PNEUMATIC CIRCUIT, HAVING A SIMPLE CONSTRUCTION AND CAPABLE OF REDUCING THE COST

摘要

PURPOSE: A pneumatic circuit is provided to simplify a circuit construction since even if the size of a valve, forming a garage height control circuit, is reduced, there is no impact on operation realization.;CONSTITUTION: An air suspension comprises a reservoir(1), an air spring(30), a solenoid valve(20), a cork valve(5) and a pneumatic circuit. The reservoir fills the compressed air through a compressor(3). The air spring is installed on each vehicle wheel and maintains the adequate air pressure. The solenoid valve is controlled by ECU and controls the air pressure of the air spring. The cork valve supplies the compressed air of the reservoir to an external instrument, such as a tire(T). The pneumatic circuit is connected from the reservoir to the air spring to circulate the compressed air.;COPYRIGHT KIPO 2011
