Abstract:
An example valve includes: (i) a valve body defining a first longitudinal bore therein and including a first inlet, a second inlet, and an outlet; (ii) a cage disposed in the first longitudinal bore coaxial with the valve body, where the cage defines a second longitudinal bore therein; (iii) a pin mounted and extending longitudinally within the second longitudinal bore at an end of the cage adjacent to the first inlet; and (iv) a spool shiftably mounted within the second longitudinal bore and configured to move axially therein to shift between a first position and a second position. The spool includes a blind hole formed at an end thereof facing the pin and coaxial therewith, such that as the spool shifts from the second position to the first position, a portion of the pin is received within the blind hole of the spool.
