Abstract: A hydraulic trim device is provided for a boat motor with at least one trimming cylinder, a piston rod movable axially in the trimming cylinder between a first end position and a second end position, a trimming plate and a hydraulic unit. The trimming cylinder can be pressurized via the hydraulic unit to extend the piston rod. The piston rod has a contact portion and the trimming plate has an contact surface and the contact portion is in contact with the contact surface. The contact portion moves along the contact surface when the piston rod moves between the first end position and the second end position relative to the contact surface. The contact surface at least partially has a convex curvature in the direction of the piston rod. A boat motor with a hydraulic trim device and to a boat with such a boat motor are also provided.

Abstract: A boat drive hydraulic steering unit has a steering cylinder unit, pump and tank. The cylinder unit has a first chamber, piston and second chamber. The pump is connected to the first and second chambers by respective first and second line. The first chamber is connected to the tank via the first line arrangement when the second chamber is pressurized, by the first line arrangement having a first check valve which opens when the second line arrangement is pressurized. The second chamber is connected to the tank via the second line arrangement when the first chamber is pressurized, by the second line arrangement having a second check valve which opens when the first line arrangement is pressurized. The first and second line arrangements have respective first and second throttling devices acting in the direction of flow towards the tank. A boat drive may include the steering unit.

Abstract: A module for insertion into a data carrier body to form a data carrier, the module having a contact interface with a contact area, at least one integrated circuit and a display device with a display area which are interconnected. Method for producing the module, the data carrier body and the data carrier. The contact interface and the display device of the module are disposable in the data carrier body such that the contact area of the contact interface and the display area of the display device point in opposite directions. The data carrier body thus possesses a through opening into which the module is insertable as described.

Abstract: The invention relates to a module (10) for insertion into a data carrier body (110), the module (10) comprising a contact interface (20) with a contact area (22), at least one integrated circuit (30, 30?, 30?) and a display device (40) with a display area (42) which are interconnected, and to the data carrier body (110) and to a data carrier (100) comprising the data carrier body (110) with the inserted module (10). The invention relates further to methods for producing the module (10), the data carrier body (110) and the data carrier (100). The contact interface (20) and the display device (40) of the module (10) are disposable in the data carrier body (110) such that the contact area (22) of the contact interface (20) and the display area (42) of the display device (40) point in opposite directions. The data carrier body (110) thus possesses a through opening (120) into which the module (10) is insertable as described.
