Abstract: An oil decantation system for an internal combustion engine includes at least one main wall provided with a through-opening for a flow of blow-by gas and a separator device arranged downstream of said through-opening in the direction of travel of said flow of blow-by gas. The separator device includes a valve provided with a decantation component capable of retaining the oil contained in the blow-by gas and of allowing a flow of purified blow-by gas to pass through, wherein the valve is pivotably mounted on the main wall so that its inclination with respect to the main wall varies as a function of the flow of blow-by gas.

Abstract: A thermostatic valve includes a hollow body, two openings opening into the body and being hydraulically connected by a pass section, and a shut-off component arranged partially in the pass section and having a thermostatic actuator, a return component, a valve capable of opening the first opening when actuated by the thermostatic actuator and of closing the first opening when returned by the return component. The thermostatic actuator includes a cylinder containing an expansion material and a stem defining an axial direction. A relative movement between the cylinder and the stem along the axial direction occurs under the action of the expansion material. The stem bears at an ends against an abutment element, which is movable under the action of movement component in the direction of the cylinder to allow the opening of the first opening when the temperature of the expansion material is below the threshold temperature.

Abstract: A heat exchanger including a stack of plates spaced apart in such a way as to present an assembly of intermediate spaces allowing a fluid circulation between the plates. The assembly of intermediate spaces including a plurality of intermediate multi-fluid spaces each intended for circulation of a plurality of fluids between two adjacent plates, and each partitioned into a plurality of compartments separated from each other in a sealed manner. Each compartment is configured for the circulation of one fluid from the plurality of fluids, and is in fluid communication with one of the compartments of a distinct intermediate multi-fluid space.

Abstract: This air distributor (1) has an exterior casing defining an interior volume, an air inlet (4) opening into this interior volume, several air outlets (4) intended to convey air from the interior volume towards the cylinders of an engine, and a heat exchanger (8) arranged in the interior volume. The heat exchanger (8) comprises a stack of plates (10) of plastic material where adjacent plates (10) are arranged so as to define a set of intermediate spaces comprising closed intermediate spaces (12) in fluid communication to enable circulation of fluid through the stack of plates (10), and open intermediate spaces (14) configured to enable a passage of air through the stack of plates (10) from the air inlet (4) to the air outlets (6).

Abstract: This heat exchanger (1) comprises a stack of plates (2) spaced apart in such a way as to present an assembly of intermediate spaces (4) allowing a fluid circulation between the plates (2). Further, the assembly of intermediate spaces (4) comprises a plurality of intermediate multi-fluid spaces (40) each intended for circulation of a plurality of fluids between two adjacent plates (2), and each partitioned into a plurality of compartments (42) separated from each other in a sealed manner. Each compartment (42) is configured for the circulation of one fluid from the plurality of fluids, and is in fluid communication with one of the compartments (42) of a distinct intermediate multi-fluid space (40).

Abstract: The invention relates to a device (1) for an engine which includes an oil pan (2) made of a plastic material having a hollow shape (21) containing lubricating oil defined by a bottom wall (22), a plurality of side walls (24) and upper edges (25). The oil pan (2) has at least one exchanger surface (30) which comprises means for circulating oil and means for circulating a coolant, and a heat exchanger (4) in which oil and a coolant circulate, comprising a series of plates (41) made of a plastic material welded together two-by-two and welded to the exchanger surface (30).
