Disclosed is a swivel including inner and outer mutually rotatable swivel members having respective inner fluid paths communicating with each other through an annular space at an interface between the swivel members and being provided with a sealing arrangement on a side of the annular space at the interface including a peripheral groove provided in the inner and/or outer swivel member, and a sealing element received therein and arranged for static sealing against a first one of the swivel members, inside the groove and for dynamic sealing against a second one of the swivel members, a surface inside the groove in the first one of the swivel members abutting the sealing element being a textured surface extending along at least a part of one or more inner surfaces of the groove and having three-dimensional textural elements for making frictional contact with the sealing element.

A universal tube adaptor for a shock absorber includes a connector body, and first and second connectors. The connector body has intersecting first and second connecting holes respectively and rotatably receiving the first and second connectors rotatably therein. The first connector has a first guiding hole and an overflow hole perpendicular to, in fluid communication with, and cooperating with the first guiding hole to define an oil-filled space in fluid communication with the second connecting hole. The second connector has a second guiding hole in fluid communication with the second connecting hole and the overflow hole, so that the second guiding hole, the oil-filled space and the first guiding hole cooperate with one another to define an oil passage permitting damping oil to flow therein.

A device is disclosed for coupling a coolant supply and/or coolant drainage to a roll, especially in a continuous casting installation, wherein the roll includes a journal, which is mounted rotatably in a bearing block, and a lateral recess, extending in the axial direction, and at least one roll cooling channel, through which a coolant can pass. The device includes at least one coolant channel, which can be brought into fluidic connection with the roll cooling channel on the journal side; and a sealing unit for sealing the fluidic connection between the coolant channel and the roll cooling channel, including an inner module and an outer module. The inner module includes a hollow cylindrical element, which can be inserted into the lateral recess of the journal, and which, when viewed in the axial direction, has no flange on the outer side of the journal.

A boom turret for a debris body. The boom turret includes an inlet defining an inlet axis and configured to couple to a hose. An outlet defining an outlet axis and configured to rotatably couple to the debris body. The inlet axis is substantially orthogonal to the outlet axis and a debris flow path is defined within the boom turret between the inlet and the outlet. A plate is disposed between the inlet and the outlet and has a surface at least partially defining the debris flow path through the boom turret. A nozzle is coupled to the plate and extends into the debris flow path. A pressure vessel is configured to hold a charge of pressurized fluid, and the pressure vessel is coupled in flow communication with the nozzle and selectively releases the charge of pressurized fluid through the nozzle to dislodge accumulated debris within the debris flow path.

Provided is a connection mechanism for connecting a tube through a joint to a housing of a valve. At least one of the housing of the valve and the joint is made of a resin. The housing of the valve includes a connection hole for inserting and connecting the joint, and pin insertion holes which is drilled from an external surface of the housing in a direction orthogonal to an axial direction of the connection hole, and penetrates through the connection hole. An annular groove is formed along a circumferential direction of an outer peripheral surface of the joint. In an insertion state of the joint into the housing, the pin is inserted from the pin insertion holes on the external surface of the housing. The pin passes through the annular groove disposed on the joint and comes into engagement with the joint.

An articulated conduit device may include at least two arms pivotally connected at proximal ends of the arms by a joint, a tiltable adapter at a distal end of each of the arms, capable of tilting up to a predetermined angle, and a locking mechanism operable by a single action to concurrently lock or unlock the arms and adapters in a user-defined orientation and direction. A continuous cavity is defined within the device between external openings in the adapters and through the arms and joint so as to allow fluid to flow between the external openings of the adapters.
