PURPOSE:To provide a compressed air take-off device having no compressor, which is cheap, simple and miniaturized, by obtaining compressed air from a combustion chamber in an engine with the use of compression or combustion expansion. CONSTITUTION:Upon operation of an engine, when a compressed air take-off valve is opened by a valve opening lever 13, high pressure gas which is burnt and expanded is jetted from a compressed air blow-out port 15 after passing through a compressed air outlet port 10 opened to a combustion chamber 8 and a compressed air conduit 14. This is used as compressed gas for inserting a binding rope 20 into a binding rope inserting hole 24 in binder needle 23 through a binding rope supply conduit 21 in a reaping and binding machine, and so fourth. |
