Claims

[Scope of utility model registration request]

(1) In an injection valve in which a valve body that is opened by pressure of a valve stem is screwed into a valve seat portion through a seal portion, the seal portion protrudes from the valve body side and is connected to the valve seat side by metal. A metal seal protrusion made of a metal that contacts and seals and has a coefficient of thermal expansion similar to that of the metal constituting the valve seat, and a metal seal protrusion that is held by the metal seal protrusion and is screwed into the valve seat side. An injection valve consisting of an O-ring made of a heat-resistant member and in contact with the O-ring.

(2) The injection valve according to claim 1 or 2, wherein the metal seal member has a deformable piece protruding from the base.

(3) The injection valve according to any one of claims 1 to 3, wherein the metal seal member is formed by fitting the 01J ring onto the outer peripheral surface of the deformable piece.
