Definitions

  • the invention relates to a motor-operated pressure valve for cabins of railroad cars or the like, in particular for passenger cabins of passenger cars.
  • DE-B 1 680 792 describes a device for air conditioning rail vehicles, in which a mixture of fresh air and recirculated air can be controlled by a valve which has a slotted valve plate which is movably supported on a guide plate.
  • An electric hole slide control for air conditioning systems of this type is known from DE-B 2 038 912, the sensors causing the hole slide position react to the outside temperature and the desired inside temperature.
  • Plate valves of a general type are known from EP-A 147 562.
  • the invention is therefore based on the object of providing a device of the type mentioned which reliably avoids such disturbing pressure fluctuations in the cabin, even at high pressure differences.
  • the invention solves this problem by training features of claim 1.
  • a pressure valve with these training features enables extremely large opening cross-sections for the air flow and can be tightly closed and fully opened in a very short time using a motorized adjustment drive.
  • good rigidity can be achieved because the guide plates stiffen or support the valve plate from both sides.
  • the use of the valve plate and its arrangement between two guide plates also enables relatively wide overlap areas at the edges for sealing, so that high tightness can be achieved over long periods of time when the pressure valve is closed and can also be maintained in the event of wavy pressure fluctuations with high overpressure and high vacuum. This enables the corresponding requirements for air-conditioned cabins for passenger coaches to be met with low leakage coefficients. The correct functioning of the pressure valve is maintained even if the high pressure fluctuations occur during the closing process.
  • the small play transverse to the plane of the plate leads to a practically frictionless movement of the valve plate with balanced pressure between the inside and the outside of the cabin, so that low driving forces are sufficient, and on the other hand this play is used practically, so that the valve plate is closed by both when the pressure valve is closed internal overpressure as well as an external overpressure with this sealing material is pressed firmly against the respective supporting guide plate. Nevertheless, the valve plate remains able to move even at high pressure differences due to the low coefficient of friction of this coating material.
  • the valve plate has one or more pins which extend transversely to the plane of the valve plate and engage in slots in a guide plate, the length of which limits the path of movement of the valve plate relative to the guide plates.
  • the motor drive which advantageously consists of a pneumatically actuated piston-cylinder unit, can be articulatedly connected to one of these pins or also to several of the pins.
  • This piston-cylinder unit can be controlled in known manner by known sensors which convert the pressure differences into switching pulses for the motor drive.
  • the pressure differences at which switching impulses turned out are to be solved, can be predetermined in a known manner.
  • the pressure valve which can be built into the wall of a passenger cabin of a passenger car or the like consists of the inner valve plate 1 and the two outer guide plates 2 and 3, which support the valve plate 1 from both sides.
  • the valve plate 1 In the valve plate 1 there are slots 4 running parallel to one another, and likewise the guide plates 2 and 3 have slots 5 and 6 running parallel to one another at overlapping locations, the width of which corresponds approximately to the width of the slots 4.
  • the width of the webs between the slots 4 of the valve plate 1 is, however, considerably larger than the width of the slots 5 and 6 in the guide plates 2 and 3, so that when the pressure valve is closed, which corresponds to the illustration in the drawing figures, a considerable material coverage is achieved good tightness of the pressure valve arises.
  • the valve plate 1 is arranged to be movable between the guide plates 2 in its plane transverse to the longitudinal direction of the slots 4, 5 and 6, with a pin 7 or even several pins limiting this movement of the valve plate 1 with respect to the guide plates 2 and 3.
  • the pin 7 is fixed on the valve plate 1 and extends transversely to the plane of the cover plate 1 in an elongated hole 8, the ends of which form stops for the pin 7.
  • this pin 7 or several such pins are points of attack for the motor drive for closing and opening the pressure valve.
  • this motor drive consists of a piston-cylinder unit, the piston rod 9 of which is articulated to the pin 7 and the cylinder 10 of which is fixed relative to the guide plate 3.
  • the sensor control for this motor drive 9, 10 was not shown in the drawing and does not form the subject of the invention.
  • valve plate 1 is shown with a slight play transversely to the plane of the plate between the two guide plates 2 and 3 results from the drawing figures 2 and 3.
  • These coatings 11 are designated in FIG. 3 and can be recognized in FIG. 2 by the somewhat thicker lines.
  • the described construction of the pressure valve can also be duplicated, so that a plurality of valve plates 1 are arranged in parallel next to each other between two guide plates 2. This creates a multiple seal with a labyrinth at each individual through slot 4 of the valve plates when the pressure valve is closed.
