Abstract:
1. A pressure actuated resilient seal carrier assembly comprising: a. a one-piece seal carrier composed of a metal, the seal carrier comprising a body with an inner projection and an outer projection on a first side, wherein the projections are integral with the body and positioned on opposite sides of the first side of the body to one another, wherein a cavity is formed between the projections and the body, the cavity having a first sidewall, a second sidewall and a bottom surface, wherein an inner groove is formed in the inner projection, and wherein an outer groove is formed in the outer projection; b. a flexible non-metallic first seal positioned in the inner groove; c. a flexible non-metallic second seal positioned in the outer groove; and d. a metal spacer disposed in the cavity, which does not substantially fill the cavity wherein the spacer maintains spaces between the inner groove and the outer groove and bears axial loads due to a pressure end load transmitted through the spacer while being capable of maintaining an axial separation with adjacent components, thereby forming a resilient seal carrier assembly providing no extrusion gaps with the non-metallic seals when activated by pressure, wherein the seals further comprise a spring, wherein a cavity space is formed between the spacer and the first sidewall of the cavity so that the spacer does not contact the first sidewall; e. said body having a second side opposite the first side, the second side having a second cavity formed therein.
