Abstract: A detection device for a liquid-conducting appliance includes a hydraulic body (2) defining a duct (3) for a flow of a liquid, and a flow sensor on the hydraulic body (2), which includes an electromagnetic arrangement and a detection arrangement. The detection arrangement includes two electrode units (20) for detecting a potential difference induced by the flow of the liquid through an electromagnetic field generated by the electromagnetic arrangement. The hydraulic body (2) has two through openings on two opposite sides (3a, 3b) of the duct (3), inserted in each of which is a corresponding electrode unit (20), in such a way that the electrode units (20) are opposed to one another and in contact with the liquid. The device (1) includes sealing elements at each through opening, for preventing leakage of the liquid from the duct (3).

Abstract: A dispenser of washing agents for washing machines has a first tank, to contain a first washing agent, and a first dispensing arrangement, to dispense first dosed amounts of the first washing agent. The first dispensing arrangement has a peristaltic pump, which is configured to be driven in a first direction of rotation to cause delivery of the first dosed amounts of the first washing agent. The dispenser has a second tank, to contain a second washing agent, and a second dispensing arrangement, to dispense second dosed amounts of the second washing agent. The peristaltic pump has a command arrangement of the second dispensing arrangement, and is configured to be driven in a second direction of rotation, to drive the command arrangement so as to cause dispensing of the second dosed amounts of the second washing agent.

Abstract: A hydraulic control device for liquid-conducting appliances and systems is designed for connection between a source of liquid and an appliance or system using the liquid. The hydraulic control device (1) comprises: —a device body (2′, 3′) having a duct for the liquid (30a, 30b) that extends between an inlet connector (2a) and an outlet connector (3 a); —a flow meter (40, 50) associated to the device body (2\ 3′); and—a valve arrangement (31, 33-37) associated to the device body (2′, 3′), including a valve member (31), which is displaceable between an opening position and a closing position of the duct for the liquid (30a, 30b), and a control mechanism (33-37) for controlling the valve member (31). The control mechanism (33-37) is switchable on the basis of a detection made by the flow meter (40, 50) in order to displace the valve member (31) from the opening position to the closing position of the duct for the liquid (30a, 30b). The flow meter (40, 50) is a non-mechanical flow meter that includes at least two electrical detection elements (42) that are reachable by liquid that flows in the duct for the liquid (30a, 30b).
