Abstract:
1. A valve comprising: a housing including an inlet opening for a fluid and an outlet opening for the fluid; a closure element through which a flow of the fluid is controllable; an actuation device including an electric actuator for adjusting the closure element; a drive housing at which a stator of the electric actuator is fixated, wherein the fluid is at an inlet pressure at the inlet opening and at an outlet pressure at the outlet opening, wherein a moving element of the electric actuator is kinematically coupled with the closure element in an inner cavity of the drive housing, wherein the inner cavity of the drive housing is filled with a liquid, wherein the inner cavity of the drive housing is pressurized with a pressure from the fluid, wherein the stator is disposed in the inner cavity of the drive housing, wherein the inner cavity of the drive housing is separated from the fluid through a moveable divider element that is not kinematically coupled with the closure element, and wherein the divider element is hydraulically moved by a distance greater than zero by an amount of the liquid when the amount is displaced from the inner cavity of the drive housing through an actuation of the actuation device when adjusting the closure element.
