Ultrahigh-pressure check valve |
摘要 |
A check valve for use in a high-pressure pump is provided with a check valve seat having a frustoconical end region that engages a tapered surface provided on an outlet adaptor. By providing a conical interface between the check valve seat and the outlet adaptor, a compressive stress is placed on the valve seat, thereby dramatically increasing the fatigue life of the check valve.
