<p>This device comprises a manometric gauge connected to a fluid source through a first calibrated aperture. The manometric gauge controls a valve located in a by-pass circuit connected in parallel with a 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 gauge reaches a set value lower than the pressure required for actuating the by-pass valve. The use of this device is particularly adapted for use in supercharged engines.</p> |
