Pneumatic or hydraulic actuator e.g. for actuator, has housing having pneumatically, or hydraulically movable mechanical drift element relative to housing and drift element moves to quiescent position linking up with spring element

摘要

The actuator (2) has a housing (4) having pneumatically, or hydraulically movable mechanical drift element (10, 12) relative to the housing. The drift element moves to a quiescent position linking up with a spring element (18). A spring action (32) of the spring element pushes against a load cell (22). The load cell is arranged between spring element (18) and housing (4) or drift element and arranged for transferring the load.
