Abstract
An intake duct for an air intake system of a work vehicle is disclosed. The intake duct may generally include a body defining an air passage extending between an intake end and an outlet end. The body may further define a recessed intake at the intake end including a first side section and a second side section. Each of the first side section and the second side may define at least one side opening for directing air into the air passage. In addition, the recessed intake may include a deflector projecting outwardly from the first and second side sections. The deflector may be configured to shield the air passage from water directed towards the recessed inlet.
Claims9
An intake duct for an air intake system of a work vehicle, the intake duct comprising:
- an elongated body defining an air passage extending between an intake end and an outlet end, the elongated body further including
- a recessed intake at the intake end including a first side section and a second side section, at least one of the first side section or the second side defining an opening for directing air into an air passage, the recessed intake further including
- a deflector projecting outwardly from the first and second side sections, the deflector being configured to shield the air passage from water directed towards the recessed inlet;
- the deflector comprising at least a first deflector portion extending between a top edge and a bottom edge and at least a second deflector portion extending between a top edge and a bottom edge, the first deflector portion being flared outwardly at its bottom edge relative to the top edge of the second deflector portion such that a first deflector opening which is in communication with the air passage is defined between first and second deflector portions, wherein the bottom edge of the first deflector portion is horizontally aligned with or disposed vertically below the to edge of the second deflector portion, the first deflector portion configured to deflect horizontally driven water downward due this alignment with the top edge of the second deflector;
- and
- a screen covering at least the recessed intake and the first deflector portion and the second deflector portion, the deflector projecting outwardly from first and second side sections in the direction of the screen, and the screen providing at least a partial deflection of water away from the elongated body of the intake duct.
An air intake system for a work vehicle, the air intake system comprising:
- an elongated body including an intake duct comprising an air passage extending between an intake end and an outlet end;
- including
- a deflector projecting outwardly from the first and second side sections, the deflector being configured to shield the air passage from water, the deflector comprising
- at least a first deflector portion extending between a top edge and a bottom edge and at least a second deflector portion extending between a top edge and a bottom edge, the first deflector portion being flared outwardly at its bottom edge relative to the to edge of the second deflector portion such that a first deflector opening is defined between first and second deflector portions, the first deflector opening in communication with an air passage which extends from the intake end through the outlet end, wherein the bottom edge of the first deflector portion is horizontally aligned with or disposed vertically below the top edge of the second deflector portion, the first deflector portion configured to deflect horizontally driven water downward due this alignment with the top edge of the second deflector;
- and
- a screen covering at least the deflector and connected to at least a portion of the elongated body, the deflector projecting outwardly in the direction of the screen.
