Unité (10) d'injection de réducteur, qui comprend un injecteur (12) de fluide, un élément (42) de tube, un filtre (204), un tube (52) de calibrage de filtre, un ensemble de soupape, une position du tube (52) de calibrage de filtre dans l'élément (42) de tube réglant une force antagoniste d'ouverture de l'ensemble de soupape et un élément (208) de réduction de volume. A fluid injector includes a fluid inlet, a fluid outlet, a fluid path from the fluid inlet to the fluid outlet; a tube; a filter disposed in the tube proximal to the fluid inlet; and a calibration filter tube disposed downstream of the filter. The calibration filter tube includes a first end portion adjacent the filter and an axial throughbore, the throughbore defining at least a portion of the fluid path through the fluid injector. An actuator unit is disposed within the fluid injector and engages a second end of the calibration filter tube. A valve assembly operatively couples to the actuator unit. A position of the calibration filter tube within the tube sets an opening force of the valve assembly. A cap member has a sidewall defining an inner space receiving the filter, and the sidewall contacts and attaches to the first end of the calibration filter tube.
