Solenoid valve for controlling the flow of a fluid in a hydraulic circuit, comprising a valve body having at least one fluid duct, a stopper for allowing or preventing the flow of fluid in the fluid duct, a mechanical connection to actuate the stopper, an electromagnetic actuator arranged to actuate the mechanical connection, and a coupling between the electromagnetic actuator and the valve body via a jacket surrounding the electromagnetic actuator and engaged on a shoulder of the valve body. The jacket holds the electromagnetic actuator in axial engagement against the valve body in a direction of engagement. The shoulder comprises two matching half-washers engaged radially in a peripheral groove of the valve body.

What is claimed: 1. A solenoid valve for controlling the flow of a fluid in a hydraulic circuit, comprising: a metallic valve body defining a valve portion having at least one fluid duct, at least one peripheral groove, a stopper for allowing or preventing the flow of fluid in the fluid duct and a mechanical connection to actuate the stopper, an electromagnetic actuator arranged to actuate the mechanical connection, a coupling between the electromagnetic actuator and the valve body, via a jacket surrounding the electromagnetic actuator and engaged with a shoulder fitted to the valve body, that holds the electromagnetic actuator in axial engagement against the valve body in a direction of engagement, wherein the valve body has a first end that is coupled to the electromagnetic actuator and a second end, the second end an axi-symmetric outer cylindrical shape inside which the entire valve portion is contained, and wherein the shoulder comprises an assembly of two matching half-washers, engaged radially in the peripheral groove and held radially in the peripheral groove by the jacket. 2. The solenoid valve according to claim 1, wherein the external diameter of the electromagnetic actuator is markedly greater than the external diameter of the valve body around the direction of engagement. 3. The solenoid valve according to claim 1, wherein the electromagnetic actuator comprises a generally cylinder-shaped winding defining at its center a cylindrical housing between a first end and a second end along the direction of engagement, a casing, placed around the winding, closing off the cylindrical housing of the winding on the first end and holding a ferromagnetic washer against the first end to form a first pole of the magnetic circuit, a magnetic core that can be moved in longitudinal translation in the cylindrical housing of the winding. 4. The solenoid valve according to claim 3, wherein the mechanical connection comprises a rod, sliding in an axial cylindrical bore of the valve body to actuate the stopper during the movements of the movable magnetic core. 5. The solenoid valve according to claim 3 wherein the valve body comprises an axial nose partially engaged in the cylindrical housing of the winding and forming a second pole of the magnetic circuit. 6. The solenoid valve according to claim 5, wherein the axial nose is a fixed ferromagnetic core fitted at the end of the valve body. 7. The solenoid valve according to claim 6, wherein the fixed core is held on the electromagnetic actuator by at least one core retaining piece, fitted and attached on the periphery of the fixed core and held by the jacket. 8. The solenoid valve according to claim 7, wherein the said at least one core retaining piece is made of ferromagnetic material and magnetically connects the fixed core to the jacket, the valve body being made of nonmagnetic material. 9. The solenoid valve according to claim 3, wherein the valve body is made of ferromagnetic material, and at least one of the matching half-washers is made of ferromagnetic material and magnetically connects the valve body to the jacket. 10. The solenoid valve according to claim 1, wherein in at least one of the said matching half-washers is extended radially to form an attachment lug of the solenoid valve. 11. A solenoid valve for controlling the flow of a fluid in a hydraulic circuit, comprising: a metallic valve body having at least one fluid duct, at least one peripheral groove, a stopper for allowing or preventing the flow of fluid in the fluid duct and a mechanical connection to actuate the stopper, an electromagnetic actuator arranged to actuate the mechanical connection, a coupling between the electromagnetic actuator and the valve body, via a jacket surrounding the electromagnetic actuator and engaged with a shoulder fitted to the valve body, that holds the electromagnetic actuator in axial engagement against the valve body in a direction of engagement, wherein the valve body has an axi-symmetric outer cylindrical shape that defines a largest outside diameter, the largest outside diameter is of one diameter over an entire length of the valve body, other than for the at least one fluid duct or at least one peripheral groove. 12. The solenoid valve according to claim 1, wherein the shoulder comprises an assembly of two matching half-washers, engaged radially in the peripheral groove and held radially in the peripheral groove by the jacket.
