Abstract
A tubular channel is disposed in a path of air that flows from an inlet to a dirty side. The cross sectional area of the tubular channel is smaller than the cross-sectional area of the inlet. A dust outlet is disposed in a wall in a path of the air that flows out of the exit of the tubular channels to the dirty side. The dust outlet extends through the wall of the air cleaner from the inside to the outside. As the air blasts out of the dust outlet, dust in the air cleaner is discharged to the outside.
Claims8
An air cleaner that has an inside divided into a dirty side and a clean side by an element, filters out dust contained in air drawn in from the outside at the dirty side with the element, and delivers the air that has been clarified to the clean side, the air cleaner comprising:
- an inlet through which the air is drawn in from the outside;
- a tubular channel that is disposed to define a path of the air flowing from the inlet to the dirty side, the tubular channel having a cross-sectional area smaller than a cross-sectional area of the inlet;
- a dust outlet that is formed in a path of the air having passed through the tubular channel and flowing to the dirty side, the dust outlet extending through the air cleaner from the inside to the outside;
- and
- an air outlet that communicates with the clean side and discharges the air that has been clarified to the outside,
- wherein dust in the air cleaner is discharged to the outside together with the air that blasts out through the dust outlet.
An engine comprising:
- an air cleaner that has an inside divided into a dirty side and a clean side by an element, filters out dust contained in air drawn in from the outside at the dirty side with the element, and delivers the air that has been clarified to the clean side, the air cleaner including
- an inlet through which air is drawn in from the outside;
- a tubular channel that is disposed to define a path of the air flowing from the inlet to the dirty side, the tubular channel having a cross-sectional area smaller than a cross-sectional area of the inlet;
- a dust outlet that is formed in a path of the air having passed through the tubular channel and flowing to the dirty side, the dust outlet extending through the air cleaner from the inside to the outside;
- and
- an air outlet that communicates with the clean side and discharges the air that has been clarified to an air intake of the engine,
- wherein the dust in the air cleaner is discharged to the outside together with the air that blasts out through the dust outlet.
