Abstract:
A pneumatic pressure regulating valve, the opening of which can be automatically changed in a pressure-related manner, including a control diaphragm that is subjected to a reference pressure, to the gas pressure as well as to a governor spring, wherein a change in the differential pressure causes an adjustment of the control diaphragm and the latter itself or a closing element actuated by it changes the opening through an outflow cross-section, and wherein a structure that is arranged adjacent to the outflow cross-section on the diaphragm side forms a stop for the control diaphragm or for the closing element in the closed position of said control diaphragm. At least one preliminary stop is arranged in the pressure regulating valve such that, when the control diaphragm is moving in its closing direction, the control diaphragm or the closing element first comes into contact with the preliminary stop and that, when the control diaphragm is moving further in its closing direction, the control diaphragm or the closing element will then, while being subjected to elastic and flexible deformation or being further subjected to elastic and flexible deformation respectively, further reduces the opening and, in a final position, also comes into contact with the stop.

Abstract:
A rotor for a centrifuge (1), wherein the rotor is rotatably driven about a rotation axis and includes two parts, i.e., a central bearing part and a waste collecting part which is provided with a waste collecting area. The waste collecting part is separable from the bearing part for waste disposal or cleaning. The bearing part and waste collecting part are provided with torque transmitting surfaces which interact with each other in a form-fitting and/or adherence manner and are connectable by axially positioning the waste collecting part on the bearing part and disconnectable by axially removing the waste collecting part from the bearing part. The rotor is formed such that the circumferences of the bearing part and the waste collecting part are connectable in a form-fitting manner and arranged in such a way that the waste collecting part circumference is placed or rests on the corresponding circumference of the bearing part already at the initial state of the waste collecting part or as result of the radial expansion thereof produced by a centrifugal force and/or by heating.

Abstract:
A tank venting device for motor vehicles having a fuel tank, an adsorption filter connected thereto that receives the fuel vapors, an air inlet valve, and a regeneration line to the engine in which an air delivery pump is arranged. A regeneration valve controlled by the engine is provided in the regeneration line before the air delivery pump in order to control the regeneration flow rate.
Abstract:
An input component (3) of a clutch is fastened to the output end (5) of the crankshaft (7) of an internal combustion engine by a force-fit coupling (11) in which a radial force fit is produced by axial forces which are applied to the coupling (11) by a tool inserted through the hub (21) of a clutch disc (23) or applied to the hub, which in turn applies the axial force on the coupling. The coupling enables the clutch (1), including the flywheel (3) and the clutch disc (23), to be installed on the crankshaft (7) as an assembled unit. The force-fit coupling (11) comprises an expanding conical, element (61), arranged in a central opening (59) of the output end (5) of the crankshaft (7), which expands the output end (5) of the crankshaft radially.
