Definitions

  • the invention relates to a device for controlling small amounts of sand according to the preamble of claim 1.
  • the problem is that depending on the respective system pressure or Sandelle horrinn set by the injector different suction stresses in the sand and conductive area of the device.
  • the sand-conveying compressed air volume is passed completely through the injector nozzle.
  • EP 1 418 108 A1 discloses an air driven sand dispenser comprising a sand container, a compressed air source, a sand suction chamber connected to the sand container and a nozzle connected to the compressed air source, the nozzle having an air inlet, an exhaust channel and a sand suction port the sand suction space is connected directly or indirectly to the nozzle via the sand suction opening, and wherein the nozzle is provided with a sand pipe in the flow direction.
  • an air supply opens, the air supply and the nozzle are connected to the same compressed air source and means are provided for adjusting the ratio of the compressed air source to the nozzle and the air supplied to the amount of compressed air.
  • the air supply together with the throttle valve and the Y-piece, forms an accurately adjustable bypass for the airway through the nozzle.
  • the metering device for a sanding plant according to DE 29 11 075 A1 shows a tightly sealable sand reservoir.
  • a first partial air flow flows through the container and serves for drying, a second partial air flow is used for sand discharge. Both air streams are combined just before the sanding pipe.
  • US 2006/060441 A1 discloses a sanding system for a road vehicle which has a bypass line for bypassing the sand container.
  • the object of the invention is to avoid the clogging effect described in the known systems.
  • bypass line The purpose of the bypass line is to generate a controlled partial air flow from the compressed air distribution channel to the injector chamber based on a defined and controlled sandblasting function in order to ensure by a controlled vacuum reduction that when the sand flow is adjusted to a minimum sand flow setting a blockage is avoided.
  • Fig. 1 denotes the sand reservoir, from which the sand passes into the piston-controlled sand dosing and shut-off device 2, to which an injector 3 connects, in which a bypass line 4 opens. From the injector 3 leads a sand line 5 to the gap between the wheel and rail.
  • the bypass line 4 is connected via the connecting piece 4a with the injector nozzle 3a, into which also the compressed air distribution channel 6 opens (FIGS. 2 and 3).

Abstract

Équipement de commande de quantités de sable pour des véhicules ferroviaires en utilisant un équipement (2) de dosage et d'isolement de sable commandé par piston pour des diffuseurs de sablière pour véhicules ferroviaires. Un injecteur (3) doté d'une buse d'injecteur (3a) est raccordé à l'équipement (2) de dosage et d'isolement de sable. Une conduite de dérivation (4) débouche dans l'injecteur (3). En raccordement au branchement d'air comprimé, la répartition de l'air comprimé sur l'injecteur (3) s'effectue par l'intermédiaire d'un canal d'air comprimé à soupape.
