ABSTRACT:
A mechanical supercharger has a by-pass structure in the form of a valve body unitarily fixed to the supercharger housing at an end thereof opposite the drive gears for synchronously rotating the rotor shafts. The valve body contains a by-pass passage which is normally closed by a valve and which fluidically connects the outlet and the inlet of the compressor for permitting compressed gas to return to the inlet. The valve is slidably mounted on a shaft and is normally biased into the closed position by a spring, so that the valve will open the by-pass when the compressed gas pressure exceeds the spring force. The shaft itself is mounted to a diaphragm mechanism which can retract the shaft and open the valve in response to a pressure signal to the valve when supercharging is not necessary. Engine wear and fuel consumption are thus improved.
