Disclosed is a tube configured to conduct a fluid flowing through the tube in a specified flow direction and for this purpose comprises a tube wall, which encloses a lumen of the tube, and an interference body, which is arranged within the tube but is nevertheless connected to the tube wall at an inner face of the tube wall facing the lumen. In the tube according to the present disclosure, the tube wall has a maximum wall thickness of more than 1 mm and at least two mutually spaced sub-segments with a respective wall thickness that deviates from said maximum wall thickness, wherein the sub-segment is positioned upstream of the interference body in the flow direction, and the sub-segment is positioned downstream of the sub-segment in the flow direction.

A tube fitting and a tube fitting enabling a configuration that limits a through-flow rate of fluid that has passed through a flow aperture opened by a valve unit are obtained. An upstream-side choke hole in an upstream-side choke section limits the through-flow rate of the fluid. In a case in which the fluid flows at a flow rate exceeding the through-flow rate limited by the upstream-side choke hole, the valve unit opens the closed flows aperture in a flow path. A downstream-side choke hole in a downstream-side choke section disposed at a downstream side of the valve unit limits the through-flow rate of fluid that has passed through the flow aperture.

An apparatus and method for personalized product modification is disclosed. The personalized product modification may be applied to various different types of vehicle components. For example, a lid covering may be placed on the top exterior portion of a particular vehicle component, such as an air intake system. The lid may have certain structural characteristics which provide for aesthetic features, such as colors or various other designs, to be subject to varying degrees of user customization. On the underside of the lid covering may be additional customizable components which provide for even greater user customization of the aesthetic appearance of various vehicle components. For example, various colors and designs may be placed on the exterior of the vehicle component, with the lid acting so as to safely and securely cover the customizable components.

An extraction device for a heating tracer includes a clamping assembly and a driving member. The clamping assembly includes a connecting seat, a first extrusion wheel and a second extrusion wheel rotatably arranged on the connecting seat. The first extrusion wheel and the second extrusion wheel are both an eccentric wheel. In use, the heating tracer is clamped between the first extrusion wheel and the second extrusion wheel, and is in contact with an outer circumference of the first extrusion wheel and the second extrusion wheel. The driving member includes a main body and a drive shaft arranged thereon. The main body is configured to drive the drive shaft to extend along an axial direction of the main body. The drive shaft is connected to an end of the connecting seat away from the first extrusion wheel and the second extrusion wheel.
