Beschreibung
Zusammenfassung:	An assembly for a fluid circuit of a turbine engineincludes a main branch, a fluid control valve, and a bypass branch which is arranged in parallel to the main branch. The fluid control valve includes a main outlet which is fluidly connected to the main branch and a bypass outlet which is fluidly connected to the bypass branch. The fluid control valve including a shutter, a spring for biasing the shutter, and control members for electrically controlling the shutter to a main open position or a bypass position. The spring for biasing the shutter is configured to bias the displacement of the shutter to the bypass position when a fluid pressure value is lower than a first threshold value.
