Abstract

The high pressure seal assembly is for sealing an interface between two relatively moving members such as in a high pressure piston and housing assembly. The first member having a first sliding seal surface to engage the seal assembly and movable relative to the seal assembly, the second member having a second stationary seal surface to engage the assembly and being stationary with respect to the seal assembly. The seal assembly having a forward high pressure side and a rear low pressure side. The seal assembly comprising: (a) a first rear substantially rigid backup ring means fixedly mounted to the second member, (b) a second relatively high yield strength seal ring means positioned between the first and second surfaces and forward of the back-up ring means, the second ring means fitting closely against the first surface.
