A fitting assembly includes a fitting and a tube. The fitting has a fitting body having a straight through hole and an attachment or base port, connected to the through hole by a first passageway generally perpendicular to the through hole. The tube has an outer diameter smaller than the through hole allowing a first end of the tube to pass through the through hole. A seal is positioned in one of a circumferential slot in the tube and a circumferential slot in the through hole of the fitting body, the seal sealing a second end of the tube to the fitting body. A cover is sealingly attached to the first end of the through hole. One of the cover and the tube has a portion that extends into an intersection of the through hole and the first passageway, the portion having an aperture that prevents blockage between the attachment or base port and the second end of the through hole.

Provided is a linear movable rotary union including a driving shaft comprising a plurality of fluid supply paths; a hollow middle housing surrounding an outside of the driving shaft and comprising a plurality of first through holes in a sidewall; a plurality of first sealing members provided between the middle housing and the driving shaft to prevent leakage of a fluid; a hollow outer housing surrounding an outside of the middle housing and comprising a plurality of second through holes in a sidewall; and a plurality of second sealing members provided between the middle housing and the outer housing to prevent leakage of the fluid, and wherein the driving shaft is installed to be capable of rotational motion in the middle housing, and the middle housing is installed to be capable of reciprocating motion in an axial direction in the outer housing.

A quick connect fluid connector is directly connected to a fluid port of a fluid manifold using a quick connect fluid connector swivel that is configured to permit rotational and/or longitudinal movement of the quick connect fluid connector relative to the fluid port. The relative axial and/or rotational movements provided by the swivel eliminates the need for a fluid hose to be used in the fluid path between the quick connect fluid connector and the fluid port.

A mixer valve (1) having a body (2) and adapted to be connected to two fluid supplies. The mixer valve (1) has at least one connector (6) comprising a housing (8); a fluid delivery tube (10) within the housing, the fluid delivery tube (10) having at least one aperture (22); a slider (16) arranged around and slideable over the delivery tube (10) and having an interior chamber (18) in fluid communication with an interior (20) of the delivery tube by means of the at least one aperture (22); and a fluid inlet (14) connected to the slider (16) at an angle thereto, the fluid inlet (14) being connectable to a fluid supply pipe. The fluid inlet (14) is in fluid communication with the chamber (18), and the housing (8) has an external opening (12) within which the fluid inlet (14) is located and movable.

The disclosure describes a rotary union that includes rotating and non-rotating machine components, each having a sealing ring, which can together form a mechanical face seal. A rotor disposed on the rotating machine component includes one or more magnets. A sensor array disposed in the housing includes a plurality of sensing elements that are integrated with a control device, a communication device, and a power storage device. The sensor array further includes a magnetic pickup coil disposed to closely overlap the outer periphery of the rotor. When the rotating machine component rotates, the magnet creates a rotating magnetic field that cooperates with the magnetic pickup coil to produce electrical power to operate the sensor array.

A rotor including an internal fluid opening extending in a radial direction through the rotor and two ring seals disposed in opposed orientation on the rotor. Each of the two ring seals sealably and slidably engages the rotor. A stator is disposed around the rotor and the two ring seals and forms an external fluid opening extending in the radial direction through the stator. The stator includes two ring flanges disposed at axially distal ends thereof. Each of the two ring seals slidably contacts a respective one of the two ring flanges to form a mechanical sliding face seal.

A connection ring is provided for removable attachment of a fuel supply unit on a fuel tank. The connection ring has a ring upper side, at least one attachment elevation which protrudes from the ring upper side, and at least one tool engagement region. The tool engagement region is constructed such that a torque from a tool can be transmitted onto the connection ring. At least one portion of the tool engagement region and one portion of the attachment elevation are at an equal distance from the center of the connection ring in the radial direction from the center.
