  • Patent number: 10875376
    Abstract: An air suspension system includes air suspensions (1, 2) performing vehicle height adjustment in response to supply and discharge of air, a compressor (3) compressing air, a tank (4) storing compressed air, a first passage (6) connecting between the delivery side of the compressor and the tank, and a second passage (7) connecting between the delivery side of the compressor and the air suspensions. A first dryer (10) is provided in the middle of the first passage to dry air flowing through the first passage. A second dryer (11) is provided in the middle of the second passage to dry air flowing through the second passage. Thus, compressed air generated from ambient air sucked in by the compressor can be dried by the second dryer and supplied directly into the air chambers of the air suspensions.

  • Patent number: 10800223
    Abstract: An air suspension system includes a tank, a tank-side open/close valve, an air suspension-side open/close valve, a system portion, and the like. The system portion includes a compressor, an air drier, and a first passage and a second passage provided between the tank-side open/close valve and the air suspension-side open/close valve in parallel, a discharge valve, a tank-side control valve, an air suspension-side control valve, and the like. Due to this configuration, the air suspension system regenerates the air drier by opening the discharge valve to thus cause the air in the second passage to flow from an opposite side toward one side of the air drier when no power is supplied to the tank-side control valve and the air suspension-side control valve.

  • Publication number: 20190100070
    Abstract: Provided is a closed type air suspension apparatus requiring no complicated control and capable of simplifying the overall structure. The air suspension apparatus includes a tank storing air, a return valve returning compressed air in an air suspension to the tank, a discharge valve discharging compressed air in the tank to the outside through an intake-discharge port when the compressed air between the intake side of a compressor body and the tank reaches a first value or more, and an intake valve opening when the pressure of the air between the intake side of the compressor body and the tank is at a second value less than the first value, thereby allowing the atmosphere (air) to be taken in from the intake-discharge port. The compressor body of a compressor compresses air including the compressed air in the tank.

  • Patent number: 6231321
    Abstract: This invention pertains to an air compressor having a cylinder head with an air supply passage communicating with a discharge hole. First and second exhaust passages are arranged in parallel between the air supply passage and an exhaust port. A pilot-operated switching valve is located at an intermediate position in the first exhaust passage. A solenoid-operated exhaust valve is located at an intermediate position in the second exhaust passage. The solenoid-operated exhaust valve is selectively opened or closed by an externally supplied electric current, thereby controlling a pilot pressure applied to a valving element of the pilot-operated switching valve. The valving element is rested on or separated from a valve seat by the pilot pressure. The compressed air discharge speed can be increased without increasing the size of the cylinder head, and vehicle height adjustment, for example, can be made in a reduced period of time.

  • Patent number: 6074177
    Abstract: The present invention provides an air compressor which includes an air drier filled with a drying agent and having a first passage for supplying compressed air to one air supplied part while absorbing moisture from the compressed air by passing the compressed air through the drying agent (27) and a second passage (28a) for supplying the compressed air to another air supplied part without passing the compressed air through the drying agent. The air supplied through the first passage returns through the same passage to dry the drying agent.
