Definitions

  • the present patent is for a Utility Model of a System for Activating the Rotor of a Water Flow Valve used in the automotive industry, and installed between the connection between the engine with the radiator and the system for heating the vehicle cab, its main function being to divert hot water from the engine to the heating system installed in the vehicle cab.
  • the rotor is activated manually by means of an external handle attached to a square shaped extension projecting from the top of the rotor and exposed outside the housing.
  • the improvement here proposed is based on the fact that the activation of the rotor happens by motorized mechanical means, by eliminating the manual lever and introducing a transmission device, activated by a micro-motor attached to the valve housing.
  • FIGURE 1 Shows the components of the system for activating the rotor of the water flow valve, separately.
  • FIGURE 2 Shows a schematic view of the system for activating the rotor, giving the position in which it is attached to the water flow valve.
  • FIGURE 3 Shows the front view of the water flow valve with the rotor activating system attached.
  • FIGURE 4 Shows the view from above of the water flow valve with the rotor activating system attached.
  • the water flow valve is not a characterization element of this patent application and is only shown in the attached drawings and mentioned in the description as an example for showing how the rotor activating system is used and assembled.
  • the aforementioned water flow valve is characterized by a housing containing a compartment which holds the rotor and by having an adjacent cavity, linked by an intermediary channel for diverting liquid (a bypass) or returning it to the engine when it is not being directed towards the heating system.
  • An inlet tube for hot water coming from the engine and an outlet linking it to the vehicle cab heating system is attached to the rotor activating compartment.
  • An outlet tube for the liquid returning from the engine cooling system (radiator), and an inlet for liquid returning from the cab heating system, are linked to the adjacent cavity.
  • the rotor has an attachment system which allows a sealing device to be joined to it and this is responsible for the perfect sealing of the liquid, to prevent it from going towards the heating system when the cab does not need to be heated, and a seal to the bypass, when the cab needs heating.
  • the mechanical system in question comprises a modular crown (1) which has a central square- shaped orifice (2); an axle (3) which has a worm screw (4) on one end and a gear wheel, (5) on the other; a worm screw (6) which can be attached to the axle of the engine; and a micro-motor
  • the crown (1) is attached by means of the central orifice (2) in the square pin (11) projecting from the top of the water flow valve rotor and outside the housing.
  • a flat extension (8) was added to the flow valve housing (12) and on which two blocks have been mounted, duly separated and aligned (9) and (10), and these constitute the mountings for installing the axle (3), in such a way that the worm screw (4) meshes with the crown (1), and the gear wheel (5) meshes with the worm screw (6), which is attached to the axle of the micro-motor (7), which is also attached to the flat extension (8) and linked to the electrical system of the vehicle.
  • the water flow valve rotor can be activated by the user by means of the micro-motor that transmits movement to the axle (3), which, by means of the worm screw (4), moves the crown (1), which consequently moves the rotor in such a way as to allow it to fulfill its function.
