Patent ID: 7247006

Claim:
A sealing assembly for an ultrahigh-pressure fluid system having a cylinder, the sealing assembly comprising: a seal having a bore through which a plunger may reciprocate; a bearing positioned adjacent the seal and having a bore through which the plunger may reciprocate; a seal carrier circumferentially surrounding the bearing and being subjected to a compressive force at least when in operation; and an inner surface of the bore of the bearing being in substantially uniform circumferential contact with an outer surface of the plunger when the assembly is subjected to loading during assembly, wherein the seal carrier is configured to contact the cylinder to form a static seal along a tangential sealing area, and the seal includes a first end contiguous a proximal end of the bearing with respect to the seal, the bearing includes a distal end with respect to the seal, opposite the proximal end of the bearing, and the first end of the seal is axially spaced from a center point of the tangential sealing area in a direction pointing from the distal end of the bearing toward the seal, when the sealing assembly is installed in the ultrahigh-pressure fluid system.
