Abstract: A linear actuator (1) comprising a first part (3) and a second part (5) is disclosed. The first part (3) is arranged to rotate along with a rotating part (4) of a motor (2), and the second part (5) is arranged to drive an actuated part (18, 22). A coupling (6) interconnects the first part (3) and the second part (5) to allow the second part (5) to rotate along with the first part (3) at the same angular velocity as the first part (3). The coupling (6) defines a fit tolerance between the first part (3) and the second part (5) allowing the first part (3) to rotate a predefined distance before engaging the second part (5) and rotating the second part (5) along with the first part (3). The fit tolerance ensures that the first part (3) reaches a certain angular velocity and thereby that the resulting torque transfer from the first part (3) to the second part (5) is sufficient, e.g. to release the actuated part (18, 22) from a pretensioned state.

Abstract: The present invention relates to a top cover (5) for soft throttling valve body (2), the top cover (5) comprising one or more fluid conduits for transferring a pilot fluid flow for setting a degree of opening of a main valve situated in a soft throttling valve body to the soft throttling valve body. Furthermore, the invention relates to a soft throttling valve (1) and a method for assembling the soft throttling valve (1).
The object of the invention is to allow a good control of the pilot fluid flow while protecting the soft throttling valve body from damage due to valve failure.
The object is solved by having a follower arrangement arranged to throttle the pilot fluid flow depending on the degree of opening of the main valve, further having a manual opening arrangement for manually opening the main valve and/or by further preventing a step-wise opening of the main valve in less than two opening steps.
A method for assembling a soft throttling valve is also disclosed.

Abstract: The present invention relates to a top cover (3) for a soft throttling valve body (2), to a soft throttling valve (1), and to a method for throttling a main valve of a soft throttling valve (1). A follower arrangement (8) is arranged to throttle a pilot fluid flow for setting a degree of opening of the main valve in order to allow a soft throttling of the main valve, a throttling of the pilot fluid flow depending on a degree of opening of the main valve, so as to allow for a soft throttling process of the main valve. Thus, a self-controlled throttling of pilot fluid flow driving the main valve in order to establish a partial opening of the main valve becomes possible. By that, a good prevention of pressure shocks when throttling the valve is allowed and a good control for partially opening the main valve is achieved.
