Fluid-operated actuator assembly
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).
