Abstract: A heating device for heating fluids, such as water or a liquid coolant, for application in electric or hybrid vehicles, where the absence of an internal combustion engine or its shorter time of use requires using heating devices for heating either the passenger compartment or other parts of the vehicle that require it. The heating device is provided with a configuration which limits the temperature to the temperature at which heat exchange occurs between the heat generation source and the liquid to be heated, such that the liquid does not generate precipitates, prolonging the service life of the device.

Abstract: The present invention relates to a heating device for heating fluids, such as water or a liquid coolant, for example, which can be applied in electric or hybrid vehicles, for example, where the absence of an internal combustion engine or its shorter time of use requires using heating devices for heating either the passenger compartment or other parts of the vehicle that require it. The present invention is characterized by a configuration which limits the temperature to the temperature at which heat exchange occurs between the heat generation source and the liquid to be heated, such that the liquid does not generate precipitates, prolonging the service life of the device.

Abstract: The present invention relates to a gas management device suitable for being installed at the outlet o fa particle filter or of a catalytic converter. This device is characterized by a very compact configuration having at least the heat exchanger for an EGR (Exhaust Gas Recirculation) system, particularly suitable for a low pressure system, and an exhaust gas discharge pipe which is part of the exhaust line. According to one embodiment, the device also allows integrating a bypass valve for the EGR heat exchanger. According to another embodiment, the device allows integrating a heat recovery unit participating in the EGR system. According to another embodiment, the device also allows both including a bypass and including a heat recovery unit. The degree of integration with the particle filter of the catalytic converter is maintained in all cases.

Abstract: A by-pass valve to regulate the passage of a gas towards two areas of a device, comprising a body coupled to said device, with an internal chamber in which the inlet gas is received through an inlet pipe, and two outlet pipes directed towards said areas and having a planar face with an access opening to its internal chamber through which there is inserted a planar plate on which the closing member and its actuation means are assembled, the closing member being duly positioned so as to close the outlet pipes.

Abstract: The present invention relates to a three-pass heat exchanger for an EGR system, comprising a casing housing at least one cooling chamber for gas circulating through a plurality of pipes and heads on its ends coupled to the gas inlet pipe coming from the exhaust manifold and to the gas outlet pipe connected to the intake manifold of the engine, which is configured as a three-pass heat exchanger, i.e. with three differentiated areas for gas circulation from the inlet pipe to the outlet pipe, the inlet pipe and the outlet pipe being located at opposite ends of the exchanger. The exchanger can include a bypass valve and two cooling chambers at different temperatures.
