    摘要： A hydraulic actuator for a hydraulic servomotor (4) is disclosed. The hydraulic servomotor (4) is of a kind having at least one defined end position, and has a first chamber (5) and a second chamber (6) associated therewith. The actuator is connected to a fluid source (2) and a fluid drain (3). The actuator comprises a first valve (7) fluidly connected between the fluid source (2) and the first chamber (5), a second valve (8) fluidly connected between the first chamber (5) and the fluid drain (3), and a third valve (9) fluidly connected between the fluid source (2) and the second chamber (6). The actuator further comprises a flow channel (10, 17), preferably comprising a flow restrictor (12, 18), in fluid communication with the second chamber (6).The valves (7, 8, 9) are such that, in the case of a power cut off, they will prevent a fluid flow out of the first chamber (5), and a fluid flow out of the second chamber (6) takes place via the flow channel (10, 17). This will cause a servomotor piston member (13) to move towards the second chamber (6), thereby moving the hydraulic servomotor (4) to an end position.

    摘要： The present invention concerns an electrode for establishing electrical contact with the skin. The electrode comprises an electrically conductive gel (12) covering a part of a first side of an electrically conductive layer (4) and an electrically conductive by-pass element (19). The by-pass element extends, on the second side of the electrically conductive layer, over the circumference of the gel on the first side and is in electrical contact with the second side of the electrically conductive layer at a point opposing an area covered with electrically conductive gel at the first side of the electrically conductive layer. The by-pass element ensures that the electrode continues to be operable even if exposed to chemical or mechanical stress.

    摘要： The invention concerns a valve arrangement for controlling a hydraulic drive having a first working connection (A) and a second working connection (B), and being connectable with or separable from a pressure source (P), the supply and the outflow of the hydraulic drive being separately controllable. It is endeavoured to improve the energetic efficiency of the valve arrangement. For this purpose, the first working connection (A) is connected with a first control valve and the second working connection (B) is connected with a second control valve, the first and the second control valves being connected with each other and with a third control valve, which is connected with a tank.

    摘要： A hydraulic actuator for a hydraulic servomotor 4 is disclosed. The hydraulic servomotor 4 has a first chamber 5 and a second chamber 6 associated therewith. The hydraulic actuator is connected to a fluid source 2 and a fluid drain 3, and it comprises a valve assembly arranged between the fluid source 2 and the fluid drain 3 to control fluid pressures in the chambers 5, 6. At least one auxiliary valve 11 is fluidly connected between the valve assembly and the fluid drain 3, said auxiliary valve(s) 11 being of a kind which is normally closed in a de-energized state. In the case of a power cut off the auxiliary valve(s) 11 will close, thereby preventing fluid flow from the valve assembly towards the fluid drain 3. This causes a servomotor piston member 12 to be hydraulically locked in its instantaneous position, thereby locking the hydraulic servomotor 4. The valve assembly may be designed without taking the locking function into consideration.

    摘要： A wound dressing comprising a backing layer and an absorbent layer, wherein the absorbent layer comprises a wound facing surface and a non-wound facing surface, said absorbent layer comprises discrete foam pads covering at least 50% of the wound facing surface of the absorbent layer and wherein the non-wound facing surface of the foam pads are attached to the backing layer. The structure of the dressing renders it possible for the foam to expand during wetting without changing the external dimensions of the absorbent layer substantially.
