A system for cooling internal combustion engine pistons comprising an oil pump driven by the engine, jets projecting oil on the pistons, and a control device (2) interposed between the oil pump and the jets, where the control device comprises a valve (14) positioned between an oil inlet pipe (8) connected to the pressurised oil pump and a jet supply pipe (10), where said valve allows the oil to flow out from the pump to the jets when the oil pressure is at least equal to a threshold pressure, and where the device also comprises a solenoid valve (22) capable of causing the valve (14) to close by permitting the pressurised oil to be brought into contact with the closure member (16), in a direction of closure of the valve (14).

1. A device for controlling the supply of a system from a fluid under pressure source comprising: a valve configured to be positioned between a fluid under pressure inlet pipe and a supply pipe of said system, said valve allowing the fluid under pressure to flow out from the source to the system when the pressure of the fluid is at least equal to a threshold pressure, the valve having a closure member and a return spring supported on a second face of the closure member, a first face of the closure member opposite the second face being configured—to receive an effort from the fluid under pressure to cause the opening of the valve;a control pipe connecting the fluid under pressure inlet pipe and the second face of the closure member, said control pipe being configured to convey the fluid under pressure to the second face of the closure member; anda solenoid valve configured to be installed in the control pipe, said solenoid valve being configured to control contact of the second face of the closure member with the fluid under pressure, and the solenoid valve being closed if there is no electrical power. 2. A control device according to claim 1, in which the valve comprises a sleeve for guiding the return spring, said sleeve being immobile, also forming a stop for the closure member in its maximum opening position, and the sleeve comprising a recess receiving one end of the return spring. 3. A control device according to claim 1, in which the closure member is a piston, comprising a recess in its second face receiving another end of the return spring. 4. A control device according to claim 2, in which the fluid under pressure arrives at the second face of the closure member through the sleeve. 5. A control device according to claim 1, in which the solenoid valve is a proportional or “on-off” solenoid valve. 6. A control device according to claim 1, in which the valve comprises at least one spur leading to a chamber formed by the second face of the closure member to allow the outflow of the fluid trapped in this chamber when the valve is opened, said spur being configured to be connected to a low-pressure tank, and dimensions of said spur being such that they allow pressure to be established in said chamber when the solenoid valve is opened. 7. A control device according to claim 1, in which the solenoid valve comprises: a mobile core in a coil;a magnetic circuit guiding a magnetic field able to be generated by the coil;a spring interposed between a magnetic stop and the core pushing the core to the outside of the coil; anda closure member pressed against a seat by the spring through the core, in which the core is attracted inside the coil when the magnetic field is generated by the coil, allowing the closure member to become separated from the seat. 8. A control device according to the claim 7, in which the spring of the solenoid valve is supported between the magnetic stop and a shoulder of the core, a part of the core being surrounded by the spring such that, when the core abuts against the magnetic stop the spring is not completely compressed. 9. A control device according to the claim 1, comprising a casing in which are installed the valve and the solenoid valve so as to form a secure assembly configured to be installed in a housing comprising the inlet, supply and control pipes. 10. A system for cooling at least one internal combustion engine piston comprising: an oil pump driven by the engine;at least one jet projecting oil on the piston, said jet being supplied by the oil pump;a device for controlling the supply of a system from a fluid under pressure source interposed between the oil pump and the at least one jet, said device comprising a valve configured to be positioned between a fluid under pressure inlet pipe and a supply pipe of said system, said valve allowing the fluid under pressure to flow out from the source to the system when the pressure of the fluid is at least equal to a threshold pressure, the valve having a closure member and a return spring supported on a second face of the closure member, a first face of the closure member opposite the second face being configured to receive an effort from the fluid under pressure to cause the opening of the valve, a control pipe connecting the fluid under pressure inlet pipe and the second face of the closure member, said control pipe being configured to convey the fluid under pressure to the second face of the closure member, and a solenoid valve configured to be installed in the control pipe, said solenoid valve being configured to control contact of the second face of the closure member with the fluid under pressure, and the solenoid valve being closed if there is no electrical power,wherein the control device is installed on an engine block in which are installed the pressurized oil inlet pipe connected to the oil pump, the supply pipe connected to the jet, and the control pipe connected to the pressurized oil inlet pipe.
