Abstract:
1. An injector for injecting a reagent, comprising: a housing; an electromagnet positioned within the housing; and an axially translatable valve member positioned within the housing, the valve member being translated from a seated position to an unseated position in response to energizing the electromagnet, the valve member including a hollow tube having a substantially constant wall thickness, a ball and a pintle head, the tube including a curled end having a reduced diameter sized to allow the ball to partially extend beyond the tube end but not pass through the tube, the tube including an inwardly extending detent restricting the ball from movement within the tube, the pintle head being fixed to the tube and positioned proximate the electromagnet, wherein the tube includes another inwardly extending detent circumferentially spaced apart from the detent.
