Abstract: A sealing system, in particular for sealing multiple part exhaust-gas lines for an internal combustion engine, has at least a first flange part (9) and a second flange part (11) guiding a flow of heat (5). The flange parts (9, 11) delimit a receiving space (33) for at least one sealing element (31) between them and adjoin one another. Each flange part forms an outwardly projecting annular flange (13) facing away from the flow of heat (5), and extending transversely with respect to the heat flow. Chambering of the receiving space (33) is formed for the sealing element (31) by an annular groove (45) open at the end face (17) of at least one flange part (11) and recessed axially into said end face (17). At least one covering element (47) is arranged in the annular groove (45) and provides thermal shielding for the sealing element (31) at least on its side facing the end face (17) of the flange part (11).

Abstract: In a sealing arrangement, in particular for the connection of a manifold to a cylinder head of an internal combustion engine, a flat support (1, 3) has at least one sealing element in the form of a ring element (17) that forms a mold seal. The support (1, 3) and ring element (17) form a unit that holds the ring element captively on the support (1, 3).

Abstract: A sealing system, in particular for attachment connections on flow paths for hot gases, such as exhaust gas flows from internal combustion engines, with a sealing support (3) and at least one sealing element (1) that defines a sealing plane that is located between sealing surfaces, characterized in that the sealing support (3), as a separate component, is separated from the sealing element (1) as another separate component, and in that the two components are captively connected to one another to preserve the sealing system.

Abstract: A sealing system, in particular for sealing multi-part exhaust gas pipes for an internal combustion engine, with at least a first flange part (9) and a second flange part (11) that guide a heat flow (5) and that border between them a receiving space (33) for at least one sealing element (29, 31), is characterized in that the flange parts (9, 11) that are adjacent to one another in each case form a ring flange (13) that extends outward, facing away from the heat flow (5) and running transversely to the latter, in which the faces (15, 17) of the flange parts (9, 11) that are adjacent to one another form a chamber to some extent of the receiving space (33) of the sealing element (29, 31).

Abstract: A sealing arrangement, in particular for pipe connections to the exhaust gas system of an internal combustion engine, with a sealing support and at least one sealing element in the form of a ring element (25) that forms a mold seal, is characterized in that a holding device (27) that produces a frictional connection between sealing support and ring element (25) is provided to secure the latter captively to the sealing support.

Abstract: A plate heat exchanger includes a plurality of spaced plates secured together to form a stack having a plurality of fluid flow channels and a first plurality of passages. The channels are divided into at least first and second groups, the channels in the first group spaced from one another by the channels in second group. Each passage in the first plurality of passages extends between adjacent plates through one of the channels in the second group of channels. Each successive passage in the first plurality of passages is in fluid communication with successive channels in the first group of channels, and is offset from each preceding passage in the first plurality of passages such that fluid flowing through the first group of channels and the first plurality of passages follows a serpentine pattern through the stack.
