Abstract:
1. A fluid flow control valve for regulating the flow of fluid, the fluid flow control valve comprising: a housing having a generally spherical exterior portion sized to pivotally cooperate within a coupling oriented at an opening of a pressurized fluid duct, the housing having a central bore formed therethrough defining an inlet end and an outlet end, the housing having an annular shoulder spaced apart from the outlet end; a control member having a knob extending from the housing outlet end to be gripped and rotated manually, the control member including at least one axially extending clip extending from the knob into the housing outlet end and cooperating with the annular shoulder for fixing the control member for rotation relative to the housing; and a closure member having a first portion that is threadably engaged within one of the housing or the control member and the first portion is fixed for axial translation relative to the other of the housing or the control member, the closure member having a second portion that is adapted to sealingly engage with the inlet end of the housing central bore; wherein rotation of the control member in a first rotary direction causes the closure member second portion to extend axially from the inlet end due to the threadable engagement with one of the housing or the control member such that the closure member second portion becomes disengaged with the housing inlet end for permitting pressurized fluid to pass through the housing from the inlet end to the outlet end, and wherein rotation of the control member in a second rotary direction causes the closure member second portion to retract axially and engage the inlet end of the housing for limiting the flow of fluid therethrough.
