Patent number: 6655331Abstract: A piston-type internal-combustion engine having deactivatable, mechanically actuated cylinder valves that are respectively actuated by at least one camshaft via a roller drag lever (5) comprising two partial levers (5.1, 5.2) that are hinged to one another via an articulated shaft (6), on which the roller (7) associated with a cam (8) of the camshaft is rotatably seated. A locking mechanism (13) is provided to selectively couple or decouple the two partial levers (5.1, 5.2) to activate or deactivate the force transmission between the camshaft and the cylinder valve. The free end 5.11 of one partial lever (5.1) is supported on the cylinder valve (2), and the free end 5.21 of the other partial lever (5.2) is supported on the engine block (11).Type: GrantFiled: February 10, 2003Date of Patent: December 2, 2003Assignee: FEV Motorentechnik GmbHInventors: Markus Duesmann, Joachim Hahn

Patent number: 6544053Abstract: The invention relates to a plug connector arrangement with a two-part mating halves (1, 29), in which a first mating half (1) can be joined to a second mating half (29) via a plug-in control (7). The plug-in control (7) has a lever arm (2) pivotally mounted on a mating half (1) that controls a gearing region (9, 36, 37), forcibly actuating the mating halves (1, 29). The lever arm (2) is provided on one side on the mating half (1) and in addition to its pivot movement (8) is mounted via a pivot support (10) on the mating half (1) to ensure that the mating halves and the electrical connections are securely joined, despite simple construction, whereby the invention may be used in as many different ways as possible.Type: GrantFiled: September 13, 2001Date of Patent: April 8, 2003Assignee: Tyco Electronics AMP GmbHInventors: Joachim Hahn, Carlo L'Abbate

Patent number: 5322448Abstract: An electrical connector assembly comprises a pin header connector and a socket connector for mating with the pin header connector. The pin header connector has a housing provided with a pair of opposed racks, the socket connector being provided with a pair of opposed levers each having a pinion. The levers can be swung by means of ganged handles to drive the socket connector into, and out of, mated relationship with the pin header connector. In the interest of simplifying the moulding of the pin header connector housing and of reducing its width, each rack projects above the upper edge of the pin header connector housing in substantially coplanar relationship with the respective side wall of that housing, the teeth of each rack overhanging the respective side wall.Type: GrantFiled: February 1, 1993Date of Patent: June 21, 1994Assignee: The Whitaker CorporationInventor: Joachim A.
