A cooling circuit comprises a cylinder block and a cylinder head block, these blocks each including cooling elements the form of integrated portions of circuit. The cooling circuit also includes at least a first, a second and a third separate external loops for external recirculation or reinjection mounted in parallel and looped on the integrated cooling elements. A circulating pump is connected fluidically to the integrated cooling element and to the three recirculation loops causing the fluid to circulate in the integrated cooling element and in the three recirculation loops. The at least three recirculation loops offer at least one common fluid node and are at least partially overlapping. A single actuator controls the flow of liquid circulating in the at least three recirculation loops.

An assembly forming part of a circuit for circulating a liquid fluid and comprising a pump and at least one valve unit with proportional control, in which the valve is mounted in series with said pump in that part of the circuit, characterised in that the valve unit (2) comprises, apart from the valve (3) itself, firstly an electrical actuator (4) and a position sensor (5) which are fixed to the movable member (3′) sealing the valve (3) for displacement therewith, and secondly a control means (6) controlling the actuator (4) according to the position of the movable member (3′) indicated by the sensor (5) and a reference signal, said valve unit (2) being subjected to a procedure indexing the position of the movable member (3′) and setting parameters for the control means (6) at the beginning of each new operating cycle of the assembly, and that the pump (1) is rotated at a constant speed, if appropriate selected from a limited number of predetermined speeds, at least during part of each operating cycle of the pump (1).
摘要:
A slide-valve device sliding in a predetermined axial direction, includes a valve body having two chambers, the first chamber including a lateral fluid-intake opening and a fluid-outlet opening provided with a normally closed, conditionally opening plug device, the second chamber including first and second lateral fluid-outlet openings, mutually offset in the axial direction. Two inner regions of the second chamber are arranged contiguously in the axial direction and communicate with one another via an opening or an internal passage, and in that the sliding drawer includes a first plug member suitable for selectively plugging the communication opening or the internal communication passage or opening between the two regions and a second plugging member suitable for preventing fluid communication between the second lateral fluid-outlet opening of the second chamber and a first region of the second chamber, within a predetermined range of translation of the sliding drawer.

A pump/valve assembly forming part of a circuit for circulating a liquid fluid has a pump and a proportional-control valve unit (2) in series with the pump. The valve unit (2) has a valve (3), an electrical actuator (4) and a position sensor (5) which are fixed to a movable member (3′) sealing the valve (3) for displacement therewith, and control means (6) controlling the actuator (4) according to the position of the movable member (3′) indicated by the sensor (5) and a reference signal. The valve unit (2) is subjected to a procedure indexing the position of the movable member (3′) and setting parameters for the control means (6) at the beginning of each new operating cycle of the assembly, and the pump (1) is rotated at a constant speed selected from a limited number of predetermined speeds at least during part of each operating cycle.
