摘要： A method of maintaining a backpressure of a fluidic product is provided. The method includes pressurizing a first reservoir to a first predetermined pressure level using compressed air, delivering the fluidic product to the pressurized first reservoir until a current level of the fluidic product in the first reservoir reaches a first predetermined level, pressurizing a second reservoir to a second predetermined pressure level using the compressed air, delivering the fluidic product to the pressurized second reservoir until a current level of the fluidic product in the second reservoir reaches a second predetermined level, and controlling the backpressure of the fluidic product using the first reservoir and the second reservoir such that a discharge flow of the fluidic product is continuous.

摘要： An air management system and method are provided. The system includes a pressurized air source. A manifold block is coupled to the pressurized air source and includes a plurality of suspension valves in fluid communication with the pressurized air source and each defines a suspension orifice of a first diameter for controlling air flow to and from a plurality of air springs. A manifold pressurization valve is in fluid communication with the plurality of suspension valves and the pressurized air source and defines a manifold pressurization orifice of a second diameter that is less than the first diameter of the suspension orifice for opening under high pressure to allow pressurized air into the manifold block. An electronic control unit controls the manifold pressurization valve and the plurality of suspension valves to equalize a high pressure differential across the plurality of suspension valves from the plurality of air springs.

摘要： A pneumatic suspension system for a vehicle, in which the pneumatic suspension system includes a supply tank, a first set of air springs positioned on a first side of the vehicle; a second set of air springs positioned on a second side of the vehicle, and a dual-action dynamic valve positioned between the first set of air springs and the second set of air springs. The dual-action dynamic valve is connected to the supply tank, the first set of air springs, and the second set of air springs by a series of air hoses. The dual-action dynamic valve is adapted to supply air to either one of the first set of air springs or the second set of air springs while simultaneously exhausting air from the other one of the first set of air springs or the second set of air springs.

摘要： A vehicle-height control system includes: a vehicle-height control actuator; a pressure-medium supply and discharge device configured to supply and discharge a pressure medium; and a vehicle height controller configured to control a vehicle height by controlling the pressure-medium supply and discharge device. The pressure-medium supply and discharge device includes a compressor and a tank configured to contain a pressure medium supplied from the compressor. The vehicle height controller includes a down controller configured to operate the compressor to discharge and supply the pressure medium from the vehicle-height control actuator to the tank to lower the vehicle height when a tank pressure is less than a set pressure. The down controller is configured to discharge the pressure medium from the vehicle-height control actuator to an outside to lower the vehicle height when the tank pressure is greater than or equal to the set pressure.
