Abstract: An economizer system and method for saving heat and water, comprising a bathing facility for receiving hot water from a water heater through a pipeline; a first valve for controlling the flow of hot water received by the bathing facility; a second valve for allowing the flow of an initial volume of cold water existing in the pipeline between the water heater and the bathing facility 1 through a filling line; and a holding tank for collecting the initial volume of cold water flowing from the filling line before the hot water is delivered to the bathing facility.

Abstract: The present invention refers to a conventional spur gear transmission or magnetic gear transmission, with a cycloidal configuration. The magnetic gears include contact points such that the mobile gear rolls on the fixed gear. Alternatively, a balance wheel is incorporated, which generates a centrifugal force opposite to the one associated with the mobile gear, of equal magnitude and on the same plane as this latter one, thereby completely eliminating the unbalancing of the mechanism. The balance wheel is mounted on the high-speed shaft in a manner similar to the mobile gear, and has the freedom to displace itself radially through centrifugal effect in the opposite direction to the eccentric position of the center of the mobile gear until it presses against a fixed track over which it rolls, concentric with the fixed gear with an equal force, opposite and collinear with that produced by the mobile gear.
