Definitions

  • the invention relates to a device for supplying sealing liquid into a pneumatic tire.
  • repair kit with a portable container known.
  • This repair kit may also be suitable for introducing a sealant on a vehicle tire.
  • the repair kit is designed so that it fits in a spare tire.
  • a disadvantage of the previously known devices for sealing defective tires is that the sealing means not only closes the point to be sealed, but also leads to a bonding or deterioration of the tire valve. From the experience of examining various tire defects, it has been found that sealant residues on the valve seat lead to minor leaks and creeping pressure loss with significant impairment of the vehicle's handling. In particular, the creeping loss of air leads to a reduction in the driving stability of the vehicle and also to increased tire warming, so that a further defect or a complete loss of the tire can occur.
  • the invention has for its object to avoid the disadvantages mentioned and to provide a means for supplying sealing liquid in a pneumatic tire, which ensures a high density of the tire, does not lead to a bonding of the valve and is easy to handle.
  • the essential advantage of the invention is that the device is provided with a valve screwdriver, with which the valve insert can be removed before the introduction of the sealing liquid, so that the sealing liquid can flow unhindered into the tire.
  • the entire device has an ergonomically designed shape, so it is easy to handle and due to an inventive, elongated cylindrical shape can also be used in hard to reach places.
  • connection for supplying the sealing liquid is arranged substantially so that the liquid can flow unhindered into the pneumatic tire. This means that there is little or no fluid deflection by less than 45 °.
  • the connecting flange is provided with a latching connection according to a further embodiment of the invention.

  • the valve screwdriver is provided with a rotary handle and arranged axially displaceably on the cylindrical housing. This simplifies the unscrewing and removal of the inner part of the valve, so the valve insert from the immediate liquid flow.
  • the device is in communication with a liquid container. This connection is made through a hose.
  • the liquid container is a pressure-stable container and is supplied with compressed air by a compressor. This pressure build-up ensures that the sealing liquid is first supplied to the pneumatic tire when the entire device is activated. Then inflate the tire with compressed air to the desired pressure.
  • a receptacle for the hose and the means for supplying the sealing liquid is provided on the outer structure of the liquid container.
  • this recording can be a snap or plug connection, so that the hose, or the device is easily removable.
  • the container itself may be provided on its outside in a preferred manner with a device for releasable attachment, so that it can be locked to a vehicle or a vehicle part.
  • the container for the sealing liquid consists of a pressure-resistant plastic.
  • a screw cap provided with a removal device, where there is a dip tube is arranged, which extends to the bottom of the container or is provided axially displaceable in the screw cap.
  • the container When filling a pneumatic tire with the sealing liquid, the container can stand upright. Through the dip tube, the liquid is transported up to the emptying of the container upwards and by overpressure which is generated by an external pressure source in the container or in the container itself prevails, be discharged.
  • the dip tube may be provided for discharging the liquid, but it may also be used for supplying compressed air.
  • the container is virtually upside down, that is it is placed with the screw cap on a base. The liquid leaves this container in the region of the screw through an additional discharge opening.
  • the dip tube is designed for supplying compressed air, it may be a check valve therein to prevent discharge of liquid through the compressed air supply line.
