  • Patent number: 10981804
    Abstract: A hydraulic control and/or safety device, particularly for utility apparatuses or systems or appliances, which is preferably able to carry out a flow shut-off and/or limitation, particularly in the event of fault of the utility apparatus or system or appliance, and/or one or more features that improve the device and/or the apparatus performance. In particular, the device can carry out the function of the fluid treatment, so as to be particularly reliable, as it prevents at least the formation of deposits on its mechanical components designed to limit the water flow.

  • Patent number: 10132300
    Abstract: A device is described wherein a pair of thermal or electrothermal actuators (3, 4; 103, 104) actuate a member, such as a pinion (5), between two stable positions. The actuators are alternately activated for moving the pinion between the stable positions. For this purpose, they are arranged close to each other, so that they can act upon the pinion on opposite sides, the pinion being held in the stable positions by a releasable engagement element. The device of the invention ensures low energy consumption because the actuators (3, 4) operate only for moving the pinion from one stable position to the other.

  • Patent number: 9786455
    Abstract: A device is described wherein an actuator (3, 4; 103, 104) drives a member, such as a rack (6) meshed with a pinion (5), between two stable positions. For this purpose, elements for stopping the movable member are provided, which cooperate with elements present on the outer housing (2, 21), in which the actuator and the movable member (5, 51) are arranged, for holding at least one of said stable conditions. The device of the invention ensures low energy consumption because the actuator (3) only operates for moving the movable member from one stable position to the other.

  • Patent number: 9127482
    Abstract: The invention relates to a door lock device for household appliances such as washing machines, clothes dryers and the like. The device comprises a slide (6) which is movable between a door lock position and a door unlock position, and which cooperates with a coupling tooth arranged on the door in order to hold the door locked when the household appliance is in operation. The device is fitted with a thermoactuator (4) that drives the slide (6) by imparting thereto a translational motion between a door lock position and a door unlock position.

  • Patent number: 8752376
    Abstract: An electro-thermal actuator device includes a case defining a cavity in which are housed a thermal actuator, an electrical heater and, at least partially, an actuating shaft. The device comprises a multipolar connector for the rapid, secure and reliable coupling to a respective source of electrical power supply for the heater. The connector can be configured as an adapter unit distinct from the case, suitable to transform a traditional electro-thermal actuator device into the actuator device described above.

  • Patent number: 8651336
    Abstract: A long-life substance dispensing device for a washing machine, particularly a dishwasher, comprises: —a body (20?, 30?) designed to be sealingly fixed to a structure of the washing machine, —a support means (40) adapted to contain a total amount of a substance sufficient for performing a plurality of washing cycles, —an actuation system (47?, 50?, 61?) which is electrically controllable for causing delivery of at least one dose of the substance contained in the support means (40). The actuation system (47?, 50?, 61?) comprises at least one drive element and one driven element (47?) capable of cooperating to obtain the delivery. The actuation system (47?, 50?, 61?) is arranged for being able to take on an operative condition, wherein the drive element (61?) is operatively coupled with the driven element (47?), and an inoperative condition, wherein the drive element (61?) is decoupled from the driven element (47?).

  • Publication number: 20110087367
    Abstract: A support (40) contains a plurality of separate doses (46) of deliverable substances. The support is arranged to be operatively coupled to a long-life dispensing device. The support is intended to be either coupled to or inserted within the dispensing device, such that a relative movement of the support and at least one part of the dispenser body that is caused by an actuating system allows selectively delivering at least one substance dose. The support integrates reference means (49a), (49b) that are configured to provide, due to said relative movement, information on at least one of: doses of the substance provided within the support, a condition and/or a position of the support within the dispenser.
