Embodiment Construction

[0056] first reference figure 1 , which shows a circuit 10 for cooling a motor vehicle engine 12 such as a heat engine, an electric motor or a hybrid motor. A cooling fluid, typically water with antifreeze added, is circulated through the circuit 10 by means of a pump 14 . The circuit includes a cooling radiator 16 in which a cooling fluid dissipates heat to an air stream in motion by the speed of the vehicle and / or an engine fan (not shown).

[0057] This circuit comprises a control valve 18 having an inlet 20 connectable to an outlet 22 of the engine, two other outlets 24 and 26 not described in detail, and a radiator outlet 28 connectable to a cooling radiator 16 .

[0058] The outlets 24 and 26 can be connected in a manner known per se, for example to a unit heater for heating the interior and to a bypass duct bypassing the radiator.

[0059] In this type of circuit, the control valve 18 may comprise, for example, a regulating member of the rotary type, making it possibl...

Abstract

The invention relates to a module for the cooling circuit of an engine in an automobile, that comprises at least one control valve (18) allowing a flow according to at least one so-called nominal mode. The module further includes a thermal safety device (30) for said circuit, the thermal safety device (30) being capable of authorising a flow according to another so-called short-circuit mode in case of failure of the nominal flow mode. The invention can be used for automobiles.

Description

technical field [0001] The invention relates to a cooling circuit for motor vehicle engines. [0002] More particularly, it relates to a module for a motor vehicle engine cooling circuit, comprising at least one control valve allowing circulation according to at least one normal mode. Background technique [0003] Usually the cooling fluid is pumped through a cooling circuit of this type comprising a control valve having an inlet connectable to the engine and a radiator outlet connectable to the cooling radiator (see especially 2003 French patent FR 2850726 of January 31). [0004] In this known cooling circuit, the control valve comprises a rotary adjustment member capable of assuming different angular positions to control the distribution of fluid through various outlets, including radiator outlets connectable to cooling radiators, connectable A unit heater outlet to a unit heater for heating the vehicle interior, and a branch outlet connectable to a diversion that bypas...
