Title:
CARTRIDGE TYPE GREASE GUN
Document Type and Number:
Japanese Patent JP3403547
Kind Code:
B2
Abstract:
PURPOSE: To supply quantities of grease in a short time, by interposing a sealing body, for sealing the flow of gas, between a gas exhaust nozzle and a gas inflow path, and providing a boring device, for boring the sealing body to open to communicate the gas exhaust nozzle and the gas inflow path, on a gas bomb.
CONSTITUTION: A gas bomb 16 filled with a high-pressure gas is detachably fitted to an end cover 6 via a screwed type connecting member 17. A boring device 26, for boring an enclosing packing 23 to open to communicate a gas exhaust nozzle 19 and a gas communicating path 22, is provided on the bomb 16. An operation part 29 is struck by a hammer, etc., to place a needle rod 27 into the bomb 16. Consequently, the tip of the rod 27 breaks the packing 23 to form an opening part on the packing 23. As a result, the nozzle 19 of the bomb 16 and the communicating path 22 of the connecting member 17 are opened to be communicated, and the high-pressure gas in the bomb 16 is blown out from the nozzle 19 to be flowed in a gas inflow path 21 to be flowed in a space 20 in an oil cylinder 3.
