Abstract: The present disclosure shows a crankshaft having at least one counterweight that is preferably screwed to the crankshaft via at least two screws, with the counterweight having a contact surface at which it contacts a counter-contact surface of the crankshaft. In this respect, the position of the counterweight at the crankshaft is fixed via at least one positioning element independent of the screw connection.

Abstract: A mixing device for integrating into an exhaust pipe of an internal combustion engine and for intermixing an exhaust gas flow T, which device is formed by a housing including a pipe wall for guiding the exhaust gas in a main flow direction H, an intermediate wall which at least partially delimits a flow cross section Qs of the housing, and by a mixing pipe, wherein: the mixing pipe has an injection nozzle for an additive to be incorporated, the nozzle being in the region of a first end E1 of the mixing pipe, and the mixing pipe is accommodated, in the region of a second end E2, in the intermediate wall; a perforation zone having a through-flow cross section Qp is provided at least between the injection nozzle and the intermediate wall; the intermediate wall and the mixing pipe 5 separate the housing into an inflow sector and an outflow sector; at least 90% of the gas to be guided from the inflow sector to the outflow sector can be directed through the perforation zone; a wedge-shaped flow-directing element ha

Abstract: The invention concerns a cam mechanism (10), in particular for the actuation of ventilation valves of a vehicle ventilation system with a revolving cam disc (12) which has on one of the disc faces two curvilinear guides (16, 18) intersecting in intersection areas (14) as well as two swivelling adjustment levers (20, 22) each with a coupling (24, 26) associated with a curvilinear guide (16, 18). For guiding at least one adjustment lever (20, 22) during its on passage through the intersection areas (14) separate guide elements (32a, 32b, 32c) different from the curvilinear guides (16, 18) and the couplings (24, 26) are provided.
