Abstract
A rinsing system includes: a pump control module configured to, when a hydraulic line is connected to a port that is fluidly connected to a hydraulic line of a suspension system, selectively operate a hydraulic fluid pump of the suspension system and pump hydraulic fluid from a hydraulic fluid tank of the suspension system through the hydraulic fluid pump toward the hydraulic line; and a valve control module configured to, when the hydraulic line is connected to the port and the hydraulic fluid pump is pumping hydraulic fluid, open valves of the suspension system and fluidly connect the hydraulic fluid pump with the hydraulic line.
Claims19
A rinsing system, the system comprising:
- a pump control module configured to, when a first hydraulic line is connected to a port that is fluidly connected to a second hydraulic line of a suspension system, selectively operate a hydraulic fluid pump of the suspension system and pump hydraulic fluid from a hydraulic fluid tank of the suspension system through the hydraulic fluid pump toward the second hydraulic line;
- and
- a valve control module configured to, when the first hydraulic line is connected to the port and the hydraulic fluid pump is pumping hydraulic fluid, open valves of the suspension system and fluidly connect the hydraulic fluid pump with the second hydraulic line,
- wherein the pump control module is configured to operate the hydraulic fluid pump and the valve control module is configured to open the valves in response to receipt of user input indicative of a request to rinse the hydraulic fluid pump.
A rinsing method, comprising:
- when a first hydraulic line is connected to a port that is fluidly connected to a second hydraulic line of a suspension system, selectively operating a hydraulic fluid pump of the suspension system and pumping hydraulic fluid from a hydraulic fluid tank of the suspension system through the hydraulic fluid pump toward the second hydraulic line;
- when the first hydraulic line is connected to the port and the hydraulic fluid pump is pumping hydraulic fluid, opening valves of the suspension system and fluidly connecting the hydraulic fluid pump with the second hydraulic line;
- and
- operating the hydraulic fluid pump and opening the valves in response to receipt of user input indicative of a request to rinse the hydraulic fluid pump.

- a valve control module configured to, when the first hydraulic line is connected to the port and the hydraulic fluid pump is pumping hydraulic fluid, open valves of the suspension system and fluidly connect the hydraulic fluid pump with the second hydraulic line;
- and
- a rinsing module configured to determining whether rinsing of the hydraulic fluid pump is complete based on a current of an electric motor of the hydraulic fluid pump,
- wherein the pump control module is configured to disable the hydraulic fluid pump in response to the determination that the rinsing is complete.
