The invention concerns a solenoid valve assembly intended to be fixed to an assembly comprising a motor (1), the solenoid valve assembly comprising: a pneumatic solenoid valve (24) comprising a body (38), an inlet (30) intended to be connected to a supply pressure, an outlet (26) intended to supply a control pressure and an actuator allowing control of the control pressure, first vibration damping means (39, 39') produced by the motor during its operation, arranged externally to the body (38) of the solenoid valve (24), the first damping means (39, 39') being intended to connect the body (38) of the solenoid valve (24) to the motor (1), characterized in that the solenoid valve (24) comprises second damping means (41, 37) arranged internally to the body (38) of the solenoid valve (24), the first and second damping means (39, 39') being designed so that they form a device for dual decoupling of vibrations between the motor (1) and the actuator.
