Abstract:
Apparatus for regulating the volume of fluid flowing received from a fluid source, comprising:an inner cylinder, having a side wall and a hollow interior, said inner cylinder including a first inlet aperture at one axial end thereof for receiving the fluid into the hollow interior and including a first outlet aperture in said side wall for discharging the fluid, said inner cylinder being adapted for coaxial mounting within an outer cylinder; anda housing, having an outer cylinder, said outer cylinder including a side wall having a second outlet aperture for discharging fluid and a hollow interior adapted to receive said inner cylinder therein in a nested relationship which permits relative rotation of said cylinders about a common longitudinal axis to selectably provide maximum registration and, alternately, minimum registration of said first and said second outlet apertures, said outer cylinder further including at an axial end thereof a second inlet aperture adapted for fluid communication with the fluid source and with said first inlet aperture of said nested inner cylinder, whereby selectable rotation of said cylinders regulates the fluid volume flowing from said second inlet aperture to said second outlet aperture, from a maximum flow to a minimum flow, in response to maximum registration and minimum registration, respectively, of said first and said second outlet apertures.
