The hydrogen storage element for a hydrogen store comprises a pressed article (1) having a hydrogen-storing first material (2) and having a thermally conductive second material (3), wherein the second material (3) is in thermal contact with the hydrogen-storing first material (2) and has, in some regions, a different three-dimensional distribution within the pressed article (1).


The invention relates to a press for producing dimensionally stable preforms (46) from material that is substantially in the form of a powder, in particular iron powder and or ceramic powder, with a tool comprising an upper die and a lower die, wherein the upper die and the lower die respectively comprise at least one die (34, 34a, 34b, 34c, 34d, 34e, 34f, 34g, 48a, 48b, 48c, 48d, 58), wherein a first die and a second die are arranged together, one sliding in the other, as the upper die or lower die and respectively have a first end and a second end, lying opposite the first end, wherein at least one of the two dies spreads out along one portion to such an extent that the second end thereof has a width that at least approaches an outer diameter of a die holder associated with the second end. This allows presses of a compact form to be made available for producing dimensionally stable preforms of high quality and great complexity.


The invention relates to a variable camshaft adjuster (VVT) for an internal combustion engine, comprising a VVT component (1), preferably a locking disc, made of a material made from powder metal, with a locking bore (2) which extends from a first surface (4) of the VVT component (1), preferably the locking disc, into the VVT component. A locking pin of a variable valve control means engages into the locking bore (2), and the locking bore has a connected oil channel (3) which likewise extends from the first surface (4) into the VVT component (1) and opens radially into the locking bore (2). A base (6) of the locking bore (6) has an elevation (7), preferably in the form of an elevated step, which is used as a bearing surface of the locking pin, and the oil channel has a depth which is shallower than that of the locking bore (2). The invention further relates to a VVT component, in particular a locking disc, and to a method for producing the locking disc or the camshaft adjuster.


The invention relates to a method for producing at least one gear, in particular a helically toothed gear, wherein the gear is produced from a gear blank (20, 38, 50, 52, 62, 72, 80, 82, 84) pressed and sintered with an oversize in the region of the set of teeth (18), wherein the gear blank (20, 38, 50, 52, 62, 72, 80, 82, 84) has two opposite end faces and a circumference. In the method, the gear blank (20, 38, 50, 52, 62, 72, 80, 82, 84) is clamped in a clamping means (42). The gear blank (20, 38, 50, 52, 62, 72, 80, 82, 84) is compressed in the region of the oversize by means of the engagement of at least one circumferential tool (10, 28) having a set of mating teeth (12, 26) that engages with the set of teeth (18) of the gear blank (20, 38, 50, 52, 62, 72, 80, 82, 84), wherein the gear blank (20, 38, 50, 52, 62, 72, 80, 82, 84) is radially clamped over the circumference by the clamping means (42) at both end faces during the compression of the gear blank, wherein each individual tooth (56, 66) of the set of teeth (18) of the gear blank (20, 38, 50, 52, 62, 72, 80, 82, 84) is supported by the clamping means (42) substantially over the entire tooth height. In this way, the quality of the set of teeth can be improved. The invention further relates to a device and to a clamping means.


The present invention concerns a hydrogen store comprising a composite material including a hydrogenable material, a method for producing the hydrogen store and a device for producing the hydrogen store.


The present invention concerns a hydrogen store comprising a hydrogenable material, and a method for producing a hydrogen store.


The present invention relates to a pressing device comprising a device for filling a mould of the pressing device with at least two different materials, a cavity (112) which is to be filled with the at least two materials (124, 126, 128), and a filling device (120) for discharging the at least two materials (124, 126, 128) in order to be able to introduce said materials (124, 126, 128) into different areas of the cavity (112). Said filling device (120) comprises at least two separate chambers (130, 132, 134) or at least two chamber areas of a common chamber for simultaneously feeding the at least two materials (124, 126, 128), directly adjacent to each other or spatially separate from each other, for introducing the same into the cavity (112) as layers which are at least partially different from each other and with a relative rotational movement between the filling device (120) and the cavity (112).

A bearing cap in which each foot includes a protrusion formed thereon that is generally linear having opposing sides in which each of these opposing sides support a plurality of crush ribs.


A method of forming a composite component having a brass or bronze powder metal portion sinter fit into a supporting, ferrous portion.


A valve component includes a first disk-shaped joining part and a second disk-shaped joining part. The first disk-shaped joining part has a first opening and has an elevation in a first region of the first disk-shaped joining part which runs at least partially peripherially around the first opening. The second disk-shaped joining part is joined to the first disk-shaped joining part and has a second opening which together with the first opening defines a channel for flow of a fluid medium therethrough. The second disk-shaped joining part further has a depression in a second region of the second disk-shaped joining part which runs at least partially peripherially around the second opening and which opposes the first region of the first disk-shaped joining part. The elevation interacts with the depression in sealing fashion.
