1. In automotive superchargers, this is analogous to the operation of a bypass valve . 2. It uses a fully catalysed stainless steel exhaust system with active bypass valves . 3. The TD04 compressor has a compressor bypass valve built right into the compressor housing. 4. Reactor pressure in a BWR is controlled by the main turbine or main steam bypass valves . 5. It boasted a supercharging system from Formula 1 in miniature with intercooler, bypass valve , and thermostatic valve. 6. The second method is to use a bypass valve which feeds charge air directly to the exhaust manifold. 7. To maintain the correct operating temperature of 62 degrees C, a bypass valve was incorporated in the cooling circuit. 8. The steam bypass valves that lead to the main condenser were opened and Limerick went through a normal hot shutdown process. 9. The amount of bleed air cooling at the heat exchanger can be controlled by the hot air bypass valve ( H-valve ). 10. When the ignition is switched off, the ECU winds the bypass valve fully open to provide enough air the next time the engine is started.
