Abstract
A linear spring-loaded actuator ( ) for a valve ( ) comprises a housing ( ) and an actuating spindle ( ) slidably supported in the housing ( ). A cap ( ) is associated with the housing ( ). Spring means ( ), arranged in the housing ( ), bear on the cap ( ) and the actuating spindle ( ), so as to exert a spring force on the actuating spindle ( ). A thread ( ) on the housing ( ) cooperates with a thread ( ) on the cap ( ) for screwing the cap ( ) on the housing ( ) so as to preload the spring means ( ) in the housing ( ). At least one lock means ( ) is associated with one of the threads ( ) and is capable of deforming this thread ( ) so as to lock it in any position on the cooperating thread ( ).
