Abstract
A guard for a space access device is configured to output air flow through a distal end portion thereof. The guard includes q housing having a proximal end opening, a distal end opening, and a filter portion positioned between the proximal and distal end openings. The filter includes a first plate having a first opening therethrough and a second plate having a second opening therethrough. When the first plate is overlaid in contact with the second plate, this forms an aperture that extends through both the first and second plates.
Claims17
A guard for a space access device configured to output air flow through a distal end portion thereof, said guard comprising:
- a housing having a proximal end opening and a distal end opening and a wall having an internal wall surface and an external wall surface, wherein said proximal end opening is configured to be placed nearer than said distal end opening to the output of air flow from the distal end portion of the space access device;
- a filter portion positioned in said housing between said proximal and distal end openings, said filter portion comprising at least one aperture to allow air to pass from said proximal end opening of said housing to said distal end opening;
- a berm contacting a perimeter of said filter portion and extending toward a distal end of said guard;
- and
- a passageway having a first opening opening to a space proximal of said filter portion and internal of said internal wall surface at a location where said berm contacts said perimeter of said filter portion, said passageway extending through said wall of said housing, and having a second opening at an end opposite said first opening, said second opening opening into said external wall surface at a location distal of said filter portion.
A guard for a space access device configured to output air flow through a distal end portion thereof, said guard comprising:
- a housing having a proximal end opening and a distal end opening, wherein said proximal end opening is configured to be placed nearer than said distal end opening to the output of air flow from the distal end portion of the space access device;
- a filter portion positioned in said housing between said proximal and distal end openings, said filter portion comprising at least one aperture to allow air to pass from said proximal end opening of said housing to said distal end opening;
- and
- a berm contacting a perimeter of said filter portion and extending toward a distal end of said guard;
- wherein said filter portion comprises:
- a distal surface, a proximal surface and a thickness, a first opening formed in said distal surface and extending into a first portion of said thickness;
- and
- a second opening formed in said proximal surface and extending into a second portion of said thickness;
- wherein said first opening overlays said second opening to form said at least one aperture, said at least one aperture extending through said thickness;
- wherein said first opening has a first cross-sectional area, said second opening has a second cross-sectional area and said aperture has a third cross-sectional area;
- and
- wherein said first cross-sectional area is greater than said third cross-sectional area and said second cross-sectional area is greater than said third cross-sectional area.
