  • Patent number: 8746748
    Abstract: A coupling system includes two base bodies, each having an aperture for a fluid, an interior predefined circumferential depression and a locking surface. An adapter piece including an aperture for the fluid has two ends and at least two predefined circumferential depressions, which run at least partially along a circumference of the respective ends, wherein the first base body is associated with the first end of the adapter piece and the second base body is associated with the second end of the adapter piece, wherein in a state in which they are pushed inside each other the circumferential depression associated with the respective end of the adapter piece and the interior circumferential depression of the respective base body are located opposite of each other and form a receiving space. In addition, latching elements are provided to prevent the respective latching element from accidentally sliding out of the associated receiving space.

  • Patent number: 8746751
    Abstract: A threaded adapter is part of a quick-to-connect and quick-to-disconnect flexible hose coupling system. The adapter may provide a low-profile securement and seal between the port and the stem portion of the quick connect coupling. The adapter in combination with the fluid valve block orifice provides a seal that is further down in the valve block than the location of seals provided by other fluid couplings. Without relying on wrenching flats, the adapter also provides effective access to the hoses for repair and therefore is a cost saving device. The adapter may be a safe, reliable, easy to connect and disconnect component in a hydraulic system and is adaptable to accommodate any coupling including those in high and low pressure fluid and other systems.

  • Patent number: 8746750
    Abstract: A clip for a quick connect hose coupling that possesses an improved combination of characteristics leading to a quick connect coupling that can be connected reliably, consistently, and with reduced damage to the coupling and low insertion force. The clip provides reduced friction against the fitting and reduces insertion force and damage. The clip has two end portions that are designed to be deflected relative to each other when the stem is inserted into the port. The clip further has a periphery with two end portions, each curved at or beyond the radius of maximum installation deflection such that they will not scrape the installation ramp.

  • Publication number: 20140145431
    Abstract: A mechanical coupling between a straight pipe end and a socket fitting comprises a seal ring and a locking ring disposed within the interior of the socket. The locking ring has a generally frusto-conical shape with a plurality of corrugations extending circumferentially thereabout, the corrugations presenting inner edge portions engaging the outer annular surface of the pipe end and outer edge portions engaging the interior annular surface of the socket for opposing withdrawal of the pipe end axially outwardly from the socket. In an advantageous embodiment, the locking ring is assembled with a support disk to optimally orient the locking ring with respect to the fitting and the pipe end.

  • Patent number: 8720574
    Abstract: A subsea connector that includes a connector capable of selectively connecting to a spool body to form a connector assembly. The subsea connector may include an adapter ring that is capable of connecting the spool body to the connector. The connector assembly may be lowered onto a wellhead member and locked into place by a movable piston and split lock ring. While the connector assembly is in the unlocked state, the adapter ring may be rotated moving the connector up or down with respect to the spool body, which lands on the wellhead member. The movement of the connector may be used to vary the alignment of the connector locking means with respect to the locking profile of the wellhead member. This change in position may be used to modify the preload force applied to the connector when locked onto the wellhead member.

  • Patent number: 8696039
    Abstract: Various novel connectors are provided. In one embodiment, the connector includes a collar configured to receive first and second components. In this embodiment, the connector may also include a load ring configured to be received in a groove of the second component and to move into and out of engagement with the collar when the second component is received by the collar. The connector of this illustrative embodiment may also include a cotter configured for installation to the second component and to inhibit disengagement of the load ring from the collar. In some embodiments, engagement of the load ring and the collar effects securing of the first and second components to one another. Other devices, systems, and methods related to connectors are also disclosed.

  • Patent number: 8657343
    Abstract: A connector assembly including a connector body having a coupling end and sealing means. A collet couples to the connector body and has resilient fingers. An adjustment ring has a stop and defines guide tracks. A collar has protrusions coupled in the guide tracks. A ferrule is slidingly housed within the collar and adjustment ring. A locking split ring clips onto the adjustment ring to limit travel of the collar. In a locked position, the locking split ring is installed and a pipe, inserted into the connector body is retained in place by the resilient radially inward fingers of the collet and sealed by the sealing means. In the released position, the collar has been moved to force the ferrule into the collet to splay the resilient fingers such that the pipe is freely insertable and removeable from the connector assembly.

  • Publication number: 20140021717
    Abstract: A connector assembly for establishing fluid communication between a copper pipe and a cross-linked polyethylene (PEX) tube is provided. The connector assembly additionally includes a retainer including a plurality of teeth. In operation, the copper tube is inserted into a female receiving portion of the housing and a fluid-tight seal is established therebetween. Then, a PEX expansion ring is expanded radially outwardly and inserted over the retainer and contracted to urge the teeth against the copper pipe, thereby retaining the copper pipe inside of the housing. Next, an end of the PEX tube and another expansion ring are expanded radially outwardly and inserted over the male end form of the housing. This PEX expansion ring then contracts to establish a fluid-tight seal between the PEX tube and the male end form of the housing.

  • Patent number: 8613473
    Abstract: A plug-in connection for hydraulic lines and machines, in particular for use on motor vehicles, has a receiving part and a complementary associated plug-in part which is sealed off from the receiving part in the final assembled position. When the plug-in part is inserted into the receiving part, a spring-elastic securing element, which is fitted captively and in a prestressed manner as a spring force storage device on the receiving part in a pre-assembly position, is displaced by the plug-in part relative to the receiving part in such a way that, when the final assembled position is reached, its stored spring force is released by the joining movement itself and the securing element latches in a force-fitting manner between bearing surfaces of the receiving part and of the plug-in part.

  • Patent number: 8561274
    Abstract: A connector includes a housing having a bore with a housing groove disposed on an inside surface of the bore with a groove establishing a release angle between a housing groove bottom and a bore inside surface. A retainer defines a spring cavity between a retainer and the release angle and a circular radial canted coil spring is disposed in the spring cavity. A pin having a tapered end and a body diameter sized for sliding engagement with the bore is provided which includes a circumferential groove in the pin body for receiving the coil spring upon insertion of the pin into the bore. A circumferential groove includes a load angle for rotating the coil spring in an orientation in which the major spring axis is parallel to the release angle upon initial withdrawal of the pin from the bore. The coil is further compressed along the spring minor axis and expands radially upon continued withdrawal of the pin from the bore.
