First circumferential grooves (first compressed air supply grooves, first pressure oil supply grooves, and a first coolant supply groove) formed on a first sliding surface, and second circumferential grooves (second compressed air supply grooves, second pressure oil supply grooves, and a second coolant supply groove) formed on a second sliding surface are formed in a rotary joint to be opposite to each other when seen from a radial direction of the rotary joint. In one pair of the opposite first circumferential groove and second circumferential groove, a type and a use of a fluid flowing in the first circumferential groove is the same as a type and a use of a fluid flowing in the second circumferential groove.

The disclosure describes a rotary device that includes a housing, a rotating machine component, a rotating member associated with the rotating machine component, a non-rotating member disposed within the housing adjacent the rotating member, and a sensor array disposed in the housing. The sensor array includes a plurality of sensing elements that are integrated with a control device and a wireless communication device. The wireless communication device is configured to communicate with a central control that is remotely located relative to the housing using electromagnetic waves.

A device for distributing fluid media for a rotary machine, in particular a filling machine, including: a rotary distributor having a non-rotatably designed first assembly and a second assembly designed to be rotatable about a machine's axis of rotation, wherein the first assembly comprises one or several supply points for at least one fluid medium, and one or several supply lines for the at least one fluid medium connected with the supply point or supply points, wherein at least one supply line includes two or more lying swivel joints whose axes of rotation are arranged essentially in parallel to the machine's axis of rotation.

A rotary union for use along an incompressible fluid path between a rotating machine component and a non-rotating machine component includes a non-rotating seal carrier including a non-rotating seal element, which together with the non-rotating seal carrier define a net hydraulic surface on an internal side and a net pneumatic surface on an external side. Contact of an incompressible fluid under pressure with the net hydraulic surface creates a closing force, and contact of a compressible fluid under pressure with the net pneumatic surface creates an opening force.

A rotary device includes a housing, a rotating machine component, a rotating member associated with the rotating machine component, a non-rotating member disposed within the housing adjacent the rotating member, and a sensor array disposed in the housing. The sensor array includes a plurality of sensing elements that are integrated with a control device and a wireless communication device.

For a simply constructed pivot and swivel joint securing a sealing of the control element for the connection of a support arm to a control element, it is provided that the pivot and swivel joint (3) is implemented having a rotary sleeve (10) including an axially continuous recess (41) and having a swivel sleeve (11) connected thereto via a swivel axis (S) including an axially continuous recess (42), which is swivelable relative to the rotary sleeve (10) about the swivel axis (S), a rotary axis (D) being configured at the axial end of the rotary sleeve (10) facing away from the swivel axis (S), and a sealing hose (30) being disposed between the rotary sleeve (10) and the swivel sleeve (11), which by a first axial end sealingly abuts at the recess (41) of the rotary sleeve (10) and by the opposite second axial end is sealingly disposed at the axial end of the swivel sleeve (11).

A swivel joint device for limiting kinking of a vacuum hose includes a first connector and a second connector, which attach to respective ends of a first section and a second section of a vacuum hose, respectively. The second connector is complementary to the first connector and thus is selectively engageable to the first connector. The second connector and the first connector join the second section and the first section of the vacuum hose. At least one of the second connector and the first connector comprises a bearing so that the second section and the first section of the vacuum hose are rotatable relative to each other. The second connector and the first connector thus limit kinking of the vacuum hose.

A faucet having a base, an articulable spout, and a valve operable in an open position and a closed position to control the flow of water to the outlet. The base is configured to mount to a support. The spout includes an outlet for dispensing water and a plurality of segments operatively coupled together sequentially, with a first segment of the plurality of segments rotatably coupled to the base. The plurality of segments are rotatable relative to one another and to the base to move the outlet between a first position, in which the valve is in the closed position, and a second position, in which the valve is in the open position.

In one aspect, a method provides a reciprocating bolt by a bolt assembly having a bolt assembly body, a cap affixed to the bolt assembly body, and a base affixed to the bolt assembly body opposite the cap. The method includes biasing a bolt carrier in the bolt assembly body in a retracted position relative to the bolt assembly, resulting in a center portion of a diaphragm disposed between the cap and the bolt assembly body being deflected toward the cap. The method also includes applying an actuation force to the bolt carrier so as to move the bolt carrier from the retracted position to an extended position relative to the bolt assembly by oppositely deflecting the center portion of the diaphragm toward the base, and discontinuing the applying of the actuation force while the bolt carrier is in the extended position.

A connector assembly for connection to a preconditioned air port on an aircraft that includes a rotatable coupling, a retractable latch, and a protective cage. The rotatable coupling has an upper coupling section with a circumferential ring on the exterior surface rotatably connected to a flanged surface on a lower coupling section. The lower coupling section includes a lower and adapted to be connected to the air duct. The retractable latch is actuated by rotation of the protective cage relative to the upper coupling section. The retractable latch is attached to the exterior of the upper coupling section and has a latching end and a pin on the other end. The protective cage has two or more circumferential slots and a guide slot on the interior surface. When the rotatable coupling is installed in the protective cage, the pin is inserted in the guide slot and the ring and flange are slidably inserted in the circumferential slots between an open position, wherein the retractable latch is disengaged, and a closed position, in which the retractable latch is engaged with the preconditioned air port. The protective cage surrounds the notable coupling and includes at least a first and second protective bumper at opposite ends of the protective cage. The protective cage extends over the duct connection to surround and protect the connection from coming in contact with the ground.
