Claim Text:
1. A continuous flow regulator for regulation of the flow of coolant through the heating coil of a vehicle heating system, the continuous flow regulator comprising a body having an upstream end, a downstream end, an internal channel, and a cylindrical portion of the internal channel defined by a cylindrical wall, the body being configured to be coupled in-line with the flow of coolant so that coolant flows through the internal channel from the upstream end of the body to the downstream end of the body, a ball valve assembly disposed within the internal channel and including a ball yieldably biased to a first position adjacent an upstream end of the cylindrical portion, the ball being movable against the bias to a second position adjacent a downstream end of the cylindrical portion, and structures projecting from the cylindrical wall into the cylindrical portion of the internal channel, the structures being configured to progressively restrict flow through the cylindrical portion of the internal channel along a length defined by the first position and the second position.
