Abstract: A quick connector with a one-way flow valve includes a bearing cage mounted in a bore of a female component housing and supporting a tip end of a conduit lockingly held in the housing by a retainer. A projection extends from one end of the bearing cage and spaces a flow ball movably mounted in the housing bore at a first, flow permitting open position wherein flow paths between the male and female components are established around the exterior of the flow ball and between circumferentially spaced ribs formed in the housing and supporting the flow ball. The flow ball is automatically movable in response to a reverse direction acting fluid pressure differential to a second, flow-blocking position in sealing engagement with a valve seat formed in the housing bore to prevent reverse fluid flow through the connector.

Abstract: A quick connector for connecting fluid lines includes a first connector having a housing for receiving a tube carrying spool. The spool sealingly engages an endform on the tube to form a metal-to-metal seal. A retainer in the form of ring having a plurality of angularly and radially extending, resilient legs extending therefrom and terminating in end pads is mountable in the housing in engagement with the spool with the end pads disposed in an annular, inward facing channel in the housing. A pop top is slidable along the tube to bias the retainer legs radially inward to allow insertion of the retainer into the bore in the housing and then is removed to allow the legs to snap radially outward bringing the end pads into engagement with housing channel. An assurance clip is mountable interiorly between the legs of the retainer and the spool to maintain the retainer legs in a radially outward position in engagement with the channel in the housing.

Abstract: A release tool for a quick connector with a radially displaceable retainer has a pair of arms extending from a collar which are normally disposed on axially extending surfaces of the housing of the female component of the quick connector when the release tool is mounted on the housing. A retainer engaging surface on each of the arms is movably engageable with projections on side legs of the retainer to urge the projections and the end portions of the side legs of the retainer radially inward to a position where the projections are disengaged from lock edges on the axially extending surfaces of the housing to allow disengagement of the retainer element from the male component of the quick connector.

Abstract: A Hybrid Quick Connector for releasably interconnecting fluid carrying tubular members has a housing with first and second portions which are joined together to establish a through passage for fluid communication of the tubular members. One housing portion defines a first bearing surface and a retainer for releasably engaging an end form of one of the members. The other housing portion is permanently affixed to the end form of the other member and defines a second bearing surface which is axially spaced from the first bearing surface to straddle a resilient seal. Upon insertion of the first tubing end form, a retainer locks it in assembly with the quick connector and the seal acts to block the only potential leak path.

Abstract: A process of preparing a ferrierite-type zeolite, with high crystallinity rate and having a anhydrous stage composition expressed by the formula M.sub.x (AlO.sub.2).sub.x (SiO.sub.2).sub.y, M being a cation of an alkaline metal such as Na or K, or a mix of both. The process contains a gel-producing step, by addition of boric acid to an aqueous aluminum-sulfate solution mixed with a aqueous solution containing oxides of Na and/or K and of Si, without the use of a structural agent. The invention also pertains to any zeolite obtained by this process, and its uses.

Abstract: A retainer for releasably locking together the male and female component of a quick connector. The retainer is releasably insertible into a transverse bore in the female component and includes a surface slidable over a radial flange on the male component only when the male component is fully seated in an axial bore in the female component. The engagement of the surface and the radial flange on the male component permits full insertion of the retainer into the transverse bore in the female component and around the male component to lock the male and female components together. Lock projections on the retainer engage grooves in the housing to releasably lock the retainer in a partially inserted, shipping position in the transverse bore and engage exterior lock surfaces on the housing on full insertion of the retainer to prevent separation of the retainer from the female component.

Abstract: A quick connect coupling including a female connector member adapted for quick connect engagement with a male connector member. The male connector member has an annular bead defined by leading and trailing annular edges. The female connector member defines an axial bore sized to slidably receive a leading end of the male member defined forwardly of the leading annular edge of the bead and a plurality of circumferentially spaced resilient fingers adapted to snap into position behind the bead and into engagement with the trailing annular edge of the bead as the leading end of the male member moves into the bore and the leading annular edge of the bead moves into engagement with a radial seating surface defined around the entrance to the bore.

Abstract: A retainer for releasably locking the male and female components of a quick connector. The retainer is releasably insertible into a transverse bore in the female component and is blocked from full insertion by a projection. An extension projects from the retainer and has an aperture sized to receive the tip end of the male component, but not a radial flange on the male component when the retainer is partially inserted into the female component. Forced insertion of the male component breaks off a ring portion of the extension thereby enabling the radial flange on the male component to fully move into the female component. The retainer can then be urged into the fully latched position locking the male and female components.

Abstract: An insertion indicator for a metal quick connector assembly includes an annular base adapted to be releasably received within the mouth of a female connector component's axial bore, such that the male end form of the connector assembly's male component, including an external flange thereon, is insertable through the indicator's base into the axial bore. The indicator further includes two legs projecting both axially and radially-inwardly from its base so as to extend deeper within the female component's axial bore than the "locking" abutment surfaces of a retainer, also disposed within the bore, when the indicator is releasably received therein.

Abstract: A retainer for releasably locking the male and female component of a quick connector together. The retainer is releasably insertable into a transverse bore formed in the female component and includes an edge slidable over a radial flange on the male component only when the male component is fully coupled in an axial bore in the female component. The engagement of the edges and the radial flange on the male component permits full insertion of the retainer into the transverse bore in the female component around the male component to lock the male component and female component together. Lock projections on the retainer engage grooves in the housing to releasably lock the retainer in a partially inserted, shipping position in the transverse bore in the female component and engage exterior lock surfaces on the housing on full insertion of the retainer to lock the retainer and the fully inserted male component to the female component.

Abstract: The present invention is a high pressure quick connector especially for use in connecting brake lines of a vehicle. The connector includes a housing which selectively receives a tube retainer cap. Retaining means such as a garter spring or snap ring allow for a low force insertion of the cap into the housing with an very high pull-off force. The cap is used to trap a tube with a bead upset, and the tube may be removed after the cap is unlocked. A second way of releasing the tube includes the use of a tube retainer plug selectively received in the cap, the upset trapped between the plug and cap. The plug can be removed while the cap is still locked in the housing, releasing the tube. A release tool may be used to unlock the cap from the housing. An insertion indicator ring is used to establish the locking of the cap within the housing. A dust boot prevents contaminants from interfering with the operation of the connector.
