Patent number: 10981804Abstract: 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.Type: GrantFiled: August 25, 2016Date of Patent: April 20, 2021Assignee: ELTEK S.P.A.Inventors: Renato Gaj, Luciano Bianchi, Fiorenzo Pivetta, Costanzo Gadini

Patent number: 10132300Abstract: 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.Type: GrantFiled: March 25, 2014Date of Patent: November 20, 2018Assignee: ELTEK S.P.A.Inventor: Renato Gaj

Patent number: 9786455Abstract: 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.Type: GrantFiled: March 25, 2014Date of Patent: October 10, 2017Assignee: ELTEK S.P.A.Inventors: Renato Gaj, Costanzo Gadini

Patent number: 8651336Abstract: 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?).Type: GrantFiled: August 8, 2008Date of Patent: February 18, 2014Assignee: Eltek S.p.A.Inventors: Costanzo Gadini, Renato Gaj, Marco Moro, Chris Efstathios Housmekerides
