Abstract: The disclosure relates to a roller tappet for a high-pressure fuel pump. The roller tappet includes a housing that accommodates a cam contact roller next to a drive-side annular face of the housing. A bridge piece sits on an inner lateral surface of the housing, after the cam contact roller, as viewed from the drive-side annular face. An outer end face of the bridge piece has a rest for a pump piston. A separate adapter bolt protrudes from the rest beyond the output-side annular face of the housing; an end face of the adapter bolt, remote from the bridge piece, serves as a direct rest for the pump piston. An annular disc sits next to the output-side annular face of the housing, and the bore of said annular disc surrounds and retains the adapter bolt.

Abstract: A mobile handwashing system (1) includes a freestanding supply station (2) and at least one freestanding handwashing station (3). The supply station (2) includes a freshwater tank (4), which is fluidly connected or connectable to the at least one handwashing station (3) via a first freshwater supply line (5) and is fluidly connected or connectable to a freshwater supply system via a second freshwater supply line (6). The supply station (2) includes a wastewater or graywater tank (7) and/or a wastewater pump (23) which is fluidly connected or connectable to the at least one handwashing station (3) via a first wastewater line (8) and is fluidly connected or connectable to a wastewater disposal or wastewater treatment system via a second wastewater line (9).

Abstract: A pivot bearing (1) for a hydraulic clearance compensation element (2), especially of a valve train of an internal combustion engine, is provided in which the pivot bearing (1) has a first part (3) projecting in an axial direction (a) with a surface (4) that is convex at least in some sections and also a second part (5) with a surface (6) that is concave at least in some sections for at least partially holding the first part (3). To optimize the production of such a pivot bearing and to minimize the associated costs, the invention provides that the first part (3) is constructed at least partially as a ball, wherein the second part (5) surrounds the ball (3) with undercut in the axial direction (a).

Abstract: A transmission element in the form of a rocker arm (1) or swinging arm for a reciprocating piston internal combustion engine is provided that can be actuated on one side by a cam of a camshaft and on the other side is in active connection with at least one gas exchange valve directly or via an intermediate arrangement of a valve bridge. The transmission element has a hydraulic valve lash compensation element, also called “HVA”, and the hydraulic valve lash compensation element is arranged at a force transmission end of and attached to the transmission element.

Abstract: A valve train for a reciprocating piston internal combustion engine with a transmission element in the form of a rocker arm (1) or pivot arm that can be actuated, on one hand, at least indirectly by a cam of a camshaft and is in active connection, on the other hand, through an intermediate connection of a valve bridge (4), with gas-exchange valves (7, 8). The valve bridge (4) has hydraulic valve lash compensation elements (“HVAs”) allocated to each gas-exchange valve (7, 8).
