A gun having a gun body which includes a housing for component inlet and outlet passages and for a product flow control valve, which further includes a handle, a nozzle receiver assembly, and a trigger for rotating a spool valve between open, closed, and intermediate positions, and wherein means are provided for controlling the proportion and flow rates of the components within the flowing passages, and to facilitate insertion, locking, and ejection of the nozzle within the gun body.

A gun assembly for directing at least two individual streams of separate reactive liquid components toward an associated mixing and dispensing nozzle assembly, said components being adapted, upon reaction with each other, to produce a thermosetting resinous material, said gun assembly comprising, in combination, a gun body including means therein defining plural spaced apart liquid inlet passages, and plural, spaced apart liquid outlet passages positioned to receive liquid from said liquid inlet passages, said body also having a cylindrical sidewall defining a spool-receiving bore extending transversely of the axes of said inlet and outlet passages, means including an end wall and sidewalls formed in said body for defining an opening in said gun body for receiving a nozzle assembly in fluid-tight relation to said gun body interior, a gun handle extending downwardly from said gun body in position of use, a flow control valve spool rotatably received within said spool-receiving bore in fluid tight relation, passages extending through said valve spool transversely of the rotational axis thereof, said passages being spaced from each other and constructed and arranged so that, upon valve spool rotation, said passages become, respectively, fully registered, partially registered, and finally completely out of registry with said inlet and outlet passages in said housing, said valve spool further including trigger mounting means on each end thereof, each of said outlet passages terminating at said end wall of said nozzle-receiving opening, whereby said components may be mixed within the end of a nozzle positioned within said nozzle-receiving opening in said gun body, a trigger unit having one end portion thereof actuable by the fingers of a user and having its other end bifurcated so as to form a yoke- having opposed, spaced apart end portions, each of said yoke end portions being affixed to one of said trigger mounting means on said valve spool ends, said yoke end portions also lying closely adjacent said gun body and being spaced apart therefrom only by a working clearance so as to prevent transverse movement of said valve spool within said gun body, and means normally biasing said trigger to a position wherein said valve spool passages are out of registry with said liquid inlet and outlet passages.
