Abstract: An apparatus is for controlling a fluid flow. The apparatus has a valve provided with a valve adjuster for controlling a fluid flow through the valve. The valve has a fluid inlet in fluid communication with a fluid inlet conduit, and a fluid outlet in fluid communication with a fluid outlet conduit, for flowing fluid through the valve. The apparatus further has an actuator device capable of undergoing a change in shape, the change in shape of the actuator device providing via a connecting member an attenuated or amplified displacement of a fixation point connected to the valve adjuster, when compared to the change in shape of the actuator device.

Abstract: A protective device for a boat and a method of providing such a protective device which floats on a body of water are described, the protective device including a bottom portion which is arranged to be placed floatingly on or submergedly in the water underneath the hull of the boat, a top portion which is connected to the bottom portion, the top portion being constituted by a cloth-like material and being included at least as part of or being connected to a supporting device to be able to support at least a portion of the top portion in a distended position.

Abstract: A protective device for a boat which is floating in a water or is placed on land and a method of using same are described, the protective device including a top portion which is formed by a cloth-like material and which is bounded by a border area, the border area being arranged to be brought into substantially sealing contact with an adjacent portion in order thereby to provide a space defined by the adjacent portion and the top portion, and the top portion being included at least as part of or being connected to a supporting device to be able to carry at least a portion of the top portion in a distended position, the supporting device being activatable by means of a gas.

Abstract: The present invention relates to a regulating device (1) for regulating a fluid flow, the regulating device (1) comprising an actuator element (3) which is provided with a flow area (4) arranged to convey fluid between a fluid inlet (9) and a fluid outlet (13) and which includes a first restriction device (17), and a regulating device body (5) which is disposed at least in a portion of the flow area (4) and which is provided with a second restriction device (19) forming, together with said first restriction device (17), the restriction unit or choke device (17, 19) of the regulating device (1), the actuator element (3) and regulating device body (5) being arranged to move freely independently of each other as a consequence of a material expansion or material contraction, the throughput of the choke device (17, 19) being influenced by an energy source (21) which is arranged to supply energy to at least one of the actuator element (3) and/or regulating device body (5).
