A watering nozzle including a handle configured to be grasped by a user, an inlet connector including a flange rigidly coupled to the handle, and an inlet engagement feature, a swivel coupling including a garden hose thread and a swivel shoulder adjacent a swivel opening arranged concentrically about a central axis, the swivel coupling rotatable relative to the handle about the central axis, and an insert shank including a swivel seal in sealed contact with the swivel coupling, a first shank shoulder in contact with the swivel shoulder, and a shank engagement feature in rigid engagement with the inlet engagement feature.

A faucet includes a base configured to attach to a support, an outlet for dispensing a fluid, an articulable spout including a plurality of segments operatively coupled together sequentially between the base and the outlet and configured to rotate relative to one another to transition the articulable spout between a first position and a second position, and an actuator operatively coupled to at least two segments of the plurality of segments and configured to rotate the at least two segments in opposite rotational directions.

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 connecting pipe has a connecting pipe portion having, at the opposite ends thereof, connection opening end portions. The connecting pipe has a bendable portion provided between the opposite ends of the connecting pipe portion to allow the connecting pipe portion to be bent relative to the longitudinal axis of the connecting pipe portion. The connecting pipe further has rigid portions extending from the bendable portion to the connection opening end portions, respectively. The rigid portions have a higher rigidity than the bendable portion. Bending the connecting pipe portion at the bendable portion allows the connection opening end portions at the opposite ends to be fitted to associated pipe end portions, respectively. The connecting pipe portion has an elastic restoring force to maintain the state where the connection opening end portions are fitted to the associated pipe end openings, respectively.

A hose adapter may include an outer tube, an inner tube, a hose connector, and a hose. An inner peripheral ring protrudes from the inner periphery of the outer tube while an expanding ring portion protrudes from the outer periphery of an end of the inner tube. The outer periphery of the inner tube further has a first peripheral recess, a second peripheral recess, and a first outer thread, and a first O-ring and a second O-ring are respectively disposed on the first peripheral recess and the second peripheral recess. The inner tube is inserted into the outer tube, and the expanding ring portion is abutted against the inner peripheral ring, and the first O-ring is coupled between the outer tube and the inner tube while the second O-ring and the first outer thread are adapted to pass through and be exposed out of the outer tube.

An externally driven conveyor pulley with an integrated thermal control system by which the temperature of the pulley may be controlled whether the pulley is rotating or stationary. The present invention includes a rotary connection device (or plurality of such devices) designed to transfer fluid (liquid or gaseous) or electrical current into/out of a rotating object. The rotary connection device may be a slip-ring for electrical power transfer or a rotary union for liquid transfer, but any device designed to transmit fluid or electricity into a rotating object could be utilized. In one embodiment, temperature control is achieved by transmitting temperature controlled fluids through the pulley via at least one rotary connection device. In an alternative embodiment, temperature control is achieved by transmitting electricity via the rotary connection device to a temperature regulating device in the rotating object. The temperature regulating device could be any electrical heating or cooling unit.

A watering nozzle including a handle configured to be grasped by a user, an inlet connector including a flange rigidly coupled to the handle, and an inlet engagement feature, a swivel coupling including a garden hose thread and a swivel shoulder adjacent a swivel opening arranged concentrically about a central axis, the swivel coupling rotatable relative to the handle about the central axis, and an insert shank including a swivel seal in sealed contact with the swivel coupling, a first shank shoulder in contact with the swivel shoulder, and a shank engagement feature in rigid engagement with the inlet engagement feature.

An embodiment of this invention provides a swivel joint for a working machine that makes it easy to install a device for detecting rotation angle and is able to suppress the increase of the size due to the installation of the device. An embodiment of the present invention includes the swivel joint that includes an outer body being secured on one of the lower traveling body and the upper swiveling body and having a blocking surface on one end; an inner body being secured on another of the lower traveling body and the upper swiveling body and being relatively and rotatably fitted in the outer body while opposing to the blocking surface at one end n in the manner of making a space; a pilot oil passage being formed on rotational center line CL of the inner body for distributing pilot oil; a rod being inserted into the pilot oil passage and being secured on one of the outer body and the inner body; and a rotation angle sensor being secured on the other end of the outer body and the inner body for detecting a rotation angle of the rod.

A plug and pump system for routing pressurized fluid from a fluid source is disclosed. The system includes a platform and a docking station interface mounted on the platform and including multiple points of articulation. A wellhead interface is mounted on the platform and includes multiple points of articulation. The docking station interface and the wellhead interface are configured to route pressurized fluid from a fluid source.

A technique facilitates enhanced sealing capability in a space saving format when utilizing a plurality of uniquely constructed seals. As a result, the seals are useful in swivels and other types of structures to provide secure sealing between seal surfaces while reducing the overall seal area. Each seal comprises a body having a seal base combined with lips which may be activated when the activation fluid is supplied under pressure. In swivel applications, the seals may be constructed in a vertical orientation as axial face seals. The vertical orientation of the seals enables construction of the swivel with a reduced cross-section and thus a reduced hydraulic loading.
