Abstract

A system for removing moisture from compressed air in pneumatic brake equipment including an air compressor having an outlet pneumatically connected to an inlet of a cooler. The cooler having an outlet pneumatically connected to a pair of electromagnetic multi-way valves. Each of the valves includes a supply section and an exhaust section. A pair of drying cylinders have inlets selectively pneumatically connectable to the supply and exhaust sections of the respective pair of electromagnetic multi-way valves. An air reservoir has its inlet pneumatically connected to the outlets of the drying cylinders via a respective check valve. A governor is pneumatically connected to the air reservoir for sensing the pressure level in the air reservoir. A control circuit is electrically connected to the pair of electromagnetic multi-way valves and the governor for causing the drying cylinders to switch to the drying and regenerating state at a preset time only when the air compressor is continuously operating for a time longer than the preset time and to remain in the same positions that they were in just prior to the stopping of the air compressor.
