Air compression device

Abstract

The present application discloses an air compression device, including a housing in which an air compressor is stored, the air compressor being configured to generate compressed air; and a filter through which air passes, the air being sucked into the housing. The filter may include a plate member having a first main plate portion provided with air holes through which the air passes. A surface of the first main plate portion is oriented in a first direction, the air holes extending through the plate member in a second direction intersecting with the first direction so as to change a flow direction of the air.

What is claimed is: 
     
         1 . An air compression device, comprising:
 a housing in which an air compressor is stored, the air compressor being configured to generate compressed air; and   a filter through which air passes, the air being sucked into the housing,   wherein the filter includes a plate member having a first main plate portion provided with air holes through which the air passes, and   wherein a surface of the first main plate portion is oriented in a first direction, the air holes extending through the plate member in a second direction intersecting with the first direction so as to change a flow direction of the air.   
     
     
         2 . The air compression device according to  claim 1 ,
 wherein the filter includes a second main plate portion aligned with the plate member in a third direction different from the first and second directions, and   wherein the second direction has a first intersection angle with an imaginary plane which perpendicularly intersects with the first direction.   
     
     
         3 . The air compression device according to  claim 2 ,
 wherein the air holes in the first main plate portion include a first air hole, and a second air hole aligned with the first air hole in a fourth direction along the surface of the plate member,   wherein the second main plate portion includes a third air hole extending in a fifth direction having a second intersection angle with the fourth direction, and a fourth air hole aligned with the third air hole in the fifth direction,   wherein each of the first and second air holes is an oblong hole extending in the fourth direction, and   wherein each of the third and fourth air holes is an oblong hole extending in the fifth direction.   
     
     
         4 . The air compression device according to  claim 3 , wherein the second intersection angle is 90 degrees. 
     
     
         5 . The air compression device according to  claim 4 ,
 wherein the second direction is parallel to a running direction of a vehicle to which the air compression device is attached, and   wherein the third direction is parallel to a vertical direction of the vehicle.   
     
     
         6 . The air compression device according to  claim 1 , further comprising:
 a louver facing the first main plate portion,   wherein the louver appears on an outer surface of the housing and allows passage of the air.   
     
     
         7 . The air compression device according to  claim 1 , further comprising:
 a cooling fan which cools the air compressor and the compressed air in the housing,   wherein the air compressor and the cooling fan are aligned with the filter.   
     
     
         8 . The air compression device according to  claim 5 ,
 wherein the vehicle includes a vehicle side surface along the running direction,   wherein the housing includes a housing side surface along the vehicle side surface, and   wherein the filter is attached to the housing side surface.
