Claims33
In a lubricator apparatus, improved structure for entraining lubricant in a gas stream flowing within a gas flow path comprising:
- a reservoir for containing a volume of lubricant which is capable of forming a dispersion of liquid lubricant particles;
- means for entraining gas as within such a volume of lubricant;
- such volume of lubricant including a free surface, and said reservoir including a space adjacent such free surface and extending intermediate such free surface and such gas flow path;
- said free surface being adapted to allow said gas to escape from such volume of lubricant thereby creating a dispersion of such liquid lubricant particles within said space;
- means for impelling such liquid lubricant particles through said space toward such gas flow path;
- filter means disposed within said space and operable to capture such liquid lubricant particles larger than a selected size and to allow such liquid lubricant particles smaller than said selected size to pass through said filter means and continue moving toward such gas flow path;
- and
- means for entraining at least some of such liquid lubricant particles which pass through said filter means within the gas stream flowing in such gas flow path.
In a lubricator apparatus, improved structure for entraining liquid lubricant in a gas stream flowing in a gas flow path comprising:
- a reservoir for containing a volume of lubricant which is capable of forming a dispersion of liquid lubricant particles;
- means for entraining gas within such a volume of lubricant;
- such volume of lubricant including a free surface, and said reservoir including a space adjacent such free surface and extending intermediate such free surface and such gas flow path;
- such free surface being adapted to allow said gas to escape such volume of lubricant thereby creating a dispersion of liquid lubricant particles within said space;
- means for impelling said liquid lubricant particles through said space toward such gas flow path;
- a filter media body disposed within said space and including an encompassing wall surrounding a through opening which forms a portion of such gas flow path;
- said encompassing wall having an exterior wall portion which is exposed to said space to permit at least some of such liquid lubricant particles moving within said space to pass through said encompassing wall from said space and into such gas flow path to become entrained within the gas stream flowing within such gas flow path.
In a lubricator apparatus having a gas flow path including a restricted throat portion through which a stream of gas flows and within which a particle media is entrained in such gas stream, the improvement comprising:
- at least a portion of said restricted throat portion of such gas flow path being formed by a filter media body having an encompassing wall surrounding a through opening which forms said portion of such gas flow path, and said encompassing wall having an exterior wall portion and a property of controlled permeability to permit such particle media to pass through said encompassing wall from said exterior wall portion into said restricted throat portion to allow such particle media to become entrained in such gas stream as it flows through said restricted throat portion.
In a lubricator apparatus having a gas flow path with a restricted throat portion through which a stream of gas flows and within which a particle media is entrained in such a gas stream, the improvement comprising:
- said restricted throat portion being formed at least partially by a permeable means having an interior wall which at least partially encompasses a longitudinally extending part of said restricted throat portion to form a peripheral interior wall portion thereof, and said permeable means being adapted to be exposed to a source of such a particle media whereby such particle media is able to move through said permeable means and traverse said interior wall to pass into said restricted throat portion for entrainment in such a gas stream flowing through said restricted throat portion.
