Patent ID: 8403055

Claim:
A hydraulic coupler for communicating fluid between a first and a second member the coupler comprising: an axially compliant tubular; a first base connected to a first end of the tubular having a side in pressure communication with a region ambient to the second member; a bore extending through the first base; a second base connected to a second end of the tubular having a side for pressure communication with a passage formed in the second member; a bore extending through the second base; an elongated shaft coaxially disposed within the tubular; a first head on an end of the shaft that seats against the first base and defines a pressure seal between the bore in the first base and the region ambient to the second member, a second head on an end of the shaft opposite the first head that seats against the second base and defines a pressure seal between the bore in the second base and the passage formed in the second member; a male stab mounted on the first member having a surface that engages with the first base and circumscribes the first head, so that contacting the first base with male stab compresses the tubular and moves the first base relative to the first head, thereby breaching the pressure seal between the first head and bore in the first base; and a cavity on the surface of the male stab having a face that is set back, so that as the male stab compresses the tubular, the cavity face engages the first head to push the shaft and the second head thereby breaching the pressure seal between the second head and the second base.
