Abstract
A valve actuation mechanism for actuating a rotatable closing valve element for cryogenic applications and/or H2 applications, including a housing defining an inner area sealed by a membrane from an outer area, an input shaft configured to receive a rotational movement, the input shaft being in the outer area, an output shaft configured to be connected to the closing element, wherein the output shaft is in the inner area, and a strain wave gearing connecting the input and output shafts. The strain wave gearing includes a wave generator connected to one of the input and output shafts, a rotatable outer gear wheel connected to the other one of the input and output shafts and a stationary flexible ring gear with external teeth deformed by the wave generator to engage with internal gear teeth of the outer gear wheel. The flexible ring gear is a portion of the sealing membrane.
