Abstract

1532516 Controlling turbochargers GARRETT CORP 25 March 1976 [31 March 1975(2)] 12118/76 Heading F1B To prevent over pressurization by a turbocharger 28, 26 Fig. 2 at part throttle the by-pass valve 46 is controlled via a servo linkage in response to throttle valve 20 position, acting to adjust the relief valve 82 to control the pressure in chamber 64, turbine inlet pressure acting on valve 46, compressor outlet pressure acting in chamber 60 and compressor inlet pressure acting in chamber 62. A cam 86 adjusts the relief valve 82 in a fluidpressure circuit supplied from the engine oil pump. As shown, the valve tends to be opened by the pressure in duct 30 and chamber 60 and closed by the hydraulic pressure in chamber 64. The difference in cross-sectional areas of flexible walls 56, 58 causes the valve to tend to open by an amount related to the difference in the pressure between the compressor inlet and outlet. Fig. 3 shows an alternative arrangement wherein a control unit housed in case 148 form an 'OR' mechanism. turbine flow being reduced if the force due to compressor delivery pressure exceeds the bias force produced by spring 160 or the turbine inlet pressure exceeds that due to the hydraulic force controlled in response to the throttle valve position. The hydraulic chamber 164 is defined by an intermediate element 152 which is slidingly supported on member 162. Figs. 4 and 5 (not illustrated) show arrangements operating similarly to Fig. 3 but wherein the force opposing that due to the turbine inlet pressure is produced by a mechanical linkage acting via a cam on the end of the valve stem, the linkage being supported on the intermediate element for movement therewith.
