Abstract

A gas combustion-type impact tool, where a flammable gas is fed to a combustion chamber (10) from a gas container (20) filled with the flammable gas to produce a mixture gas composed of air and a combustion gas in the combustion chamber (10) and a high-pressure combustion gas is produced in the combustion chamber (10) by combustion of the mixture gas in the combustion chamber (10) by conducting electricity to an igniter (25). A temperature detector (33) for detecting an ambient temperature of the gas container (20) is provided in the tool. A temperature detected by the temperature detector (33) is compared with a pre-set temperature and electricity to the igniter (25) is shut off when the temperature near the gas container (20) is higher than a set temperature.

Description

L26743〇^__________. V. INSTRUCTION DESCRIPTION (1) Technical Field of the Invention The present invention relates to a gas combustion type impact tool in which a combustible gas and air are mixed in a combustion chamber formed above a striking cylinder= The gas is combined to generate a spark in the combustion chamber, and the mixed gas is burned, and the combustion gas generated in the combustion chamber is used to drive the striking piston accommodated in the name. L previously used in the drive to produce indoor ignition in the use of combustion and into the operation of the cylinder is flammable to make the mouth of the 21-shaped combustion chamber to produce the technology] gas burning machine, flammable burner production room Produce the piston, this hit. In this example, it is known that a combustion gas is injected into a combustion chamber in which the combustion gas is injected into the combustion chamber in the combustion chamber in which the combustion gas is injected into the combustion chamber. a mixed gas with air, in the combustion chamber, a spark discharge b, the ignition gas is ignited to cause combustion, and the pressure of the combustion gas is applied to the driving striking piston which is contained in the striking cylinder and is shocked in the cylinder. , such as: ί: face: the limit of the power supply to the steel plate or concrete power or compressed air: the burning gas drives the nailing machine, and the inside of the outer casing is installed in the same casing to install the filling body. To make the flammability of the gas container filled in the chamber parallel to the blow cylinder substantially parallel to the combustion chamber: In addition, A uses the nozzle to: rotate the flammable gas and the (7) in-gas fuel ratio in the combustion chamber to form a rotation =

INSTRUCTIONS (2) The gas container is filled with liquefied gas such as diced gas, and the pressure of the gasified gas is used to supply the 篮 宕 宕 宕 纨 纨 纨 纨 纨 f f f “ “ “ “ “ “ “ The air is agitated to produce a mixed air-fuel ratio of the air-fuel ratio. (In addition, it is disposed in the combustion chamber to be in the combustion chamber by means of a combustion chamber.) The mixed gas point igniter is generated. The igniter is formed by a spark plug or the like, and after the voltage of the pool is boosted to a high voltage, the spark is turned on by the high voltage. The electric gate generates electricity and the electrician operates on the rear side and The trigger formed by the base of 3, the high voltage is applied to the handle chamber of the point body: a spark is generated. Therefore, the inside of the combustion chamber is energized and burned in the nail machine. The emulsion is ignited and driven, such as the above-mentioned gas-fired striker. If the tool is used under the sun, it will be placed in the trunk of the hot sun in the sun. It is in the trunk of the car under the sun in the summer, and it is in the middle of the work, or it is kept in the parking. Therefore, the whole tool becomes high temperature. Time , the whole work becomes the high-temperature device of the high-temperature device, and the gas content in the gas container is installed. When the pressure in the gas container becomes high, the ink force of the gas is increased. Excessive flammable gas, there is no possibility of generating a gas that can be burned in the room. Therefore, it is impossible to ignite by the point of air-fuel ratio, and there is a burning order in the unscheduled scale. The gas mixture becomes high due to the pressure of the gas, and the flammable gas is caused by the danger of the gas. In addition, the path leaks and remains in the flammable inside of the casing, and the gas is ignited by the igniter.

Description of invention (3) Ignition, accidents may occur [invention] The subject of the price is to provide a gas-fired impact tool, crying 1 S filling the gas of flammable gas When the temperature of the container itself or the gas chamber is higher than a predetermined set temperature value, the energization of the voltage for discharging the ignition device is cut off, so that the discharge in the combustion chamber is not performed, and the filling is performed. In the combustion chamber fire device, the piston impact tool detector is driven by the combustion chamber, and the control temperature value is used to break the point by the detector, and the set temperature of the device is determined by the above-mentioned flammability gas. Electricity, the ignition of the combustion, so that the characteristics of the rushing 'the characteristics of the temperature device than when the gas fire device is in control and the control value of the temperature, when the subject, the gas of the burning gas burning Indoor gas burning is to set the detector to the temperature of the container. Setting a detection and detecting device, measuring the temperature, the mixing pressure of the body and the air in the body container of the invention is used to drive the detection gas. The gas around the detector is contained in a gas mixed gas point for the gas. The detection degree of the temperature of the piston body container is higher than the gas fire of the combustion type internal body device, and the striking cylinder is used, and the detected temperature value of the ambient temperature of the gas container is controlled by the temperature and the constant temperature. When the control device compares the detected value to a higher temperature than the set temperature, the impact tool is supplied to the igniting gas, and the gas is burned by the point-to-point combustion, and the preset temperature is set. When the temperature is detected, the temperature is controlled to ignite the temperature value and the ignition will be ignited.
