Abstract

See full text

A sealing system for a high pressure pump, in which the pump includes a vessel defining a vessel bore and having an end portion, the vessel bore having a first engagement face and defining a central longitudinal axis, and in which the pump further includes a plunger cooperative with the vessel to increase the pressure of a fluid within the bore, includes a seal member at least partially received within the bore and defining a second engagement face. The sealing system further includes a retaining member in operative contact with the seal member to mate the first engagement face with the second engagement face to inhibit fluid leakage from the bore. The first engagement face includes a first contacting surface having a non-linear cross-section. The second engagement face includes a second contacting surface having a non-linear cross-section in contact with the first contacting surface.
