Turbocharged internal combustion engine with a system for regulating the supercharged air pressure

摘要

This device comprises a pressure controller connected to the fluid source through a first calibrated aperture. This pressure controller controls a valve located on a by-pass circuit connected in parallel with the utilization circuit, and is provided with a second calibrated aperture for fluid discharge and with means for closing said second aperture when the pressure in the controller reaches a set value lower than the pressure required for actuating the by-pass valve. The use of this device is particularly suitable in supercharged engines.
