摘要： A prosthetic joint includes: (a) a bone-implantable first member comprising a rigid material and including a body having an annular flange extending outward at a first end thereof, the first end of the body and the flange cooperatively defining a wear-resistant concave first contact surface having a protruding rim and a recessed central portion; and (b) a bone-implantable second member comprising a rigid material with a wear-resistant convex second contact surface; (c) where the first and second contact surfaces bear directly against each other so as to transfer axial and lateral loads from one of the members to the other, while allowing pivoting motion between the two members; (d) wherein the flange is shaped so as to deform elastically and permit the first contact surface to conform to the second contact surface when the joint is placed under a predetermined load.

摘要： An ultrahigh pressure pump includes a frame; a crankshaft having a journal; and at least one telescoping pump subassembly having inner and outer ends. The outer end is carried by the frame pivot so as to allow pivotal swinging movement of the pump subassembly, and the inner end is attached to the journal. The piston rod can reciprocate relative to the inner bore substantially free from side loads. The pump subassembly includes: an outer member including a cylinder defining an inner bore; and a inner member having a piston rod and a outer sleeve. The piston rod is received in the inner bore and the cylinder is received in the outer sleeve. First and second restraining elements are disposed at spaced-apart positions along the axis of the pump subassembly and are configured to oppose misalignment forces between the piston rod and the cylinder.
