Abstract: A coil of a stator for an electric motor is disclosed. The coil includes a reel forming a tooth of the stator. The reel includes a tubular central shaft including multiple grooves formed on its periphery between a first end of the central shaft configured to be oriented towards the center of the stator and a second end of the central shaft configured to be oriented towards the outside of the stator. The grooves are configured to receive a turn of a winding wire wound around the reel. The reel also includes a first retaining collar located at the first end of the central shaft, a second retaining collar located on the second end of the central shaft, and a winding formed by the winding wire configured to be wound around the reel between the first retaining collar the second retaining collar.

Abstract: A coil of a stator for an electric motor is disclosed. The coil includes a bobbin which forms a tooth of the stator. The bobbin includes a tubular central shaft with a plurality of channels formed along its perimeter between a first end of the bobbin that is configured to face towards the middle of the stator. The bobbin also includes a first retaining flange situated on the first end of the central shaft, a second retaining flange situated on the second end of the central shaft, and a winding wire configured to be wound in the form of turns around the bobbin. The ends of the winding wire are positioned at the first end of the bobbin so as to enable electrical connections toward the center of the stator. The bobbin includes a material cutout extending between the first and second ends of the bobbin.

Abstract: A solenoid valve closure part comprising a seat and a solenoid coil, the valve closure part including the free end of a movable core within the hub of the coil, and further including an intermediate component capable of bearing against the seat and itself comprising a second seat, facing the first seat and of a lesser cross section than that of the first seat, the free end of the movable core being capable of bearing against the second seat and an elastic element being provided to press the intermediate component away from the first seat.
