Abstract
A valve for controlling the rate of fluid flow therethrough by rotating a rotor about a spindle having an inlet bore in communication with an eccentrically oriented o-ring set into an eccentrically oriented slot formed in the rotor. The perimeter of the eccentric slot is modified to provide customized unique fluid flow response curves.
Claims20
A valve comprising:
- a spindle having an inlet bore extending longitudinally from a top end of the rotor with a radial inlet aperture;
- a rotor having a first bore dimensioned to receive the spindle and a second bore in eccentric orientation to the first bore;
- an o-ring dimensioned to fit within the second bore of the rotor;
- a rotor gear press fitted onto a bottom surface of the rotor;
- a mounting plate having a top surface to which the rotor gear is affixed;
- a drive gear in synchronous orientation with the rotor gear;
- a motor attached to a bottom surface of the mounting plate and having a shaft to which the drive gear is attached.
