Document Type and Number:

WIPO Patent Application WO/2018/105711

Kind Code:

A1

Abstract:

The present invention provides an air supply system capable of constraining increase in the number of wires or connectors. The air supply system is provided with: a check valve (19) through which air, obtained by having a filter (17) remove moisture and oil content from air supplied from a compressor, is allowed to pass from the upstream to the downstream; a drain discharge valve (25) for opening the path between the compressor and the filter (17) to the atmosphere when the air pressure downstream of the check valve (19) becomes higher than a predetermined pressure; a regeneration control valve (21) for supplying air downstream of the check valve (19) to the filter (17), in a direction from the check valve (19) side to the drain discharge valve (25), by performing an operation of connecting a bypass flow path (20) to the check valve (19) in parallel therewith on the basis of supply of electricity; and a switching circuit (120) for operating the regeneration control valve (21), upon reception of the value of air pressure downstream of the check valve (19), by supplying electricity to the regeneration control valve (21) when the value of air pressure is in a predetermined range.
