Definitions

  • the invention relates to a rotary fluid regulator, in particular a rotary fluid regulator for controlling a fluid flow in a motor vehicle.
  • Rotary fluid regulators are known in the prior art.
  • DE 10 2011 120 798 A1 discloses a rotary fluid regulator with a housing and a rotary disk with openings is received rotatably in the housing. Fluid flow is led through the openings perpendicular to the plane of the rotary disk so that a diversion of the fluid through 180° is performed within the housing with an adverse effect on the pressure drop.
  • DE 100 53 850 A1 discloses a rotary fluid regulator in the form of an eccentric valve with at least one pivotable plate that can be placed in contact with a valve seat.
  • the disk pivots from the valve seat to control a fluid flow through an outlet opening.
  • the pressure drop is still very considerable due to the position of the disk during the opening of the valve.
  • the invention relates to a rotary fluid regulator having a housing with at least one inlet opening, at least one outlet opening, and a valve element that is received rotatably in the housing.
  • the valve element is of hollow form and forms a fluid duct.
  • a drive element is provided for rotating the valve element. Rotation of the hollow valve element can adjust or block a fluidic connection between the at least one inlet opening and the at least one outlet opening.
  • a brake element is provided for influencing or blocking the movement of the valve element. In this way, the position or setting of the valve element is controlled by interaction between the control of the drive element and the control of the brake element.
  • Two or more outlet openings may be provided so that a fluid flow can be distributed to one and/or the other outlet opening.
  • a fluid flow to be split up by the rotary fluid regulator in controlled fashion in accordance with the setting thereof.
  • Two or more inlet openings may be provided so that a fluid flow can be fed to one and/or the other outlet opening.
  • the rotary fluid regulator is also capable of mixing different fluid flows at the inlet side, for example in order to attain a targeted temperature of the mixed fluids.
  • the drive element may be an electromotive drive element, such as an electric motor, and may have an output element connected by a mechanism to the valve element to rotate the drive element.
  • the electric motor can be actuated in an effective manner and can act on the control element directly or via a mechanism.
  • the mechanism may be a speed-reduction mechanism that reduces the rotational speed of the electric motor, such that the valve element is rotated at a reduced rotational speed.
  • the drive element may be a hydraulic or pneumatic drive element, such as a hydraulic cylinder or vacuum capsule that has an output element connected by a mechanism to the valve element to rotate the valve element. In this way, too, a rotation of the valve element can be realized in a simple manner.
  • the mechanism may be a toothed-rack mechanism, a lever mechanism or a toothed-wheel mechanism. In this way, proceeding from the drive element, it is possible for the valve element to be driven in uncomplicated fashion so that the drive movement of the drive element is converted correspondingly into the movement of the valve element.
  • the brake element may be a magnetorheological brake element that can be actuated electronically so that a magnetic field can be applied in an electronically controllable fashion to achieve the braking action of the braking element.
  • the magnetorheological brake element may have an element that is received in displaceable fashion in a chamber.
  • the chamber receives a magnetorheological material that, in a magnetized state, inhibits the displacement of the displaceable element in the chamber and, in the non-magnetized state, substantially does not inhibit the displacement of the displaceable element.
  • the magnetized state is a state in which an externally applied magnetic field causes elements of the magnetorheological material to be interlinked and to exhibit an increased viscosity.
  • the displaceable element may be piston or slide that is longitudinally displaceable in the chamber. In this way, it is possible to utilize a targeted change in the viscosity of the magnetorheological material to influence the valve element.
  • the displaceable element may be a rotary piston or rotary slide that is received in rotationally displaceable fashion in the chamber.
  • a force store element such as a spring, may act on the drive element, on the mechanism or on the valve element so that, in the non-driven state, a force acts in the direction of a predefined position of the valve element so that the valve element is moved into the end position.
  • a force acts in the direction of a predefined position of the valve element so that the valve element is moved into the end position.
  • the valve element is moved into a predefined position to realize a defined functionality.
  • Such a position may be a defined end position.

  • the at least two elements 404 , 405 may be connected to one another in sealing-off fashion, for example, by welding or adhesive bonding or the like.
  • a seal may also be arranged in between.
  • the plunger 403 is in an elongate rod with a first end 406 in the housing 402 and a second end 407 led out of the housing 402 .
  • a movable element may be articulated to the second end 407 of the plunger 403 and can be actuated by the drive element 401 .

  • a diaphragm 409 is arranged in the housing 402 and is connected to the plunger 403 , for example, by a plate.
  • the diaphragm 409 and the housing 402 form a gas-tight pressure chamber 410 .
  • a pressure medium port 411 is provided on the housing 402 and enables the pressure chamber 410 to be charged with pressure or negative pressure by way of an external pressure medium supply or negative-pressure supply.
  • a spring may be arranged in the housing 402 , though this is not shown.
  • the spring may be supported between the housing 402 and the diaphragm 409 or the plunger 403 and may exert a force on the plunger so that a preload of the spring biases the plunger to assume a predefined position in the unpressurized state.
  • a sensor also may be provided on the housing 402 to detect the position of the plunger 403 .
  • a brake element 414 is provided and exerts a braking force on the plunger 403 with a corresponding braking action.
  • the brake element 414 is a magnetorheological brake element and has a brake housing 415 with two opposite openings 416 , 417 through which the plunger 403 is guided.
  • the brake housing 415 is formed in two parts with two sub-housings 418 , 419 that are connected to one another.
  • One sub-housing 419 may be of pot-like form, and the other sub-housing 418 may be a cover or plug.
  • Seals 420 are arranged at each of the two openings 416 , 417 for guiding and sealing the plunger 403 .
  • the sub-housing 419 of the brake housing 415 is formed in one piece with the housing 402 , for example by injection molding.
  • the plunger 403 has a flange-like piston 421 within the brake housing 415 .
  • the flange of the piston 421 projects radially from the plunger 403 and is guided through the magnetorheological material 422 in the brake housing 415 .
  • An electromagnet 423 or a coil is arranged around the brake housing 415 and can generate a magnetic field in the region of the magnetorheological material 422 .
  • the flange of the piston 421 moves through the magnetorheological material 422 as the plunger 403 is moved in an axial or longitudinal direction.
  • the plunger 403 can be displaced without a great amount of friction and thus without a great amount of resistance when no magnetic field is applied, because the magnetorheological material 422 can flow past the piston-like element 421 .
  • the elements of the magnetorheological material 422 interlink and the material becomes stiff or more viscous if a magnetic field is applied. In this way, the movement of the plunger 403 of the piston 421 through the magnetorheological material 422 is inhibited or braked or even stopped depending on the magnetic field that is applied.
  • the magnetorheological material 422 may be a dry magnetorheological powder or may be a magnetorheological fluid. This may be based, for example, on an oil or some other fluid, in which magnetic or magnetizable elements are embedded. Both types of magnetorheological material 422 have the characteristics that the material 422 is flowable and has a low viscosity in the non-magnetized state, whereas the material has a higher viscosity in a magnetized state when a magnetic field is applied. The reason for this is for example that the elements of the magnetorheological material 422 interlink and thus increase the viscosity.
  • the brake housing 415 of FIG. 18 is arranged adjacent to the housing 402 as viewed in the longitudinal direction of the plunger 403 .
  • the flange of the piston 421 may have at least one recess through which the magnetorheological material 422 can flow so that the piston 421 can slide easily through the magnetorheological material 422 .
  • a gap may be provided between the flange of the piston 421 and the wall of the brake housing 415 , through which the magnetorheological material 422 can flow when the plunger 403 moves.
  • FIGS. 19 and 20 show a further embodiment of a drive element 501 that is similar to the drive element 401 .
  • the brake housing 515 is connected to the housing 502 not by injection molding but by a holding plate 550 .
  • the holding plate is connected to the housing 502 with both the brake housing 515 and the magnetic field-generating element 523 screwed to the holding plate 550 .
  • a first screw 551 is provided for the screw connection of the brake housing 515 to the holding plate 550
  • second screws 552 are provided for the screw connection of the magnetic field-generating element 523 to the holding plate 550 .
  • the drive element may be an electromotive drive element, such as an electric motor.
  • the drive element may have an output element that may in be connected by a mechanism to the valve element to rotate the valve element.
  • the drive element also may be a hydraulic or pneumatic drive element, such as a hydraulic cylinder or vacuum capsule.
  • the hydraulic or pneumatic drive element may have an output element connected by a mechanism to rotate the valve element.
  • the mechanism may be a lever arrangement, a toothed-rack mechanism or a toothed-wheel mechanism.
  • the brake element has, as magnetorheological brake element, a displaceable element that is displaced in the magnetorheological material.
  • the displaceable element may be a type of piston or slide that is longitudinally displaceable in the chamber of the brake element, as shown in FIGS. 18 to 20 .
  • the displaceable element prefferably be a type of rotary piston or rotary slide that is received in rotationally displaceably in the chamber.
  • a displaceable element of said type is provided in the brake element of FIGS. 1 to 16 .
  • a force store element such as a spring, can be provided to act on the mechanism, on the drive element and/or on the valve element to cause a force to act in the direction of a predefined position of the valve element. It is thus possible to realize a failsafe function.
