Valve controller and actuator for controlling actuating element, particularly gas exchange valve of internal combustion engine, has electromagnet, which faces valve head, with its pole surfaces, downward in housing

摘要

The valve controller has electromagnet (6,10), which faces the valve head (13), with its pole surfaces, downward in the housing (2). The electromagnet of the sliding anchor (7) slides freely in the partial section of the valve shaft (20) and is limited on upper and lower end side by the sliding anchor seat (17) and a compression spring (18), which is drawn and fixed with a pre-regulated minimum valve stroke (8). The electromagnet moves the anchor (3) till the maximum valve stroke (4), which is connected with the valve shaft in force-fit or form-fit manner.
