Abstract: A throttle body comprising a main body defining a cylindrical intake air channel and including a valve member movable between an open and a fully closed position. The valve seal surface and a contact surface are configured such that the valve seal surface sealingly contacts with the corresponding contact surface when a fully closed position of the valve has been displaced due to contraction of one of the main body and the valve member. The valve seal surface and the contact surface of the valve member in the fully closed position are inclined by an angle. The contact angle of inclination gradually decreases from a first point located on a circumference of the periphery of the valve member resulting from a line perpendicular to an intersection of the central axis and the rotation axis to a second point that is proximate to the rotation axis of the valve member.

Abstract: A sewing thread made of synthetic fibers is described, whereby the ready-to-use sewing thread has an elongation at break between 25% and 85% and an elastic tensile elongation of between 30% and 95% of the elongation, determined by a measuring strength, corresponding to 70% of the absolute strength of the respective sewing thread. In addition, two methods for making a sewing thread are also described, whereby the sewing thread comprises either a plied yarn or an air-intermingled sewing thread. To produce this sewing thread yarn components with an elongation at break between 25% and 85% and an elastic tensile elongation of between 30% and 95% are selected, whereby thermal and preferably hydrothermal treatment is carried out after the actual yarn production.
