Abstract: The invention relates to an assembly (30) for an electrically operated valve in the automotive field aimed to increase the injection pressure of a fuel within a combustion chamber, said assembly comprising both a coil unit (32) wherein a solenoid can control the movements of the electrically operated valve along a given axis (35) and an hydraulic unit (31) to provide fuel at the injection pressure, an elastic ring (34) being axially compressed between said coil unit (32) and said hydraulic unit (31).
A part (36) of the coil unit (32) and a part (37) of the hydraulic unit (31) are locked under a mechanical pressure due to an elastic deformation of said coil unit part (36) and/or said hydraulic unit part (37) while the elastic ring (34) maintains an axial load keeping said coil unit part (36) and/or said hydraulic unit part (37) under tension.
