PROBLEM TO BE SOLVED: To perform injection work without needing to hold an injection device and an injection valve by hand. SOLUTION: The injection valve comprises a socket body installed in an injected body to allow communication between the inside and outside of the injected body and to receive a plug for leading out fluid in the injection device; a valve seat with a communicating hole formed at in the socket body to partition the socket body into an outer chamber for receiving the plug body, and an inner chamber communicating with the outer chamber via the communicating hole; a valve stem with an energizing means installed penetrating the communicating hole of the valve seat, to locate one end on the outer chamber side and the other end on the inner chamber side and to always energize the whole valve stem to the outside; and a valve element fixed to the other end of the valve stem to normally abut on the valve seat to close the communicating hole. When the plug body of the injection device is inserted in the outer chamber, one end of the valve stem is pressed inward to open the valve element. The socket body is constituted to detachably lock the inserted plug body. COPYRIGHT: (C)2007,JPO&INPIT
