ABSTRACT:
A fluid flow control valve according to the invention includes a base, a valve member, a trigger member and attachment means for attaching the trigger member to the valve member. The base includes a generally horizontal throat and a flange having an upwardly facing surface. The valve member has a stem, a flow level establishing member associated with the stem and biasing means for biasing the stem in a direction opposite to that in which the throat extends. The trigger member includes a pin configured to rotate against an inner end portion of the throat, a flange having a downwardly facing surface and an actuating portion. The biasing means acts in a direction through the attachment means to pull the actuating portion downwardly such that the flanges engage in order to retain the pin in the throat. In this manner, the valve may be assembled without the use of fasteners.
