ABSTRACT:
A main body is provided having a fluid passage extending therethrough including inlet and outlet ends. The body further defines a branch passage having an outlet end portion opening outwardly of the body and an inlet end portion opening into an intermediate portion of the main fluid passage. The intermediate portion of the main fluid passage includes structure defining a valve seat therein and a valve body is mounted in the inlet end portion of the branch passage for adjustable positioning therealong and includes a main valve portion opposing the seat and operable to variably throttle the main flow passage upon shifting of the main valve portion toward and away from the seat. The valve body includes a flow passage formed therein having an inlet end opening through the main valve portion and communicating with the main fluid passage intermediate portion and an outlet end communicating with the outlet end portion of the branch passage. A valve member is shiftably supported from the valve body and is operable to variably throttle and close the flow passage. Shifting of the valve body main valve portion toward and away from the valve seat of the intermediate portion of the main passage serves not only to variably throttle the main fluid passage but to also throttle the main fluid passage upstream from the flow passage and thereby the maximum fluid flow which may pass through the flow passage.
