摘要： A trailer hitch assembly includes a receiver portion including a cylindrically-shaped cavity, a bushing member received within the cavity of the receiver portion, and a hitch member that includes a shaft pivotally received within the bushing member. At least a selected one of the bushing member and the shaft is constructed of a material that substantially eliminates the need for using a separately applied lubricant during use of the trailer hitch assembly. The hitch member also includes a first jaw member, a second jaw member coupled to the first jaw member and operable between open and closed positions, a primary latch coupled with the second jaw member and operable between a locked position preventing opening of the second jaw member, and an unlocked position allowing opening of the second jaw member, and a secondary latch coupled with the primary latch and operable between a locked position preventing unlocking of the primary latch, and an unlocked position, wherein the primary latch may be moved to the unlocked position thereof.

摘要： A pipe coupling (10) for joining together the ends of two adjacent pipes includes a housing (12) which defines a generally central bore (13) along a central axis of the housing for receiving the ends of the two adjacent pipes, and a locking arrangement (14) at each end of the housing (12) for locking the pipes to the coupling. Each locking arrangement (14) includes an annular chamber (23) within the housing, an inlet for allowing fluid into the chamber, an outlet for allowing fluid out of the chamber, and an annular seal (24) which is arranged to move within the annular chamber axially of the housing. A locking ring (26) is provided between the annular seal (24) and a plurality of radially movable grippers (30) for locking the grippers to a pipe end within the housing. Th locking ring (26) includes a sloping inner surface (28) which is engageable with a corresponding sloping outer surface (32) on each of the grippers (30) to that axial displacement of the locking ring under fluid pressure within the annular chamber (23) causes radial displacement of the grippers (30) towards the central axis of the housing (12) for clamping the pipe end within the housing.

摘要： A ramp-lock quick-connect fitting is adapted to be placed between conventional type fittings on pipes and tubes, such as quartz pipes and synthetic resin tubes used in chemical processing systems for semiconductor device fabrication. The quick-connect fitting includes a first coupling member having a pipe receiving section adapted to receive a conventional fitting on a pipe, and a ramp support section with a pair of spiral ramps formed therearound. The quick-connect fitting also includes a second coupling member that sealingly engages the first coupling member. An extension portion of the second coupling member is adapted to receive a conventional fitting on a tube. A locking collar is movably engaged with the second coupling member and has a pair of lock members disposed on an interior surface of the collar that slidably engage with the spiral ramps when the collar is rotated around the ramp support section of the first coupling member.

摘要： Bolt bores in lower members each comprise a large-diameter portion larger than the head of a bolt in diameter, and a small diameter portion extending downward from the large-diameter portion with a stepped portion formed therebetween and having a diameter intermediate between the diameter of the bolt head and the diameter of the shank of the bolt. A heat insulator has a spacer inserting hole. A hollow cylindrical spacer having an inside diameter larger than the diameter of the bolt shank is inserted through the small-diameter portion of the bolt bore and the spacer inserting hole so that the upper end of the spacer is positioned in the large-diameter portion. The spacer has a lower end bearing on a support member. A hollow cylindrical elastic member is interposed between the bolt head and the stepped portion for biasing the lower member toward the support member.

摘要： A plug-in coupling for pressurized systems having two coupling components (2, 4), namely a receiving component (2) and a connector component (4). The connecter component (4) includes a connecting shaft (6) which is inserted into a locator opening (8) of the receiving component (2) and is sealed around the perimeter and arrested against loosening by a holding element (20) situated in a recess (22) of the receiving component (2), first in a partially inserted, incompletely sealed, pre-locked position and secondly in a fully inserted, perfectly pressure sealed full lock-in position. The holding element (20) has arresting elements (28, 30) each of which engage behind a locking edge (24) of the connector component (4) when a lock-in connection (28, 24; 30, 24) is formed. The holding element (20) is relatively movable axially in the recess (22) of the receiving component (2) in such a way that at least in a full lock-in position, at least one arresting element (30) can be transferred, by shifting of the holding element (20) against the direction of insertion, from an unlocked position in which the respective lock-in connection (28, 24; 30, 24) can be released, to a locked position in which release of the lock-in connection (28, 24; 30, 24) is prohibited.

摘要： A plug-in coupling for pressure application systems, including two coupling components such as a housing component and a connector component. The connector component is sealed insertable into a locating opening of the housing component, and is arrestable against loosening by a locking device. The locking device has an elastically deformable holding element, which is located on the side of one coupling component in such a way that, in the inserted state, it engages behind an arresting step of the other coupling component, locking with positive fit, for arresting said connector component. The holding element is designed ring-shaped and comprises several individual annular segments and one concentric spring lock washer component which presses the annular segments with radially operating spring resistance that each annular segment can move radially against or through the spring resistance of said spring lock washer component during the plugging-in.

摘要： The present invention relates to a branch pipe connection including a locking ring and a sleeve that are arranged against one another and can be tightened in their axial direction. The connection further includes a support flange. The locking ring is of such a flexible material that the locking ring can be placed inside a pipe or the like through a hole made for the branch pipe from outside the pipe or the like, although the smallest outer diameter of the flange of the locking ring is larger than the largest diameter of the hole.

摘要： A preassembled fitting including a body, a nut and a collet positioned within the nut. The nut is threaded on the body a predetermined distanced to allow the installer to snap the corrugated tubing into the nut and engage the collet. The nut is then further tightened to seal the body to the corrugated tubing. A tapered surface on the body engages the cut end of the corrugated tubing and flares the cut end of the corrugated tubing. The fitting will make a metal to metal seal by folding the convolutions of the tubing back against itself creating a double flare.

摘要： The invention relates to a hose coupling device, which comprises a male part connectable to a female part. The female part consists of a sleeve, which is provided with a number of resilient tongues extending in equally spaced relationship along the inner wall of the sleeve and protruding inwards form the inner wall and directed away from the mouth of the sleeve. The male part consists of a tube portion with transverse edges in its outer wall. At the insertion of the male part into the female part the resilient tongues are arranged to resiliently snap into place behind the transverse edges of the male part and hence connect the female part to the male part. The parts can be separated by turning them relative to one another to a position where the resilient tongues assume a position laterally of the transverse edges.
