20110265587 | Drive cartridge - The invention relates to a drive cartridge comprising an actuating mechanism, in which a spindle can be guided in a hollow cylindrical drive element between two end positions at an axial distance from one another, said positions being defined by the axial length of the drive element, and to a dome-shaped casing that surrounds the drive element in a non-rotatable and non-displaceable manner. The cartridge is characterized in that the drive element has an external contour with an eccentric profile and in that the internal contour of the dome-shaped casing has a positive fit only in those areas of the drive element in which the permissible normal stress exceeds a predefined upper limit. | 11-03-2011 |
20100284766 | CENTERING PIN - A receiving element which can be introduced into a borehole of at least one component includes a bolt presenting an outer surface that is approximately parallel and advantageously coaxial to a longitudinal axis of the bolt. The receiving element requires few materials and can therefore be produced at a low constructional cost while being provided with high dimensional stability and positioning accuracy. The bold includes an abrasion-resistant sintered material, and a metal tip provided on the front end of the shaft. The end part of the tip is engageable in a recess of the bolt, and there is a direct connection between the end part and the recess in the connection region on the front end of the bolt. | 11-11-2010 |
20090294718 | SHUT-OFF DEVICE - The invention relates to a shut-off device comprising a housing which is to be connected to an adjacent conduit in a pressure-tight manner A tubular passage is defined in the housing for a medium flowing through the conduit. Said device also comprises at least one sealing body which can be displaced by an articulated mechanism, by means of an adjusting drive that can be moved vertically in relation to the direction of flow, from an open position into a closed position in which the sealing contour of the at least one sealing body comes into contact with the tubular passage in a radially sealing manner. The articulated mechanism is guided parallel to the direction of displacement of the adjusting drive and comprises a bearing body to which the at least one sealing body is pivotably applied. The inventive shut-off device is characterized in that the bearing body comprises two diametrically opposed ribs and two corresponding grooves are formed in the wall of the housing or in an insert at least partially lining the housing, the ribs forming a span extending transversally to the direction of flow of the medium. | 12-03-2009 |
