PROBLEM TO BE SOLVED: To provide a hoseless gun capable of readily increasing the pressure of a working gas, and repeatedly using the initially filled working gas when repeatedly conducting the refilling of viscous fluid. SOLUTION: At the initial state of a hoseless gun 1, an auxiliary tank 5 is filled with a working gas A from a gas inlet 51, and a rear end side cylinder chamber 32, which is formed when a piston 3 is pushed out to the front end side of a cylinder tank 2, is filled with a working gas A as well. When filling a viscous fluid L from a fluid inlet 22, a front end side cylinder chamber 31 is filled with the viscous fluid L while the working gas A, which is filled in the auxiliary tank 5 and the rear end side cylinder chamber 32, is compressed, by pushing out the piston 3 to the rear end side of the cylinder tank 2 by means of the viscous fluid L. The viscous fluid L is made to flow from a nozzle 4 by pushing out the piston 3 by means of the compressed working air A by operating an operation valve 6. COPYRIGHT: (C)2013,JPO&INPIT |
