Definitions

  • the present invention relates to a device for stabilizing air-pressure in a mechanically enclosed environment. More particularly the present invention relates to a vacuum relief valve and / or air breather valve in a mechanically closed environment.
  • the present invention is therefore designed in particular to substitute the vent hose assembly and breather vent and thereby which controls and dynamically regulates the pressure or vacuum of the area.
  • Breather Vents permit free exchange of filtered air for gear cases, crank cases vented to atmosphere. Rugged and corrosion resistant, some breather vent models can be adapted to incorporate oil separators for special applications.
  • the basic model of breather vent ppsses air through a filter media stopping solid particles.
  • a micro metal filter (100 micrometers or finer) is an option for use in areas where high temperature, corrosive vapors or fine filtration issues exist.
  • crankcase pressure In most internal combustion engines, it is desirable to maintain the pressure within the crankcase at a level equal to or slightly less than atmospheric pressure to reduce leaks through gaskets and seals from the crankcase to the atmosphere.
  • blow-by gases are emitted in the crankcase as a result of leaks of the air-fuel intake mixture and combustion gases through the clearances around piston rings during the compression, combustion and/or exhaust cycles. Because of these blow-by gases, the internal crankcase pressure will inherently rise promoting oil leakage from the crankcase to the surrounding environment.
  • a transmission fluid Since are often subjected to extreme temperature variations, it is desirable for a transmission fluid to function somewhat consistently over the vehicle operating range. In addition to variations in ambient operating temperatures, a transmission fluid is also subjected to heat generated by friction produced by the numerous rotating components. This temperature fluctuation is manifested as a change in viscosity of the transmission fluid. The change in viscosity may pose a number of challenges in designing a mechanical transmission for consistent performance over a typical operating range.
  • a transmission breather which provides pressure equalization while reducing or eliminating unnecessary transmission fluid expulsion from the breather during normal operation of the transmission without allowing easy entry of external contaminants into the transmission. It is also desirable to provide a breather which reduces or eliminates fluid escape in the form of vapor. It is also desirable to provide a breather which comprises only a few parts, which can be easily manufactured and which can be easily installed in the transmission with a top-drivable tool, such as a socket wrench or a screwdriver. It is also desirable to provide a breather which is designed to withstand the types of impacts which could occur over the lifetime of the breather and which is corrosion resistant.
  • the present invention discloses vacuum relief valve and / or air breather valve for a mechanically closed environment.
  • the present invention is therefore designed in particular to substitute the vent hose assembly and breather vent and any other existing devices which controls and dynamically regulates the pressure or vacuum of a mechanically enclosed environment.
  • a unit assembly which is a compact engineered product designed to stabilize air- pressure in a mechanically enclosed environment such as a gear box, transmission, differential etc.
  • an unit assembly which does not allows any spillage of lubricant from gearbox /differential chamber etc., in case the automobile rolls and settles as an add angle, thereby ensuring no possible fire hazard (possible, for example, if the leaking lubricant comes in contact with silencer of the vehicle, which due to use of catalysts assume high temperature).
  • a unit assembly which functions as a air lock and arrests water from entering into the enclosure.
  • a plug for the exhaust chamber and it holds the valve and spring in place which further allows hot air to escape and also allows water to the chamber in case the axle is submerged inside water.
  • a moulded body comprising two circular chambers fitted with exhaust and intake values and two other chambers to accommodate water sucked inside the vent in case the gear box / differential is submerged in water and develop suction pressure.
  • a voluminous cap unit assembly wherein the increased height ensures additional accumulation of water (if submerged in water) before it enters the chamber.
  • Another object of the present invention is to provide a vent assembly that is easy to construct, easy to instal, inexpensive and versatile.
  • Yet still another object of the instant invention is to provide a vent assembly which inhibits contaminants from entering the space of the container.
  • Still a further object of the immediate invention is the provision of inhibiting personal injury with a vent when the liquid earned within the container is toxic.
