Abstract: A fuel cell system is provided having a fuel cell and a jet pump control valve unit connected to an anode chamber with an intake connection and a pressure connection. A fuel gas control valve connecting a fuel gas source and the jet pump has a valve seat with a first sealing surface and at least two through-flow channels, and a moveable valve body with a second sealing surface. The valve body can be moved into a blocking position and a through-flow position using a valve body actuator. The sealing surfaces rest on one another in a common sealing plane and form a seal in the blocking position. A stroke gap is formed between the sealing surfaces in the through-flow position. The first or second sealing surface is arranged on a raised sealing level. A volume flow of a drive jet can be controlled by the valve body actuator.

Abstract: A sliding sleeve for a synchronous manual transmission assembly is produced by the following steps: a tubular blank is provided in which an internal toothing arrangement is present, and the blank which is provided with the internal toothing arrangement is further processed to form a plurality of sliding sleeves.

Abstract: The invention relates to a winding arrangement for an electric machine with a polyphase winding, in which a plurality of coils or coil groups connected in parallel (50, 52, 54, 56) are connected with a conductor rail (40, 42, 44, 46). This makes it possible to connect the coil ends directly and without connecting pieces with the electric power supply. The conductor rails (40, 42, 44, 46) are preferably arranged at one or both face sides of the post of the electric machine below the slot openings, i.e., in the area of the back of the post. Furthermore, the invention is aimed at an corresponding manufacturing method for a winding arrangement of a polyphase winding for an electric machine, in which the coils or coil groups connected in parallel (50, 52, 54, 56) of the winding are connected with one of the conductor rails (40, 42, 44, 46).

Abstract: The invention concerns a winding for a post or an armature of an electric machine with a post or armature (32) with slots (34) composed at least in part of L-shaped structural parts (1, 2, 3). In doing so, one leg of an L-shaped structural part each time creates a slot bar (8a, 8b) located in a slot, and the other leg creates a connecting line (6a, 6b) located at a face of the post or armature. Moreover, the invention concerns a winding with several interlaced coils (50, 52, 50?, 52?, 50?, 52?) whereby the connecting lines (6) of interlaced coils (50, 52, 52?, 50?, 52?) are staggered and therefore arranged in layers. The invention furthermore concerns a winding with connecting lines (6) flatter than the slot bars (8), styled as a fractional pitched polyphase winding with two slots per pole and branch.

Abstract: The invention relates to a winding arrangement for an electric machine with a polyphase winding, in which a plurality of coils or coil groups connected in parallel (50, 52, 54, 56) are connected with a rotating conductor rail (40, 42, 44, 46). This makes it possible to connect the coil ends directly and without connecting pieces with the electric power supply. The conductor rails (40, 42, 44, 46) are preferably arranged at one or both face sides of the stator of the electric machine below the slot openings, i.e., in the area of the back of the stator.
