Patent number: 10912285Abstract: In a support device for aquarium accessories including a first fixing element appliable on the inner surface of a wall of an aquarium and a sustaining element for an accessory supportable by the first fixing element, the first fixing element has a concave cap and the sustaining element has a convex cap housable at least partially inside the concave cap. Furthermore, the support device includes a cap-shaped first magnetic or ferromagnetic element, the first fixing element includes a second magnetic or ferromagnetic element, and the convex cap of the sustaining element is interposed between the concave cap of the first fixing element and the first magnetic or ferromagnetic element so that, due to magnetic attraction between the first magnetic or ferromagnetic element and the second magnetic or ferromagnetic element, the sustaining element is supported by the first fixing element and, at the same time, it is rotationally movable.Type: GrantFiled: July 6, 2015Date of Patent: February 9, 2021Assignee: HYDOR SRLInventor: Valerio Bresolin

Patent number: 10174761Abstract: A synchronous electric motor for operating a pump includes a motor body, a stator and a rotor coupled to an impeller of the pump. The motor also comprises a cylindrical element that extends towards the inside of the motor body from one of its outer walls so as to define a first cylindrical cavity open to the outside to insert inside the rotor, wherein the rotor has a circular cross section essentially corresponding to the inner section of the cylindrical element so that the rotor is in contact with the cylindrical element and then there is a friction between the rotor and the cylindrical element when the rotor rotates, and the rotor is shaftless and axially and directly coupled to the impeller of the pump.Type: GrantFiled: May 22, 2017Date of Patent: January 8, 2019Assignee: HYDOR SRLInventor: Valerio Bresolin

Patent number: 8191846Abstract: A magnetic support (10) for aquariums includes a first and a second support element (20a, 20b), each of them having a magnet (26a, 26b) so that by coupling the first and second support elements (20a, 20b) by interposing an aquarium wall (50) between them, the attracting magnetic force operating between the two magnets (26a, 26b) locks the two support elements (20a, 20b). Each support element (20a, 20b) comprises a flat element (40a, 40b) made up of flexible material having a peripheral projecting lip (46a, 46b), so that when the two support elements (20a, 20b) are coupled together by interposing the wall (50), the peripheral projecting lips (46a, 46b) are flattened against the wall (50), thus creating a suction effect.Type: GrantFiled: June 14, 2007Date of Patent: June 5, 2012Assignee: Hydor SRLInventor: Valerio Bresolin
