    摘要： A fluid-operated actuator assembly (10) has a valve (100) with an inlet (110) for connection to a pressurized fluid source (1), a bi-stable electromagnetic device (200) for operating the valve (100), which has a first state closing the valve (100) and a second state opening the same, a hydraulic actuator (300) and an electronic control circuit (400). The hydraulic actuator (300) has an actuating member (310) in a housing (320). The housing (320) has a chamber (321) on one side of the actuating member (310) to which an outlet (120) of the valve (100) is connected for receiving fluid from the fluid source (1) when the valve (100) is opened in order to act upon and move the actuating member (310) for operation of the hydraulic actuator (300). The control circuit (400) momentarily energizes the electromagnetic device (200) to change it from the first state to the second state to enable operation of the hydraulic actuator (300) and subsequently from the second state back to the first state to terminate operation of the hydraulic actuator (300). The invention also provides a toilet cistern (20) including the fluid-operated actuator assembly (10), and a toilet (30) including the toilet cistern (20).

    摘要： To perform boom-down operation by operating a boom cylinder (6) by an external load (W) while simultaneously operating an arm cylinder (26) or a bucket cylinder (27) in the state the bucket is off the ground, a first boom directional control valve (2) and a regeneration boom valve (13) are controlled to the neutral position and the open position respectively so that the hydraulic oil is regenerated from a line (9) located at the oil-returning side of the boom cylinder (6) through the regeneration boom valve (13) to a line (5) located at the oil-feeding side. Therefore, the volume of the hydraulic oil that can be supplied from the pressurized oil source (4) to the arm cylinder (26) or the bucket cylinder (27) via the second arm directional control valve (24) or the bucket directional control valve (25) is increased by the amount equivalent to the amount of the oil that is not supplied from the pressurized oil source (4) to the boom cylinder (6). As the circuit according to the invention enables the arm cylinder (26) or the bucket cylinder (27) to work faster, it increases the operating efficiency of the hydraulic excavator when its hydraulic actuators are operated simultaneously.

    摘要： The aim of the invention is to adjust the force generated by a first piston (12) in accordance with its stroke. Said first piston (12) is displaced in a first cylinder (10) which by the first piston (12) is divided into a first and a second chamber (16, 18). A fluid under pressure (32) is fed into the first chamber (16). The invention provides for a second cylinder (20) in which a second piston (22) is displaced and which by said second piston (22) is also divided into a first and a second chamber (26, 28). The two pistons (12, 22) are mechanically coupled (30) so that the second piston (22) is driven by the first piston (12). The second chamber (18) of the first cylinder (10) is connected via a line (42) with the first chamber (26) of the second cylinder (20) so that the same pressure prevails in both chambers (18, 26). The pressure in the second chamber (28) of the second cylinder (20) is appropriately adjusted in such a way that it is always equal to the back pressure in the first chamber (26) of the second cylinder (20) and the second chamber (18) of the first cylinder (10). The initial value of the back pressure in the second chamber (18) of the first cylinder (10) can be adjusted. If the diameter of the second cylinder (20) is greater (smaller) than that of the first cylinder (10), the back pressure falls (rises) when the first piston (12) is displaced outward and the force produced by the first piston (12) rises (falls) linearly according to the piston stroke.
