Abstract: The present disclosure relates to a clutch system having a clutch device and a fluid actuating device to engage and/or disengage the clutch device, the clutch device having at least one counter-pressure plate, at least one clutch cover with at least one diaphragm spring pivotably supported on the clutch cover at a swivel radius, and at least one contact plate which is movable in the axial direction of the clutch device by the diaphragm spring to frictionally clamp a clutch disk between the contact plate and the counter-pressure plate, wherein the diaphragm spring acts on the contact plate at an effective radius located outside the swivel radius in the radial direction of the clutch device and is actuatable at an actuation radius located inside the swivel radius in the radial direction by the actuating device.

Abstract: A hydraulic system includes a master cylinder having a housing, a piston axially movably disposed in the housing, and a piston rod, the piston bounding a pressure chamber filled with a hydraulic fluid, the piston upon actuation of the master cylinder being axially moved by the piston rod to pressurize the hydraulic fluid; an actuating device for moving the piston rod; a slave cylinder; a pressure-medium line connecting the master cylinder and slave cylinder; and at least one damping element arranged between the actuating device and the slave cylinder.

Abstract: An apparatus for detection of the accuracy of format of a web of corrugated cardboard moved in a conveying direction comprises a light source which emits a light band to the surface of the web of corrugated cardboard in a direction crosswise of the conveying direction and at an angle to the web of corrugated cardboard. A measuring camera detects the different light intensities of the light reflected by the plane portions and the profiled patterns of the web of corrugated cardboard. This electronic image in the camera is evaluated by an evaluation device for determining the distance of the profiled patterns from each other.

Abstract: A hydraulic actuation system, especially for actuating the clutch of a vehicle, containing a master cylinder unit, a slave cylinder unit, a hydraulic medium line connecting the two cylinder units and a throttle valve which is used to alter the flow resistance between the cylinders of the master cylinder unit and the slave cylinder unit.

Abstract: A hydraulic system, in particular for motor vehicles, including a master cylinder having a housing and a ring piston that is axially displaceable in it and is sealed against this housing, and a pressure medium outlet, as well as a slave cylinder having a housing and a ring piston that is axially displaceable in it and is sealed against this housing, and a pressure medium inlet, as well as a pressure medium line that connects the pressure medium inlet and the pressure medium outlet in a hydraulically effective way, where these parts and their components have specific individual rigidities; this total rigidity or base rigidity C0 of the hydraulic system is increased through the use of pistons for master cylinders having an area of 300 mm2-1000 mm2 and through the use of ring pistons for a slave cylinder having an area of 800 mm2-2500 mm2.

Abstract: The present invention relates to a hydraulic system, in particular for motor vehicles, including a master cylinder having a housing, a piston which is axially movably disposed therein, which bounds a pressure chamber filled with a hydraulic fluid, and which, upon actuation of the master cylinder, is axially moved by a piston rod acting upon the piston, thereby pressurizing the hydraulic fluid; further including a slave cylinder and a pressure-medium line connecting the cylinders; the master cylinder having an adapter for detachable connection to the pressure-medium line. The objective of improving the connection between the pressure-medium line and the adapter is achieved in that the adapter includes a sleeve made of a metal.
