    • An actuator arrangement for moving first and second members (3, 4), the two members (3, 4) being interconnected with one another by a linkage (5) extending between them. The arrangement comprises first and second actuator means (6, 7) arranged to bear against respective movable members (3, 4) such that actuation of the first actuator (6) causes both movable members (3, 4) to move in one direction and actuation of the other actuator (7) causes both movable members (3, 4) to move in the opposite direction. A locking mechanism (20, 21) is coupled with the first and second actuators (6, 7) and is so arranged as to allow free movement in opposite directions caused by actuation of the first and second actuator means respectively but to prevent movement in either direction when not caused by actuation of the respective actuator means.
    • 一种用于移动第一和第二构件(3,4)的致动器装置,两个构件(3,4)通过在它们之间延伸的连杆(5)相互连接。 该装置包括第一和第二致动器装置(6,7),该第一和第二致动器装置布置成抵靠相应的可动构件(3,4),使得第一致动器(6)的致动引起两个可动构件(3,4)沿一个方向移动并且 另一个致动器(7)的致动导致两个可移动构件(3,4)沿相反的方向移动。 锁定机构(20,21)与第一致动器和第二致动器(6,7)联接并且布置成允许分别由第一致动器装置和第二致动器装置的致动引起的沿相反方向的自由移动,但是防止移动 当不是由相应的致动器装置的致动引起时。

    • The present invention provides an alarm for a hydraulic system, a hydraulic system incorporating an alarm, a vehicle having a hydraulic system which incorporates an alarm, and a method of giving an alarm in a hydraulic system.
      The hydraulic system comprises hydraulic fluid which is put in contact with a pressure detector, the pressure detector being for giving a signal in response to a condition of the hydraulic fluid in the hydraulic system. An alarm generator integral with said pressure detector is provided for giving an audible alarm in response to said signal.
