A high-pressure fuel pump has an inlet valve and a pressure-limiting valve which fluidically connects a high-pressure region to an inlet valve region located, in terms of geometry, between the inlet valve and an electromagnetic actuator of the high-pressure fuel pump, which acts upon the inlet valve via a tappet.

A gear machine comprises a housing, at least two gearwheels positioned within the housing, and a bearing body defining a circular-cylindrical outer surface segment and a bearing bore. The at least two gearwheels configured to mesh in external engagement with each other. At least one of the gearwheels includes at least one bearing journal rotatably positioned within the bearing bore. The bearing body is positioned within the housing with the circular-cylindrical outer surface segment engaging a corresponding bearing surface defined on the inside of the housing. Each of the at least two gearwheels includes a plurality of tooth tips configured to engage a corresponding sealing surface defined on the inside of the housing. At least one segment of at least one of the sealing surface and the bearing bore is eccentric with respect to the circular-cylindrical outer surface segment of the bearing body. A method of production is also provided.

A toothed wheel machine including a housing for receiving two meshing and especially helical-toothed wheels. The toothed wheels are axially mounted in a sliding manner by axial surfaces between bearing bodies received in the housing, and radially by a bearing shaft received in the bearing bodies. During the operation of the toothed wheel machine, an axial component of a force resulting from the hydraulic and mechanical forces generated during operation acts on each toothed wheel in the same axial direction. A counter-force against the respective axial force component is applied to the toothed wheels and/or bearing shafts, each counter-force applying the same amount of pressure as the respective axial force component, or less than same.

A workpiece carrier ( ) for conveying one or more workpieces with a belt conveyor ( ) is described, which reduces the production cycle time of an industrial manufacturing plant. The workpiece carrier ( ) includes energy storage devices ( ), into which energy of motion of the workpiece carrier ( ) is transferred when the workpiece carrier is braked against or stopped on the belt conveyor ( ). The energy storage devices each include a coupling element ( ), advantageously a friction wheel or contacting piece , urged into continuous contact with the conveyor belt, and a spring device, advantageously a spiral spring or a coil spring , connected with the friction wheel and put under tension when the workpiece carrier ( ) is braked. If the workpiece carrier is no longer braked or stopped, the spring device is released and delivers stored energy by driving the friction wheel or contacting piece, where by the workpiece carrier ( ) is additionally accelerated.

Workpiece carrier, especially for a belt conveyor

A pulsation damper for hydraulic circuits has a housing including a bottom, a casing, and a cover, a damper chamber which is sealed from outside and provided with supply and discharge means for a pressure medium, the housing being composed of two parts so that the bottom and the cover are connected with one another to form a single central element, while the casing peripherally surrounds the central element, the central element, and means forming force-free connecting points between the central element and the cover.
