Definitions

  • the present disclosure deals with advancement in stabilizing air-pressure in a mechanically enclosed environment such as a gear box / differential/ transmission etc. More particularly the present invention relates to a vacuum relief valve and / or air breather valve in a mechanically closed environment with single / twin ball valve with one vent. The present invention is therefore designed in particular to substitute the complex 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 passes 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 the gear boxes 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.
  • Bridging occurs when the transmission fluid spans the opening of the vent or breather due to the cohesion tension of a viscous fluid. As the transmission warms up, the pressure increases within the transmission creating bubbles within the tube or breather which forces the fluid to be expelled unnecessarily from the transmission.
  • a Japanese application JP10002223A2 made by ISUZU MOTORS LTD discloses air vent valve for engine.
  • the application provides a solution with an air vent valve with a structure and work simplified and facilitated, to prevent molding sand and foreign matter from accumulating in a valve case, accordingly prevent a ball valve unit from sticking, and smoothly surely move to a valve seat of the ball unit by cooling water after venting air.
  • a lower part of a valve case receiving the ball valve unit is widely opened with a support part left of a ball valve unit, also in a side wall above the ball valve unit in the valve case an air bleed hole is formed, molding sand and foreign matter in the engine, even when infiltrating in the valve case, can be released to the outside from a lower end opening part of the valve case, sticking of the ball valve unit is prevented, the valve unit can be always normally operated.
  • the ball valve unit is smoothly surely moved upward, to be made seatable in a valve seat, the engine after starting can be quickly warmed up, also even a structure and work are simplified and facilitated.
  • an US application No. US5653258 made by Behr-Thomson GmbH & Co. discloses a vent valve.
  • the vent valve for a thermostatic valve of a coolant circuit of an internal combustion engine has a ball with a radius and a diameter and serving as a sealing element, and a one-piece metal cage for the ball.
  • the cage has a pot-shaped part with an inside diameter larger than the diameter of the ball, and a bottom having a valve opening surrounded by an outwardly projecting neck.
  • the cage is shaped in one piece from an originally flat metal sheet by stamping, deep-drawing, and pressing, and the pot-shaped part has a height approximately the radius of the ball, and an edge abutted by a plurality of uniformly distributed tabs located on an axial extension of the pot-shaped part, the tabs having inwardly bent ends to retain the ball in the cage with play, the length of the tabs being greater than or equal to the height of the pot-shaped part.
  • 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 by a air breather vent assembly with single vent and single / twin ball valve.
  • the vent is designed with single / twin ball valve since it allows free passage of air in and out of the chamber while prevents water ingestion and spillage of lubricant into and out of an enclosure in adverse circumstances.
  • [0014] As per another object of the present invention is to introduce vacuum limiting assembly, which controls and dynamically adjusts the amount of vacuum of an internal combustion engine / gear box /transmission /differential etc.
  • 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.
  • a unit assembly which meets all the requirements of the assemblies (gear box etc), so effectively, besides bestowing tremendous cost reduction benefit that the manufactures / user would appreciate, world-wide.
  • a unit assembly which is, threaded for an easy installation over the gear box, differential, transmission assemblies, etc.
  • an air breather vent assembly with single vent and single / twin ball valve_operable for a mechanically enclosed environment comprising of a body with a circular centrally oriented exhaust and intake chamber single / twin ball valves in separate housings; a cap to cover the said body and house air filter fibers for intake of fresh air and oil filter for exhaust air impregnated with air vapour.
  • 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).
