Abstract: A magnetic actuator (1 ) comprising a stationary part (3), a movable part (4) and a coil (10) arranged circumferentially relatively to the movable part (4) in such a manner that the movable part (4) is moved relatively to the stationary part (3) in response to a magnetic field induced when an electrical current runs in the coil (10). The stationary part (3) and the movable part (4) are shaped in such a manner that one is provided with a protruding part (5) and the other is provided with a recess (6) adapted to receive the protruding part (5). Thereby the minimum distance between the stationary part (3) and the movable part (4) are kept relatively low, and it is thereby possible to obtain a large pulling force without increasing manufacturing costs. The actuator (1 ) further comprises a shading ring (7) providing a magnetic field having a phase which is different from the phase of the field induced by the coil (10). This prevents the movable part (4) from repeatedly hitting the stationary part (3) and makes the actuator (1 ) suitable for use in AC as well as DC applications. The actuator (1 ) is suitable for use in a magnetic valve (9).

Abstract: The invention relates to an actuator for a valve in a refrigeration system. The invention also relates to a valve with such actuator, and to a refrigeration system with such valve. The actuator comprises an elongated Shape Memory Alloy (SMA) element extending along two or more string-like extensions from a distant end to a proximate end in relation to a valve element of a valve. The SMA element, when forming part of the valve, may extend from the distant end to the proximate end connected to a housing of the SMA element, however, electrically insulated from the housing. An encapsulation may provide a thermal resistance, a thermal conductor and/or an electrical resistance between the SMA element and other elements or the surroundings of the SMA element.

Abstract: An electromagnetic actuator, especially for the closure member of a valve, contains a solenoid unit (1), which has a cylindrical cavity (5) closed at one end and open at the other end. An axially introduced guide tube (2) for a magnetically movable armature (3) is arrestable in the cavity (5) by means of a securing device (19) engageable in a first recess (7) under spring force. To simplify connection of the actuator with and separation of the actuator from the component to be adjusted, provision is made for the securing device (19) to lie completely within the solenoid unit (1) and to snap automatically into the first recess (7) when the guide tube (2) is moved into a desired position in the cavity (5) of the solenoid unit (1).

Abstract: The invention relates to an ejector arrangement (1, 40) comprising a housing (11) and at least two ejectors (2, 3, 41, 42) arranged in said housing (11) along a common axis (13). Each ejector (2, 3, 41, 42) has a motive inlet (4, 5), a suction inlet (6, 7), an outlet (8, 9) and a valve element (23, 24, 43, 44). The task of the invention is to provide an ejector arrangement that allows for a good control of the mass flow of fluid through the ejector arrangement while keeping the construction simple. According to the invention the above task is solved in that the ejector arrangement (1, 40) comprises a common actuator (25, 55), that is arranged to engage at least two of the valve elements (23, 24, 43, 44) to open the motive inlets (4, 5).
