Abstract
A modulator valve assembly (10) includes a valve seat (32) assembled as part of a housing (12), and the valve seat (32) defines inlet and outlet ports to allow fluid to flow between an inlet passage (28) and an outlet passage (30) along a fluid flow path. The modulator valve assembly (10) also includes a movable valve member (62) that is threaded to a rod (56) that extends through the valve seat (32), and as the rod (56) rotates, the movable valve member (62) moves axially along the rod (56). A pin (72) extends from the housing (12) to engage the movable valve member (62) to prevent the movable valve member (62) from rotating with the rod (56). The movable valve member (62) slides along the rod (56) into the fluid flow path and blocks the fluid from entering the housing (12).
