Definitions

  • An electrically operated valve comprises a distributor having a slide operative to selectively place a fluid actuated device in communication with a source of pressurised fluid, or with a fluid outlet.
  • the slide is actuated by an electrodynamic motor in response to a control signal, whereby the fluid pressure in the device [56] References Cited is dependent on the signal.
  • an electrically operated valve for delivering a fluid pressure governed by a control signal
  • feed pipe means means defining an outlet
  • a distributor said distributor having slide means selectively placing the feed pipe means in communication with a source of fluid under pressure or with the outlet, means subjecting the slide means to an axial force dependent on pressure within an associated fluid-actuated device and an electrodynamicmotor, said motor having a winding through which flows a current governed by the control signal, the said winding constituting the moving part of the electrodynamic motor and being connected to the slide means
  • the force acting on the winding and the force dependent on the pressure in the associated device are opposite in direction so as to balance each other at least partially; the pressure in the associated device is then an increasing function of the control signal.
  • the force acting on the winding and the force dependent on the pressure in the associated device act in the same direction, the valve having means for applying to the slide means a forceopposite in direction to the foregoing two forces; the pressure in the associated device is in this case a decreasing function of the control signal.
  • This embodiment of the invention is particularly useful in preventing wheel lock on a motor vehicle, the electrically operated valve being interposed between the pressure source and a brake cylinder of a braked wheel, the control winding being energised by a signal having a mean intensity dependent on, for instance, the degree of wheel slip.
  • the valve has a chamber connected to the feed pipe, within which chamber a transmission or thrust member connected to the slide means and smaller in section than the latter is mounted with freedom to move.
  • FIG. 1 is a section of one embodiment of a valve in accordance with the invention.
  • FIG. 2 is a section, to an enlarged scale, of a portion of a valve
  • FIGS. 3 to 7 are sections showing details of other embodiments of the invention.
  • the pressure source consists of a hydraulic accumulator 11, charged from a tank 12 by a pump 13, and maintaining a pressure P higher than that which normally exists in a fluid actuated device 15.
  • An intermediate feed pipe passage 14 is connected to the device 15, represented diagrammatically by a ram. According to the position of the slide 3, the passage 14 is either closed by the intermediate bearing portion 7 or partially or fully in communication with either the groove 4 or the groove 5.
  • One end of the bore 2 opens into a chamber 16 of the same section, and which is connected to the passage 14 by a passage 17.
  • the slide 3 is actuated by an electrodynamic motor; in other words the motor applies the force F to the slide 3.
  • the motor incorporates a permanent magnet 18 mounted between a pole piece 19 and the end wall of a pot-shaped magnetic yoke 20 so as to define, in conjunction with the pole piece 19, an annular gap 21; the yoke 20 is fixed to the body 1 of the distributor.
  • a winding 22 supported on a cup 23.
  • the cup 23 is biased against the end of the slide 3 by a spring 24; a spring 25 mounted within the chamber 16, acts in opposition to the spring 24 whereby, when a control signal is zero, the slide is located in an equilibrium position in which the axial surface of the bearing portion 7 which faces towards the groove 5 lies in the transverse plane of that position of the generator line of the passage 14 which is nearest to the groove 5 (as shown in FIG. 2).
  • the magnet 18 is replaced by a ring magnet 18, fitted around an H- .sectioned member 34, in which the limbs of the member 34 are of unequal length, an annular air gap 21 being defined between the shorter limb of the member 34 and a ring 35.
  • the magnet 18 is replaced by a coil 36.
  • a current which varies with the signal can be passed through the coil 36 and/or the winding 22.
  • the winding 22 is fixed on a drum 26 slidable to an axial hub 27, fixed to the pole piece 19.
  • the drum 26 is connected by two or more levers 28, pivotally mounted at 29 on the body 1, to a cup 30, biased against the slide 3 by a spring 24.
  • the pivot 29 is nearer to the pivotal connection between the levers 28 and the cup 20 than to the pivotal connection between the levers 28 and the drum 26.
  • FIG. 6 The embodiment of FIG. 6 is generally similar to that shown in FIG. 1 except that the cup 23 is hooked over the slide 3. Additionally, a thrust pin 31 extends axially through the pole piece 19, the cup and the magnet 18, which is ring-shaped for this purpose, and bears against the slide 3.
  • the pressure P in the device 15 is proportional to a force (I) exerted on the pin 31; when current of mean strength l,, is passed through the winding 22 in a sense to move the winding 22 to the left as viewed in FIG. 6, it exerts on the slide 3 a force F proportional to 1,, and opposite in direction to the forcef.
  • the pressure P, falls and becomes proportional to f F, that is to say that the value by which it falls is proportional to l,,,.
  • the bore 2 is connected to a chamber 16 by an aperture through which a thrust pin 32 extends. Equilibrium is established when the value of the force F is equal to s.P,,, s being the cross-sectional area of the pin 33. The force F is thus smaller than the value it will have in the embodiment in FIG. 1.
  • the spring 24 can be pre-stressed as to bring the slide 3 into a position in which the passages 9 and 14 are in communication even at maximum pressure. Then, the winding 22 being arranged to be energized so as to be subjected to a force directed towards the left as viewed in FIG. 1, the pressure in the device 15 would have a value P in the absence of current in the winding 22, but, with current flowing through that winding, would fall by an amount related linearly to the mean strength of that current.
  • said distributor having slide means selectively placing the feed pipe means in communication with said source of fluid under pressure and with the outlet,
  • g. means subjecting the slide means to a first axial force dependent on pressure within said associated fluid-actuated device
  • an electrodynamic motor having a winding through which flows a current governed by the control signal, the said winding constituting the moving part of the electrodynamic motor and being connected to the slide means to apply a second axial force thereto.
  • a valve as claimed in claim 4 further comprising linking means connecting the winding to the slide means, said linking means applying a mechanical advantage to the slide means.
  • valve as claimed in claim 1, in which the force acting on the winding and the force dependent on the pressure in said associated device act in the same direction, said valve further comprising means exerting a force on the slide means opposite in direction to the other forces.
  • a valve as claimed in claim 6, in which the means exerting the opposite force comprises a spring.
  • a valve as claimed in claim 1, in which the said means subjecting the slide means to a force dependent on the pressure in the associated device comprises means defining a chamber in communication with the feed pipe means, and
  • the thrust member being smaller in section that the slide means, one end portion of the thrust member being received in said chamber, and the other end of the thrust member being movable with the slide means.
