An oral irrigator handle has a handle housing with a swivel assembly for connection to a hose further connected to a fluid source. A tip for directing a focused stream of fluid is releasably connected to a first end of the handle. The swivel assembly is received within the housing and fluidly coupled to tip. The hose is connected to the swivel assembly and fluidly coupled to the tip via the swivel assembly. The swivel assembly prevents translation of rotational movement of the handle or the hose to the other.

A torque link assembly may comprise an upper torque link, a lower torque link, and a torque link pin. The upper torque link may define an upper hydraulic fluid channel. The lower torque link may define a lower hydraulic fluid channel. The torque link pin may fluidly couple the upper hydraulic fluid channel to the lower hydraulic fluid channel.

An apparatus and method for a generator for generating power having a rotary union between a rotor and a stator, the rotary union comprising a first fluid passage having a converging nozzle and located within the stator having a first inlet and a first outlet, a second fluid passage having a diverging nozzle and located within the rotor and having a second inlet and a second outlet, the second inlet is aligned with the first outlet and at least one gap located between the rotor and stator.

A fluid mating system includes a fitting connector, a mating connector and a planar slip system. The fitting connector includes an exterior mating surface and a first interior fluid passage that permits fluid flow along a first direction. The mating connector includes an interior surface that includes a tapered lead-in portion, an interior mating surface, and a second interior fluid passage. The second interior fluid passage permits fluid flow in the first direction. The first interior fluid passage and the second interior fluid passage include a single fluid path when the interior mating surface is engaged with the exterior mating surface. The planar slip system restricts movement of the mating connector in the first direction and allows at least partial free movement of the mating connector within a plane that is perpendicular to the first direction.

A multi-axis rotatable coupling element for a hose or pipe comprising a rotation assembly coupled between a female fitting and a male fitting. The female fitting has a first female threaded end connector for attachment to a hose or spigot, and a second end connector. The male fitting has a third male threaded end for attachment to a hose or spigot, and a fourth end connector. The rotation assembly consists of a first and second rotation member and a single continuous internal channel. The first and second rotation member are rotatable about a first and second axis of rotation, respectively, and have a first and second longitudinal bore for conveying fluid, respectively. The first and second axes of rotation may be different. The single continuous internal channel comprises at least the first and second longitudinal bore and conveys a fluid between the female fitting and the male fitting.

A flexible pipe joint (200) includes a body (210) having a pin-end member (230) telescopically fitted within a box-end member (220), the pin-end member (230) including an outer connection profile (235) and the box-end member (220) including a complementary inner connection profile (225), a bearing (240) including an outer bearing surface (244), wherein the bearing (240) is fitted within the body (210) such that at least a portion of an inner body surface (212) interfaces with at least a portion the outer bearing surface (244), and wherein the bearing (240) includes an inner bearing surface (243), and an extension pipe (270) including an outer extension pipe surface (289), wherein the extension pipe (270) is fitted within the bearing (240) such that at least a portion of the inner bearing surface (243) interfaces with at least a portion of the outer extension pipe surface (289).

A tubular scoop that may be utilized with various assemblies for sampling fluid in a pipeline. The scoop has a bend with a bend radius that is from two to four times the diameter of the scoop. The scoop defines a scoop face that is parallel to an axis of the tubular of the scoop. The scoop is mountable with a threaded connection that seals around the tubular. An additional seal with a compression nut allows orientation of the scoop within the pipeline whereupon the scoop orientation is fixed by tightening the compression nut.
