Publication number: 20230340851Abstract: A remotely-operated fluid connection assembly to hold higher internal pressures in larger diameters. The assembly comprises a fluid connection adapter and a fluid connection housing assembly. When the adapter enters the housing assembly: (A) locking elements on the housing assembly constrict about the adapter; and (B) at least a first seal section on the adapter sealingly contacts a first seal bore on the housing assembly. Progressive engagement of a locking ring upon the locking elements urges the locking elements to tighten against the adapter. Internal pressure encourages adapter displacement, which then further tightens the adapter against the locking elements as now restrained by the locking ring. Internal pressure further encourages the first seal section on the adapter to expand radially to tighten the contact with the first seal bore in the housing assembly.Type: ApplicationFiled: June 29, 2023Publication date: October 26, 2023Inventors: Matthew E. Kibler, Kyle Scholl, Keith C. Johansen, Nicolas G. Snoke

Publication number: 20230272687Abstract: A remotely-operated fluid connection assembly to hold higher internal pressures in larger diameters. The assembly comprises a fluid connection adapter and a fluid connection housing assembly. When the adapter enters the housing assembly: (A) locking elements on the housing assembly constrict about the adapter; and (B) a first seal section on the adapter sealingly contacts a first seal bore on the housing assembly. Progressive engagement of a locking ring tightens the locking elements against the adapter. Internal pressure further tightens the adapter against the locking elements and the first seal section against the first seal bore. The fluid connection adapter also provides a release collar in adapter release embodiments. Extension of the locking ring away from the fluid connection housing during disengagement contacts the release collar and separates the fluid connection adapter from the fluid connection housing assembly.Type: ApplicationFiled: May 3, 2023Publication date: August 31, 2023Inventors: Matthew E.

Patent number: 11313195Abstract: A remotely-operated fluid connection assembly to hold higher internal pressures in larger diameters. The assembly comprises a fluid connection adapter and a fluid connection housing assembly. A first seal section on the housing assembly sealingly contacts a first seal bore on the adapter when the adapter enters the housing assembly. Engagement of an externally-disposed locking ring on locking element outer surfaces causes inner surfaces on the locking elements to retain the adapter to the housing assembly via a lock engagement surface. The first seal section is further disposed to expand radially such that when the first seal section expands radially, the first seal section further tightens sealing contact against the first seal bore. Adapter displacement relative to the housing assembly preferably further tightens the adapter against the locking elements as now restrained by the locking ring.Type: GrantFiled: April 29, 2021Date of Patent: April 26, 2022Assignee: FHE USA LLCInventors: Matthew E.

Publication number: 20200016611Abstract: A solids separator includes a housing having a fluid inlet, the fluid inlet oriented to induce helical flow of fluid entering the housing. A flow reversing device is disposed within the housing and is arranged to reverse a longitudinal direction of the helical flow within the housing. A fluid outlet is disposed at an upper end of the housing. The fluid outlet includes within its cross-section a radial center of the housing.Type: ApplicationFiled: October 2, 2018Publication date: January 16, 2020Inventors: Matthew Kibler, Kyle Scholl, Nicolas G.

Publication number: 20190301260Abstract: A fluid connection has a housing affixable to a fluid coupling and a seal bore in the interior. An adapter has a seal on an exterior engageable with the seal bore and a lock engagement surface, the adapter has a maximum outer diameter section. Locking elements are coupled to the housing by respective pivots, and each element has an inner and outer working surface on one side of the pivot and a contact surface on the other side of the pivot. The inner working surface has a taper opposed to the lock engagement surface. The contact surfaces and the maximum outer diameter section are such that the inner working surfaces contact the lock engagement surface. A lock ring is coupled to the housing by an actuator. When the actuator is extended the lock ring exposes the outer working surfaces, and when retracted the lock ring surrounds the outer working surfaces.Type: ApplicationFiled: July 17, 2018Publication date: October 3, 2019Inventors: Matthew Kibler, Kyle Scholl, Nicolas H.
