Publication number: 20080245987Abstract: The present invention provides a two-stage turbocharger unit having a valve that will help to create a smooth transition of exhaust gas energy from the high-pressure turbine (HP) turbine to the low-pressure (LP) turbine. The LP and HP turbines are positioned such that the valve can be in one position to force all of the exhaust gas to flow through the HP turbine and when in another position to force all of the exhaust gas through the LP turbine. When the valve is placed in an intermediary position, the exhaust gas can be variably directed to flow through both turbines, with the percentage of exhaust gas flowing through each turbine being dependent on the position of the valve.Type: ApplicationFiled: October 2, 2007Publication date: October 9, 2008Applicant: BorgWarner Inc.Inventors: Thomas A.

Publication number: 20080245988Abstract: A valve design that enables a positive shaft seal to be obtained in an inexpensive manner by reducing the need for close tolerances heretofore required in prior art designs. This unique valve design employs a shaft seal that is adapted for transverse and/or angular movement during assembly of the valve for aligning to the shaft at an alignment position in which it is held after assembly of the valve by a holding device such as a seal nut or spring.Type: ApplicationFiled: April 2, 2008Publication date: October 9, 2008Inventors: Anton Maes, Brian M.

Publication number: 20080245992Abstract: The invention relates to the mixture of natural gases based on hydrocarbons (HC) which do not damage the ozone layer and which have an insignificant greenhouse effect, said gases being substitutes for CFC gases R-12 and R-22, whereby the R-12 substitute is known as HC-12 and the R-22 substitute is known as HC-22. The aforementioned mixtures, which generate a specific pressure/temperature curve, improve the efficiency of air conditioning and refrigeration compression systems. Specifically, since condensation pressures are lower, less pressure and, consequently, less work is required from the compressor, and hence power consumption is reduced. In addition, the refrigerant gases, based on HC mixtures, replace CFCs and HCFCs and are compatible with materials and elements used in commercial refrigeration and air conditioning systems. The resulting mixture generates a specific pressure/temperature curve with a range of plus or minus 5%.Type: ApplicationFiled: May 4, 2005Publication date: October 9, 2008Inventor: Ruben Dario Ochoa Vivanco
