20090032564 | Gas combustion type striking tool - A front portion of a feed cylinder of a feed piston-cylinder mechanism is communicated with a combustion chamber, and a rear portion of the feed cylinder is sealed. A check valve and a spring which constantly biases a feed piston toward a nail feed direction in the forward direction are provided. An opening valve communicating with the rear portion of the feed cylinder is provided. The opening valve is opened after or just before a completion of a returning operation of a striking piston. | 02-05-2009 |
