Disclosed is an actuating device (16) for a pump unit which is provided for use in a can (10) of a pump unit for application of force to a shaft (6) located in the can (10), comprising a support (32, 34, 36) which is designed for connection to the can (10) and has a passage extending along a longitudinal axis (X), having an actuating pin (38) which is guided in this passage along the longitudinal axis (X) and has a tool holder (44) on the first axial end (42) of the actuating pin and an engagement area (48) for transmission of force to a shaft (6) on the opposing second axial end (46) of the actuating pin, and having a spring element (58) which is disposed between the actuating pin (38) and the support (32, 34, 36) and which exerts a spring force on the actuating pin (38) in the direction of the first axial end (42) thereof, wherein a seal (52, 52') is disposed between the support (32, 34, 36) and the actuating pin (38) in a region between the spring element (58) and the second axial end (46) of the actuating pin (38). The invention further relates to a pump unit having such an actuating device (16). |
