Definitions

  • the present invention relates to a suction device for a pre-cleaning device in conjunction with a fan cowling, as they are often used for internal combustion engines in vehicles.
  • the present invention relates to a device which is used for a pre-cleaning device for pre-cleaning the combustion air of an internal combustion engine.
  • the present invention relates to a suction device, which provides a vacuum or a vacuum to such a pre-cleaning device.
  • Air intake systems for internal combustion engines of agricultural or industrial utility vehicles usually have pre-purification devices with which dirt particles are removed from the intake air before the intake air reaches the air filter.
  • Many pre-cleaning facilities require a negative pressure or a vacuum in order to extract dirt particles from the fresh air entering the air intake system or to clean the fresh air from dirt particles.
  • Exhaust systems were used to provide the required vacuum.
  • such an exhaust system entails a restriction in the exhaust gas of the internal combustion engine, increases the noise emission and the cost of an exhaust muffler and / or an exhaust pipe.
  • a check valve is required to prevent backflow of high temperature gases into the pre-cleaner.
  • hose connectors that are suitable for high temperatures must be used.
  • a fan cowl suction device is usually formed by an opening in the fan cowl, which is connected by means of a hose connection with the pre-cleaning device.
  • a disadvantage of such a suction device is that this additional hose connections and hose clamps are needed.
  • Modern agricultural tractors or other utility vehicles may require an elongated fan shroud to fill the space between a radiator and a fan.
  • An example of such a system is in US 5427502 shown.
  • the object underlying the invention is seen to provide and further develop a suction device of the type mentioned, by which the above-mentioned problems are overcome.
  • a suction device should be specified and further developed, which can be produced more cheaply and which preferably has fewer individual parts.
  • Such a suction device should be particularly compatible with known or existing manufacturing and manufacturing techniques.
  • the suction device according to the invention is suitable for a pre-cleaning device in conjunction with a fan cowl.
  • the pre-cleaning device has a suction port.
  • the fan cowl is located between a fan and a radiator.

  • the pre-cleaning device can be attached to the fan cowling in such a way that the suction port is in direct communication with the port via the portal.
  • the required negative pressure or the required vacuum for sucking for the pre-cleaning device is provided by a generated by the fan air flow or air flow through the channel.
  • a fan cowl which has a suction device integrated therein.
  • the fan cowling has an upper and a lower section.
  • the upper portion is formed complementary to the lower portion, so that in the assembled state, a channel between the fan and the cooling module or the radiator of the vehicle is formed.
  • the upper portion of the fan shroud has a channel formed by an air duct section in the fan shroud and a similar air duct section in a duct cover.
  • the channel is formed when the channel cover is fitted to the upper portion of the fan cowl.
  • a first end of the channel terminates at an aperture located at the end of the fan cowl near the fan.
  • a second end of the channel is formed bent upward and forms a nozzle or a portal on the upper side of the Channel cover.
  • a pre-cleaning device has an air inlet and an air outlet and is pressurized via a suction with negative pressure.
  • the suction port is located at the portal or nozzle of the channel shroud.
  • the suction port is directly connected to the portal or the nozzle of the channel cover, without intervening, for example, a hose connection is required.
  • the suction port is thus in communication with the air passage and the aperture located in the fan shroud.
  • the vacuum required to operate the aspirator is provided by the air movement generated by the fan, the movement of air between the air inlet of the prepurifier and the aperture located in the fan shroud being via the aspiration port and the air channel. Since the pre-cleaning device is directly adaptable or adaptable to the air duct, no additional vacuum hoses or hose clamps are required. Therefore, space under a hood can be saved in a particularly advantageous manner.
