  • the inward curved part of the sealing member is made of an elastic material and curved inward with respect to the lower end periphery of the cartridge filled with the viscous agent, and due to the above structure, the more the pressure in the gas chamber is increased, the more the inward curved is Part tightly applied to the inside of the lower end circumference of the filled cartridge. Thus, the sealing property of the sealing part against air is further improved.
  • the device according to the invention uses a safety valve for discharging the compressed gas from the channel or the gas chamber.
  • the safety valve is arranged to be closed at all times when the viscous cartridge is inserted into the gas chamber and open at all times when the viscous cartridge is removed from the gas chamber.
  • this device has a safety valve for releasing the compressed gas within a compressed gas chamber.
  • This safety valve is actuated at the time when the cartridge filled with viscous agent is removed from the compressed gas chamber. Accordingly, the cartridge filled with the viscous agent can be safely removed without any special gas release operation.
  • an elastic tube configured to allow the viscous agent to pass therethrough is inserted within the injection control valve so that the elastic tube is opened and closed in accordance with the opening and closing operations of the injection control valve.
  • the injection control valve seeks to clog with the viscous agent.
  • this clogging is solved by merely changing the elastic tube because the viscous agent is stuck within the elastic tube according to the invention. Simple handling of the injection control valve is thus achieved.
  • an inner wall surface of the end periphery of the fitting hole of the elastic pipe is formed with a circumferential groove.
  • the circumferential groove is V-shaped, a smooth, tapered portion is formed at one end of the circumferential groove. Accordingly, the close contact between the elastic tube and the cartridge filled with the viscous agent is further improved, whereby an even further improved sealing effect is obtained.
  • the elastic tube is covered with a heat shrinkable sheet which has a rigid property, from the front end thereof to the injection control valve. Accordingly, despite the fact that the elastic tube is made of a soft, elastic material, the shape of its front end is always kept constant. As a result, easy positioning for applying the viscous agent is obtained every time the viscous agent is filled.
  • the shape of the front end portion of the elastic tube can be appropriately changed in accordance with its purposes.
  • the heat-shrinking film consists of a cylindrical part, it is tightly fitted to the elastic tube by heating. An effortless fit of the heat-shrinking film is thus achieved.
  • a valve housing of the injection control valve is fitted to the injection port of the viscous-filled cartridge through an elastic seal member, then even if the shape of the injection port of the viscous-filled cartridge is not constant, e.g. the outer peripheral surface of the injection port is threaded, or even if the injection port is deformed, it is brought into close contact with the injection control valve.
  • a pressure reducing device is provided between the compressed gas source and the gas chamber, and the pressure decrease rate of the pressure reducing device is made adjustable, then a viscous agent having an arbitrary viscosity can be effectively injected.
  • a device for injecting a viscous agent as claimed in claim 1 comprising a base body and a gas chamber which has an opening and a receiving seat and is arranged on a rear portion of the base body while the opening is facing forward, wherein the receiving seat is provided on the front portion of the base portion, the receiving seat is provided with an injection control valve, a cartridge filled with viscous agent is inserted into the opening of the gas chamber at its rear portion, an injection nozzle is connected at its front portion to the injection control valve is when a sealing member is provided on the periphery of the opening of the gas chamber, the viscous-filled cartridge is slidably movable while having an airtight state of the viscous-filled cartridge with respect to the sealing member, and at the same time the receiving seat around an axis towards the rear and the front of the base section is pivotable with respect to the base section, the receiving seat is further moved to either the left or the right from its normal position (the position for receiving the cartridge filled with the viscous agent) in order to insert the rear section
  • the receiving seat is not required to move by turning an adjustment screw after the rear portion of the viscous-filled cartridge is inserted into the opening of the gas chamber. A simple construction and an easy assembly of the cartridge filled with viscous agent is thus achieved.
