摘要： A piston with a cooling channel having a basic piston barrel made from forged steel and a box-shaped shaft, bosses and boss supports and connecting walls between the boss supports as well as a combustion trough. The piston increases the rigidity of the ring part. To accomplish this, the piston has a wall extending all around above the boss bores. A structural component is welded in between the wall and the piston head and limits the cooling channel. This design increases the rigidity of the ring part in pistons.

摘要： A piston for an internal combustion engine has a piston head that has a circumferential cooling channel as well as a combustion bowl having a circumferential bowl wall that makes a transition into a piston crown by way of a bowl edge region. The combustion bowl is formed at least in part by a piston base body and the bowl wall is formed at least in part from an insert. The insert is connected with the piston base body by means of beam welding. A lower weld seam is configured in the bowl wall, which seam encloses an acute angle with the piston center axis (M) and ends in the lower half of the cooling channel. An upper weld seam runs from the cooling channel ceiling to the piston crown and is disposed centered or radially offset toward the outside, with reference to the clear width of the cooling channel.

摘要： A piston for an internal combustion engine with a separate head and skirt which are joined by a piston pin. The ring belt extends downward from head and terminates above the pin. The space between the lower edge of the ring belt and a section of the head defines a cooling oil ring space. A depression is formed in the head and is partly defined by the section. The second land has the largest diameter and exclusively guides the piston. The height of the second land is in the range of three to seven percent of the piston diameter. The diametrical second land clearance is 1.5% to 2.5%. The diametrical third land clearance is one percent of the piston diameter. The diametrical top land clearance is in the range of 1.5 mm to 2.0 mm.

摘要： In order to be able to supply a rotating transfer roller in a transfer printing station of an electrophotographic printing device with a high voltage, a system and method is proposed that comprises a voltage transfer device with an elastically borne brush, a compensation device with a bushing standing under spring force, and a monitoring device with a Hall switch. For voltage transfer, the brush is pressed onto the voltage connection location of the transfer roller. For compensation of the axial play of the transfer roller, the bushing is pressed onto the bearing of the transfer roller. For monitoring as to whether a transfer roller is connected with the device, the Hall switch is used which checks whether the bushing has been moved or not.

摘要： A piston for an internal combustion engine has an upper part and a lower part. The upper part has a collar with a ring rib and the lower part has a wall and a contact part radially within the wall. When the upper part is connected with the lower part by friction welding, the face surfaces of the ring rib, the collar, the wall, and the contact part form friction-welding surfaces and form a cooling channel and a cooling cavity between them. To supply the cooling channel and the cooling cavity with cooling oil, radial bores are introduced into the ring rib, which bores connect the cooling channel with the cooling cavity. In this way, it is guaranteed that a sufficient residual amount of oil collects in the cooling channel and in the cooling cavity, which amount is constantly renewed, and leads to good cooling of the piston crown.
