Abstract
Systems and methods include providing an annular seal stack for an assembly. The seal stack assembly is disposed between a probe and a housing of the assembly and configured to provide a radial seal between the probe and the housing. The seal stack assembly includes a first metallic seal, a second metallic seal, and a wiper assembly disposed between the first metallic seal and the second metallic seal. The wiper assembly includes a first wiper housing component having a tapered inner surface, a second wiper housing component having a tapered inner surface opposite the tapered inner surface of the first wiper housing component, and a wiper disposed between the first wiper housing component and the second wiper housing component.
Claims18
A wiper assembly, comprising:
- a first wiper housing component having a tapered inner surface;
- a second wiper housing component having a tapered inner surface opposite the tapered inner surface of the first wiper housing component;
- and
- a wiper disposed between the first wiper housing component and the second wiper housing component, wherein the first wiper housing component comprises a recess, and wherein the second wiper housing component comprises an elongated portion that is at least partially received by the recess of the first wiper housing component to allow translation of the first wiper housing component with respect to the second wiper housing component.
A seal stack assembly, comprising:
- a first metallic seal;
- a second metallic seal;
- and
- a wiper assembly disposed between the first metallic seal and the second metallic seal, the wiper assembly comprising:
- a first wiper housing component having a tapered inner surface;
- a second wiper housing component having a tapered inner surface opposite the tapered inner surface of the first wiper housing component;
- and
- a wiper disposed between the first wiper housing component and the second wiper housing component, wherein the first wiper housing component comprises a recess, and wherein the second wiper housing component comprises an elongated portion that is at least partially received by the recess of the first wiper housing component to allow translation of the first wiper housing component with respect to the second wiper housing component.
An assembly, comprising:
- a probe;
- a housing disposed annularly about the probe;
- and
- a seal stack assembly disposed between the probe and the housing and configured to provide a seal between the probe and the housing, the seal stack assembly comprising:
- a first metallic seal;
- a second metallic seal;
- and
- a wiper assembly disposed between the first metallic seal and the second metallic seal, the wiper assembly comprising:
- a first wiper housing component having a tapered inner surface;
- a second wiper housing component having a tapered inner surface opposite the tapered inner surface of the first wiper housing component;
- and
- a wiper disposed between the first wiper housing component and the second wiper housing component, wherein the first wiper housing component comprises a recess, and wherein the second wiper housing component comprises an elongated portion that is at least partially received by the recess of the first wiper housing component to allow translation of the first wiper housing component with respect to the second wiper housing component.
