Rotating Control Device with Latch Biased Toward Engagement

A rotating control device, comprising:

• an outer housing;
• an assembly having at least one of a bearing and a seal in a passage extending through the outer housing;
• and
• a latch in the outer housing, the latch including at least one engagement member which releasably secures the assembly relative to the outer housing, and which is biased outwardly by the assembly when the assembly is installed in the outer housing, and wherein the engagement member is biased toward an engaged position without use of fluid pressure.

A method of releasably latching a bearing assembly relative to an outer housing of a rotating control device, the method comprising:

• applying fluid pressure to an actuator of a latch of the rotating control device;
• then positioning the bearing assembly in the outer housing at an operative position;
• and
• then reducing the fluid pressure, thereby allowing a biasing device to displace at least one engagement member of the latch into engagement with a profile formed on the bearing assembly.
