Title:
COMBUSTION DRIVE TYPE RIVETING TOOL
Document Type and Number:
Japanese Patent JPS5721284
Kind Code:
A
Abstract:
Propane at a relatively low pressure and oxygen at a higher pressure are fed successively to combustion chamber 31 by way of duct 21, in which is closing valve 25, and duct 22 respectively, under the control of slide valve 13 which is coupled, by lateral arm 12 with an axially displaceable fastener guide tube 11 protruding at the muzzle of the tool and aligned with shaft 4 of piston 3. Upon pressing-in of the tube 11 when the tool is pressed against fastener-receiving material, recess 46 registers with nose 42a of trigger 42 to allow the latter to be actuated to supply ignition current to plug 37 and initiate combustion of the propane/oxygen mixture, thereby to drive the piston 3 and a fastener 48 previously loaded into the tube 11.
