A 2Cd Type Air Compressor
US Patent:
2010012, May 20, 2010
Filed:
Nov 19, 2008
Appl. No.:
12/273664
Inventors:
Jeffrey J. Hritz - Baldwin PA, US
Assignee:
WABTEC HOLDING CORP. - Wilmerding PA
International Classification:
G05D 23/00, F28F 13/12, G05B 15/00, B23P 19/04
US Classification:
165287, 165121, 700275, 29700
Abstract:
A temperature management system for an air compressor includes a plurality of cooling fans coupled to an intercooler of the air compressor; an electrical relay comprising a coil and contacts operated by the coil; and a temperature switch coupled to the coil of the electrical relay. The contacts are located between the cooling fans and an electrical power supply. The temperature switch opens at a temperature above a predetermined temperature at a high pressure inlet of a high pressure stage of the air compressor, thereby closing the contacts of the electrical relay which applies power to the cooling fans.
Air Compressor Pre-Lubrication System
US Patent:
2010019, Aug 5, 2010
Filed:
Feb 5, 2009
Appl. No.:
12/366176
Inventors:
Jeffrey Hritz - Pittsburgh PA, US
Assignee:
WABTEC HOLDING CORP. - Wilmerding PA
International Classification:
F01M 5/00
US Classification:
184 63
Abstract:
The air compressor pre-lubrication system includes an oil pump, a priming tank, and a control valve. The oil pump is connected to an oil sump and includes a discharge line connected to an air compressor. The priming tank is connected to the oil pump to receive pressurized oil. The control valve is provided in an outline line connected to the priming tank and is further connected to the oil pump discharge line. The priming tank is configured to maintain a charge of oil from the oil pump and selectively release the charge of oil through actuation of the control valve. An auxiliary pre-lubrication oil pump may replace the priming tank. The pre-lubrication oil pump is connected to the oil sump and is fluidly coupled to the discharge line leading to the air compressor.
Air Compressor With Oil Pump Inlet Strainer And Bypass Valve
US Patent:
2012023, Sep 20, 2012
Filed:
Mar 14, 2011
Appl. No.:
13/047034
Inventors:
Jeffrey Hritz - Pittsburgh PA, US
Assignee:
WABTEC HOLDING CORP. - Wilmerding PA
International Classification:
B01D 35/14, F01M 11/03
US Classification:
210130, 21016702
Abstract:
An air compressor with oil pump inlet strainer bypass features includes a bypass valve assembly in fluid communication with the air compressor crankcase to provide lubricating oil to the dynamic compressor components, or simply to the air compressor. The bypass valve assembly includes a valve housing defining an interior chamber and an oil strainer screen engaged with the valve housing to filter the lubricating oil entering the interior chamber. A bypass valve is in fluid communication with the interior chamber and includes a valve body having a bypass port and an indicator port. An optional suction tube is connected to the bypass port on the valve body. An indicator assembly is connected to the indicator port on the valve body.
