Definitions

  • the present invention relates to improvements in pressure compensating devices for multiple gas chambers and is a division of application led April 19, 1935, and in one i instance the invention relates more particularly to a device for eq-ualizing pressure between the air chambers of twin automobile tires.
  • Another object an improved c l maintain a const of the invention is to produce ompensating device which may ant pressure difference between two gas or air chambers where it is desirable that the pressure be not at predetermined
  • the invention equalized but be maintained pressure differences.
  • l has for a further object the i production of a compensating device for the purpose indicated which is made up of simple parts grouped in a simple organization.
  • the device ch may be used either alone or in any appropriate numbers or combinations.
  • Figure 1 is a diagrammatic view of a unitary compensating device constructed in accordance with the present Figure 2 is a. in Figure l.

  • the chambers 2 and 3 are provided with one or more ports 5 and 6 disposed on opposite sides of the partition 4 and these ports are arranged to communicate with the interior space housed about by a iiexible or elastic membrane sleeve I0 bound securely, as indicated at 'I and 8, to the metal orv other tube I at opposite sides of the ports 5 andi.
  • the device may be contained within a collar or casing 9 allowing ample room for the membrane I 0 to expand outwardly from the outer wall of the tube I.
  • the membrane III by reason of its own inherent elasticity, will seek a position stretched rather tightly over the outer cylindrical circumference of the tube I so as to close both ports 5 and 6 and in this respect it functions as a valve for both of the ports, acting independently and locally upon each port.
  • Figure 7 is a cross section showing a combination unit.
  • Figure 8 is a grouping of a plurality of the Figure 9 is a sectional view diagramma-tic view showing a units
  • yhamber 2 may pace of one aut becomes greater than that in the companion chamber, the gas ows from that chamber to the other chamber through the equalizing device un-A til stability of pressures is restored. 'Ihis will go on automatically maintaining a condition of equality of pressures of the two chambers 2 and 3. below the predetermined her will flow over to dist tain pressure equality.
  • the membrane sleeve I0 will first collapse against the port i of the chamber 3 in which the heavy fall in pressure has In other wordsl the device will shown in Figure 2 before lt returns to the position I.”
  • the distention of the membrane sleeve I0 in response to the pressure within either chamber will depend upon the tension inherent in the rubber sleeve lli and also upon the port area or diameter of the ports and 3. From the moment the membrane sleeve Iii closes to the position shown in Figure 2, communication is prevented between the two chambers 2 and 3 and the defiating chamber can continue to defiate without affecting the pressure condition of its companion chamber.
  • the two chambers will remain at equal pressures provided such pressures exceed a predetermined minimum which minimum depends upon the tension of the rubber sleeve I0 land the cross sections or port areas of the ports 3 and 3.
  • the intethe collar I and the membe open at the ends of the device 3 is located a desired disfree 'collar to the atmosphere so that there is no coniined air space interfering with the free movement of the membrane sleeve III.
  • FIG. 4 in which a modified form of device indicated generally at B is provided.
  • a similar arrangement of tube i, chambers 2 and 3, partition 4. ports 3 and 3 and membrane sleeve i0 is provided: but in this case instead of providing a"collar.
  • an enclosed casing 3* is fitted tightly to the tube i at the opposite ends of the membrane sleeve i0 and this casiin'gl 3l houses a connned volume of air about the membrane sleeve Iii.
  • the end walls 3 of the casing 3l are provided with out-turned flanges or bearing portions 0b which are fitted in an air-tight manner about the pipe or tube i.
  • the confined space within the casing 3l is placed in communication with one of the chambers, for instance the chamber 3, by an orifice or port l2.
  • the chamber 3 will always be at a lower pressure than chamber 2. Assume that pressure is being introduced into chamber 2; then acting through the port 5 and against the rubber membrane sleeve iii it will expand such sleeve away from the tube i in the manner already described in connection with Figures l, 2, and 3.
  • This elastic tension or contractile stress within the rubber sleeve i0 is augmented or supplemented by the external pressure in the enclosed casing 3* acting on the outside of the sleeve.
  • the device B shown in Figure 4 will have as its effect to maintain between chambers 2 and 3 a normal difference of pressure which will depend. all other things being equal. on the initial or inherent 'tension of the. sleeve l0. If the pressure becomes lower in the low pressure chamber 2' must the pressure in the high pressure chamber will drop by reason of the opening of the valve and the flow of gas from chamber 2 to chamber 3; and this action will continue until sufllcient pressure in chamber 3 is established to permit closing ol the valve I0, at which time there will be a substantial re-establishment of the pressure differential between the two chambers 2 and 3. Thus the pressure differential will be for all purposes a constant. Whenever there is a rise in pressure in the low pressure chamber 3, or a drop in pressure in the high pressure chamber 2, then the device acts as a check valve preventing flow from chamber 3 back to chamber 2.

  • a pump or inating hose is connected with the valve stern 20 and air or other fluid is pumped through the passages I8 and Ida into the tube and its chamber 2a.
  • the elastic strength or tension of the rubber out oi ⁇ which the sleeve I0a is made may be very strong or comparatively weak. Where it is of great strength, high pressures will be required to raise the same from the ports 5 and 6. Therefore where a high strength rubber sleeve IIIa is employed and a severe drop in pressure is caused in one of the chambers, the other chamber will only give up a small portion of its pressure to that of zhe decient chamber owing to the fact that after i comparatively small drop in pressure from the nigh pressure chamber, the strong membrane ileeve Il)n will close thus preventing the loss of my further pressure in such high pressure chamier.
  • the material of which the membrane sleeve I Ila is made may be so selected as to be of very small strength or tension in which case it will require very little pressure to lift it off its seat and away from the ports 5 and Se and thus an interchange of pressure will go on for a long time and to a comparatively low degree.

  • a port I2d leads the pressure to the exterior of the membrane sleeve Id, the space about this membrane sleeve being confined by the airtight casing I'Id.
