Abstract:
1. An inline liquid flow control valve comprising: an intake fitting member including a top portion and a bottom portion, the bottom portion including a bottom portion threaded section and a liquid flow section having a plurality of apertures; an outlet fitting member including a top portion having a plurality of apertures, the top portion including a top portion threaded section contactingly engaging the bottom portion threaded section of the intake fitting member; a piston disposed inside the intake fitting member, the piston having a primary face with a primary face aperture and a bottom portion with a plurality of bottom portion apertures; a compression member having a top portion engaging the bottom portion of the piston and a bottom portion of an interior channel in the top portion of the outlet fitting member; an annular sleeve disposed about the intake fitting member and the outlet fitting member; and a liquid flow chamber defined by the plurality of apertures in the intake fitting member, bottom portion apertures in the piston and the plurality of apertures in the outlet fitting member such that a flow rate of liquid through the liquid flow chamber is inlinely adjustable through the positioning of plurality of apertures in the intake fitting member relative to the bottom portion aperture in the piston and the flow rate of the liquid is maintained at a constant flow rate based on the compression member providing a compressive force against the piston.
