- Spring - pressure relief Pilot Exhaust Valve A solenoid operated pilot exhaust valve is connected to the air delivery gallery, downstream of the air dryer. The pilot valve, When the solenoid is energised, pilot air moves the exhaust valve plunger, allowing pressurised air from the air springs The solenoid has a resistance value of 4 Ohms at a temperature of 20°C (68°F). Exhaust Valve The exhaust valve has three functions. It operates in conjunction with the pilot exhaust valve to allow air to be exhausted The valve also protects the system from over-pressure. The valve is connected into the main pressure gallery which is 2 (22.0 to 27 bar gage). The minimum pressure in the system is also controlled by the exhaust valve to ensure that, even when deflated, the air 2 (1 bar gage) with respect to atmosphere. This protects the air spring by ensuring it can still 'roll' over the piston without creasing. Electric Motor The electric motor is a 12V dc motor with a nominal operating voltage of 13.5V. The motor drives a crank which has an The motor is fitted with a temperature sensor on the brush PCB assembly. The sensor is connected to the air suspension Compressor The compressor comprises a motor driven connecting rod and piston which operate in a cylinder with a cylinder head. The Air Dryer The air dryer is an integral part of the air supply unit. The air dryer contains a desiccant which absorbs moisture. Pressurised When the air is exhausted from the system, the returning air is passed through the air dryer, regenerating the air dryer by The air dryer is an essential component in the system ensuring that only dry air is present in the system. If moist air is AIR RESERVOIR |
