17/411112

Inventors:

- Madison IN, US
Jason Stewart - Harvest AL, US

International Classification:

F16H 57/04
F16H 57/02

Abstract:

A portal gear box assembly for an all-terrain vehicle includes: a portal gear box housing a set of gears and linking an axle to an output shaft; a lubricating oil contained in the gear box; and a fluid circulation loop that circulates a cooling fluid to a cooling location outside the gear box. The cooling fluid may be a lubricating oil. The fluid circulation loop may include a pump and/or a filter. The cooling location may pass the fluid through a structure such as a radiator or other cooler. The circulation loop and/or any radiator/cooler, filter, or pump contained therein, may serve a single portal gear box, or may serve two or more portal gear box assemblies.

Inventors:

- Huntsville AL, US
Jason T. Stewart - Harvest AL, US

Assignee:

CDS-John Blue Company - Huntsville AL

International Classification:

F04D 29/42
F04D 29/22
F04D 15/00
F04D 9/02
F04D 13/02

Abstract:

A reconfigurable pump includes a housing with inlet and outlet openings. An inlet adapter is mounted on the housing and includes an inlet passage communicating with the inlet opening. The inlet adapter is removably mounted on the housing and can be removed and repositioned for reconfiguring the pump between low-inlet and high-inlet configurations. In a low-inlet configuration the inlet passage is generally aligned with an impeller rotatably mounted in the housing. A check valve comprising a flapper valve is provided in the low-inlet configuration and prevents backflow. The flapper valve is removable for configuration in a high-inlet configuration with the inlet passage located generally above the impeller level. The inlet adapter can readily be repositioned from outside the pump housing between its low-inlet anti-inlet configurations.

US Classification:

239722, 13762546

Abstract:

An orifice selector module for use with flow gauges in a sprayer environment. The orifice selector module is retrofit into existing or new flow gauge assemblies and is placed in line between the spray nozzles and the flow gauges. The orifice selector module includes a rotatable cap which rotates a rotor which in turn rotates an orifice plate which features numerous orifices of different sizes. These orifices can be switched on the fly manually by the vehicle operator to increase or decrease flow through a particular hose from a particular flow gauge.
