Abstract: A line connector assembly and a line connector for fluidically connecting fluid lines is described. A housing has: a receiving space; a connecting piece; and a channel through which fluid can flow. The channel through which fluid can flow has a first straight channel portion and a curved channel portion. The curved channel portion directly adjoins the first straight channel portion in such a way that fluid can flow through, and the curved channel portion can be connected to a second straight channel portion in such a way that fluid can flow through. The curved channel portion has an inner channel line and an outer channel line, the outer channel being less strongly curved than the inner channel line. The outer channel line of the curved channel portion has, over an entire extent of the curved channel portion, a length (L).

Abstract: The disclosure relates to an insert piece for inserting into a channel section of an angled piece for fluidically connecting fluid lines. The insert piece has a mounting for placing on the channel section and at least one guide element for at least partly changing the flow direction of at least one part of a fluid flowing through the channel section by a change angle. The mounting has an opening, and the at least one guide element is arranged in the opening. The guide element extends between a first section of the mounting and a second section of the mounting and is secured to the mounting. The mounting has a recess between the first section and the second section.

Abstract: An angle piece for fluidically connecting fluid lines of a vehicle. The angle piece has a channel portion for altering a flow direction of a fluid about an alteration angle. An input flow direction of the fluid into the angle piece and an outlet flow direction of the fluid from the angle piece form limbs of the alteration angle. At least one guide element is arranged in the channel portion, which guide element protrudes into the channel portion. The at least one guide element altering the flow direction of a part of the fluid by the alteration angle. The angle piece thus has a low pressure drop.

Abstract: A filter module (1) for cleaning a fluid, including a housing (2) with an inlet opening (3) and an outlet opening (4), wherein the housing (2) forms an accommodation space (5) in which at least one filter element (6) is accommodated, wherein the filter element (6) exhibits a filter medium (7) which is configured like a block in view of the problem of configuring a filter model such that the dead space in the housing is as small as possible, that the filter module has good filter performance and a cost-effective as well as time-saving fabrication and offers effective use of a filter medium, characterized in that the filter medium (7) is pleated and is telescoped into a block (8).

Abstract: A replaceable filter module is configured to be flanged to a wall of a housing that holds a fuel cell. The filter module includes a filter element with a filter medium and at least one of a seal and sealing elements. The seal includes one of a key-and-lock connection, a plug-and-socket connection, and a tongue-and-groove connection.
