Fluid transfer tube for severe misalignment applications

摘要

A hydraulic system for a ram air turbine includes a hydraulic pump having a high pressure fluid outlet port, a housing, a pivot post arranged to pass through the housing and defining a mechanical pivot relative to the housing about an axis, a transfer tube positioned between the high pressure fluid outlet port of the hydraulic pump and a port in the housing for the high pressure fluid outlet path, and seal elements positioned at or near opposite ends of the transfer tube. A fluid inlet path and a high pressure fluid outlet path pass through the housing and the pivot post. The transfer tube has a crowned end.

1. A hydraulic system for a ram air turbine, the system comprising:
a hydraulic pump having a high pressure fluid outlet port; a housing; a pivot post arranged to pass through the housing and defining a mechanical pivot relative to the housing about an axis, wherein a fluid inlet path and a high pressure fluid outlet path pass through the housing and the pivot post; a transfer tube positioned between the high pressure fluid outlet port of the hydraulic pump and a port in the housing for the high pressure fluid outlet path, wherein the transfer tube has a crowned end, wherein at least a portion of the transfer tube is exposed to ambient air during deployment; and seal elements positioned at or near opposite ends of the transfer tube.
