A gun assembly for directing at least two individual streams of separate reactive fluid 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 a component passage and flow control valve housing having means therein defining plural spaced apart inlet passages, plural, spaced apart outlet passages positioned to receive fluid from said inlet passages, a cylindrical sidewall defining a spool-receiving bore extending transversely of the axes of said inlet and outlet passages, means on said gun body defining a nozzle receiver assembly, means for locating a combination nozzle and latch ejector element, 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 spool transversely of the rotational axis thereof, said passages being spaced from each other and constructed and arranged to that, upon 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 spool further including trigger mounting means on each end thereof, portions of each of said gun body inlet passages further including a metering jet with a discharge orifice therein of a predetermined size, each of said jets being formed separately from said body and each including an at least partly cylindrical, spool-engaging surface, said outlet passages having means therein for engaging the inlet openings forming a part of said associated mixing and dispensing nozzle assembly in fluid tight relation, a combination nozzle latch and ejector element positioned by said locating means for pivotal movement between positions of nozzle latching and ejection, a trigger unit having a portion for actuation by the fingers of a user forming one end thereof 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 trigger 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 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 inlet and outlet passages, said outlet passages being constructed and arranged so as to permit said inlet openings on said nozzle to lie closely adjacent said spool assembly when said nozzle is received in position of use in said gun body.
